First things first: Gather your cleaning gear! You’ll need:

3 Easy Steps – How to Clean the Exterior of Your Weber Grill

Your Weber’s shiny exterior deserves some TLC – and keeping the outside of your Weber grill in top shape helps protect it.

Before you get started, make sure your grill is cool to the touch! We don’t want you burning yourself.

1. Wipe it Down

Start by washing the grill’s exterior with warm, soapy water and get scrubbing. Water and soap is gentle enough for all surfaces – whether it’s stainless steel, painted, or porcelain-enamel coated. 

Make sure to give the grill a good rinse and dry it thoroughly with a soft cloth.

2. Polish Stainless Steel Parts

Use a non-toxic stainless steel cleaner and a microfiber cloth to buff the grill, always moving in the direction of the grain. This is to make sure you don’t scratch the surface.

Skip the paper towels for this one – they can leave scratches on your stainless steel grill!

3. Special Care in Tough Environments

Do you often take your BBQ with you to the beach? Sounds fun! But if your grill is near the ocean (and salt water), you should clean the exterior more often. You may want to use a stainless steel cleaner weekly to prevent surface rust.

Bonus Tip: Take Inventory While You Clean

Grill parts wear down over time. So while you’re sprucing up your grill, we recommend you take a mental note of any parts that might need replacing

Need new cooking grates, flavorizer bars, or even a burner tube? No problem! Replacing them is easy, and it’s a sure way to keep your grill working like new for years to come.

Head over to our grill parts selection and find replacement parts for your Weber grill. We have parts for over 2037 models!

How to Clean the Interior of Your Weber Grill

The inside of your grill needs a little tender care, too. A clean interior not only helps your food cook evenly but also prevents pesky flare-ups caused by grease build-up.

1. Clean the Lid

Ever noticed flakes on in the inside of your grill’s lid? Don’t worry, that’s not paint! It’s carbon buildup from grease and smoke, which eventually peel and look similar to paint. 

Though it’s not toxic, it’s good to clean it on a regular basis. It helps keep your grill performing at its best and keeps those flakes from landing on your food.

  • Use your grill brush to scrub away the carbonized grease from the lid.
  • Wash it down with warm soapy water and a sponge to leave it fresh and ready for your next cookout.

Notice any discoloration? Use the soapy water and a sponge with a non-lint cloth to remove any of that excess residue.

Pro tip: Clean the inside of the lid with a paper towel after grilling each time (when it’s warm, not hot).

2. Scrub Those Grates

Time to focus on the business end – the grates! It’s best to clean them after each use.

Here’s how to do it:

  • Start by preheating your grill on high for about 15 minutes with the lid closed. This helps burn off any food remnants.
  • Use your grill brush – wait until the grill has cooled – then use a greate cleaner and a scouring pad to get those grates sparkling.

3. Show Some Love to the Flavorizer Bars

Your flavorizer bars catch all those tasty drippings, but they need a little cleaning every now and then. 

  • After grilling, let your grill cool completely, then scrape the bars with a plastic scraper to remove any stuck-on food.
  • Use a stainless steel grill brush for any stubborn spots then wipe clean with a rag and warm water.
  • Does your grill have heat deflectors? Then follow the same instructions as with a flavorizer bar.

Don’t forget to check for cracks or holes. If your flavorizer bars are looking worse for wear, it might be time to replace them! 

4. Clean the Burner Tubes

For excellent grill performance, your burner tubes need some attention, too! They’re essential for safe and even cooking, so don’t skip this step!

Cleaning them regularly keeps your grill firing on all cylinders.

  • Remove the cooking grates and flavorizer bars to get to the burner tubes. You’re going to have to clean each tube individually.
  • Clean the burner ports by brushing up and down (never side to side!) with your grill brush to avoid pushing debris into the ports – otherwise, you might cause gas flow issues.
  • If your Weber grill has control knobs on the front (like the Genesis models), brush left to the right. For models with knobs located on the right side (like the Spirit or an older Genesis model) brush up and down.

5. Deep Clean: The Cookbox and Grease Management

Weber grills have a nifty grease management system that helps prevent flare-ups by catching grease in a drip pan. But you still have to keep it clean!

  • Scrape the cookbox: Use a plastic scraper, a putty knife, or a straight-edged object to scrape any grease or food buildup from the siders and bottom of the cookbox. Let the debris fall into the opening leading to the grease tray.
  • Clean the grease tray and drip pan: Slide out the tray and scrape off any grease. Clean it with soapy water and a scoring pad. Don’t forget to replace the disposable aluminum drip pan regularly to prevent grease fires!

Pro tip: Never line the bottom tray with foil – this can restrict airflow and affect performance! 

And There You Have It!

That’s all we’ve got for now! With a bit of elbow grease, your Weber grill will be looking shiny and new – and ready for your next BBQ! 

Remember: regular cleaning means fewer repairs and a longer grill life.

With these simple steps, your grill will not only last longer but also cook like a dream, keeping those burgers and steaks tasting as good as ever.

Now go fire it up – and happy grilling!

Love your flat-top grill or griddle, but not as much the cleanup? We hear you! Whether you’re flipping burgers, grilling steaks, or anything in between, these grills can get messy fast. 

But don’t worry – cleaning doesn’t have to be a pain.

In this guide, we’ll show you how to clean a flat top grill – whether it’s a Blackstone or another brand.

From everyday cleanups to tackling rust, this guide will show you how to clean a griddle grill quickly and easily, so you’re always ready to cook!

How Often Should You Clean Your Flat-Top or Griddle Grill?

The golden rule? Clean your flat-top grill after every use

The more often you clean it, the less work it’ll be later. If you stay on top of things, deep cleaning will only be necessary now and then. It means less time scrubbing and more time cooking!

Is nothing working? Then it might be time for some new grill parts. Check out our range of replacement grill parts to keep your flat-top in shape!

Why Cleaning Matters: Great Taste Starts with a Clean Surface

A clean grill isn’t just for looks – it’s for flavor!. Cooking on a dirty surface is no fun, and it can mess with the flavor of your food.

So, let’s walk you through how to clean your griddle after cooking – and maybe give it a little TLC along the way! 

Step-by-Step: How to Clean Your Flat-Top Grill After Cooking

Cleaning your grill after each use is a must. Leftover food bits can stick, attract bugs, or even mess with the taste of your next meal. 

Here’s your step-by-step guide to keep things simple:

1. Heat It Up

Crank up the heat and let your grill get nice and hot. This loosens up leftover food and grease, making it easier to scrape off

Plus, there’s something satisfying about seeing all that gunk disappear!

2. Scrape it Clean

With a handy grill scraper (your new best friend), scrape off any food bits or grease. This keeps that smooth cooking surface ready for your next masterpiece

Don’t forget to wear your heat-resistant gloves for this step! 

3. Add Water

Grab some warm water and slowly pour it onto the surface. The steam helps release any stubborn food, making it even easier to clean. Go over the surface with your scraper one more time for good measure.

4. Cool and Oil

Let the grill cool down a bit, then spread a light layer of cooking oil across the surface. This keeps everything non-stick and prevents rust! You can easily use a paper towel to spread the layer around

… just don’t add too much oil, or your next cooking will be affected! A few tablespoons is fine. 

How to Clean a Flat-Top Grill with Rust – Easy Fix! 

Uh-oh, rust got you down? It happens to the best of us. If you’ve let your grill sit for a while or live in a humid area, rust can sneak up on you. Not to worry – we’ll show you the steps to getting it back to its shiny self! 

Here’s how to clean a flat-top grill that has rust:

1. Scrub the Rust

Grab some steel wool or a grill brush and give those rusty spots a good scrub. It may take a little elbow grease, but you’ll get there – just be careful not to scratch the surface too deeply.

2. Vinegar to the Rescue 

Mix equal parts vinegar and water, pour it on the rusty areas, and let it sit for a few minutes. Scrub again with a grill brick or scraper and watch the rust disappear.

3. Rinse and Dry

Once the rust is gone, wipe down the grill with a clean rag and make sure it’s completely dry to avoid any future rust.

4. Re-Season the Surfaces

After tackling the rust, add a fresh layer of oil – not only to protect your grill but also to get it ready for your next cookout!

How to Clean a Blackstone Grill – An Outdoor Favorite

If you’re the proud owner of a Blackstone grill, you know it’s great for outdoor cooking! But like any grill, keeping it clean is key to making sure your food tastes amazing every time.

Luckily, it’s just like cleaning any flat-top grill! 

Heat it, scrape it, add water, and scrape again. And don’t forget to season with the thin layer of oil! Your Blackstone will love you for it – and so will your taste buds! 

If cleaning isn’t doing the trick, and your Blackstone grill is still not cooking like it used to, it might be time for some new parts! Check out our selection of Blackstone grill parts and get your trusty grill back in shape! 

Deep Cleaning: When Regular Cleaning Isn’t Enough

If your grill has been sitting for a while or you’ve had some heavy-duty cookouts, you might need to go for a deep clean. 

Here’s how to bring your flat-top grill back to life:

1. Scrub with a Grill Stone

Gently scrub the surface with a grill stone and a bit of oil. This will tackle any stubborn buildup. Just don’t go too hard – you want to avoid scratching the surface.

2. Repeat as Needed

If there’s still gunk, go through the cleaning steps again until it’s spotless. A little patience now saves a lot of hassle later! Also try using steel wool or even sandpaper.

3. Apply a Final Coat of Oil

We cannot emphasize this tip enough: once your grill is clean, add a final layer of oil to protect it. Don’t overdo it – a thin coat is enough to protect it for the next use. 

4 Pro Tips to Keep Your Grill in Great Shape

  1. Store your grill scraper and cleaning tools nearby for quick access after every cook.
  1. Clean while the grill is still warm – it’s way easier to remove food bits when they’re fresh!
  1. Always finish with a layer of oil to prevent rust and keep your grill smooth.
  1. If you see rust, tackle it right away to prevent it from spreading.

We’ve all been there: you’re ready to grill, and then, oh – your grill grates look like they’ve seen better days. 

Whether it’s last week’s burger remnants or caked-on grease from your last big BBQ party, it’s time to give those grates some love, don’t you think? 

But hey – don’t worry. 

We’ve got all the tips and tricks you need to keep your grill grates ready for the next grilled meal!

Why Cleaning Grill Grates Matters

Cleaning grill grates may not seem like a big deal. But trust us, it impacts more than just appearance

Leftover residue can affect the taste of your food and even cause flare-ups. Plus, regular cleaning helps prevent rust, keeping your grates functional longer.

So, whether you’re looking to clean grill grates after a big barbeque or get ready for the next cookout, this is the guide for you! 

PS. if you’re rocking a Traeger grill or a Weber grill, we’ve got dedicated guides for how to clean a Traeger grill and how to clean a Weber grill!)

5 Pro Tips for Cleaning Grill Grates Effectively

Before we dive into the materials, here are some golden nuggets of wisdom to make the process smoother, quicker, and a lot less difficult for you:

  1. Preheat the grill first: This tip is pure magic. When the grill is hot, food and gunk come off much easier. Give it a good 10-15 minutes on high, and then scrape off the debris with a grill brush or scraper.
  1. Always use the right tools: A sturdy grill brush with metal bristles is your go-to. Or, if you’re going bristle-free, a scraper or a brush with coiled wires works too, depending on the material.
  1. Stay consistent: You don’t have to go all out with a deep clean every single time you grill… but really, a quick brush after each cook will save you from a bigger cleanup later on. Think of it like flossing – but for your grill!
  1. Oil your grill grates: After cleaning, lightly coat your grill grates with oil to prevent future food from sticking. This creates a non-stick surface and helps prevent the grates from drying out and rusting – a win-win!
  1. Stay safe: When you’re using cleaners, especially on materials like cast iron, be mindful of what you’re using. Stick to non-toxic cleaners or opt for natural methods like vinegar or baking soda.

K​​eeping your grates clean is key to their longevity. But sometimes, wear and tear means you’ll need a replacement.

If your grates are beyond saving, it might be time to browse our collection of grill parts to get your grill back to peak performance.

The Best Way to Clean Grill Grates by Material

Now that you’re armed with our pro tips, let’s dive into the best way to clean grill grates based on what they’re made of.

Different grill grates come in all shapes and materials and require different care. Cast iron, stainless steel, and porcelain grates each have their own set of cleaning needs – and knowing how to treat each one is key to keeping them in perfect grilling condition. 

Cast Iron Grill Grates

Ah, the trusty cast iron. Cast iron grill grates are durable and can retain heat so well – but they do need a little extra TLC.

How to Clean Cast Iron Grill Grates

  1. Preheat the grill: Just like we mentioned earlier, a hot grill makes for easier cleaning (just be careful not to burn yourself!). Once it’s hot, use your grill brush to scrape off any food particles.
  1. Use a gentle cleanser: Avoid harsh chemicals – cast iron grates can rust easily. Stick to warm, soapy water or a paste of baking soda and water for any tough spots.
  1. Dry immediately: Water is your enemy here. After cleaning, dry the grates thoroughly to prevent rust.
  1. Re-reason with oil: After drying, coat your grill grates in a thin layer of oil to re-season them and keep them non-stick.

Alternative Method for Cleaning Cast Iron Grates

Cast iron grates love heat, but they can rust, you know. This method gives them the TLC they deserve:

  1. Create a paste using 1 ½ cups of baking soda, ¼ cup dish soap, and ¼ cup white vinegar. It should be frothy and sticky.
  1. Paint the grates with the paste and let it sit for 8-12 hours (overnight works, too).
  1. Use a nylon-bristled brush or sponge to remove grime.
  1. Dry completely and rub the grates with oil to prevent rust. Fire up the grill after coating to lock in that seasoning!

Stainless Steel Grill Grates

Stainless steel grill grates are the low-maintenance champs of the grill world. They’re resistant to rust and corrosion, making them easier to clean. 

… But don’t skip the cleaning entirely!

How to Clean Stainless Steel Grill Grates

  1. Preheat and scape: Same process here – get that grill hot and give it a good scrub with your grill brush.
  1. Spot clean with vinegar: For any stubborn grease or debris, a little bit of vinegar on a cloth can go a long way. Wipe down the grates and let them shine!
  1. Polish for that sparkle: If you’re feeling fancy, buff your stainless steel grates with a microfiber cloth to make them look brand new.

Alternative Method for Cleaning Stainless Steel Grates

  1. Mix a paste of 1 ½ cups of baking soda and ½ cup of water. The consistency should be thick enough to stick to the grates.
  1. Cover the grates with the paste using a sponge or brush and let it sit for a few minutes. 
  1. Crumple a piece of aluminum foil into a ball and scrub each grate wire thoroughly.
  1. Rinse with water, and voilà! Shiny, clean grates ready for grilling action.

Porcelain Grill Grates

Porcelain-coated grill grates are perfect for even cooking… but they can chip if you’re too rough with them – and you wouldn’t want porcelain chip in your food, would you?

How to Clean Porcelain Grill Grates

  1. Be gentle: Use a soft grill brush or nylon brush to clean the grates – this is to avoid metal bristles that can scratch or damage the coating.
  1. Use baking soda: For tough spots, use a baking soda paste (baking soda + water) and gently scrub, scrub, scrub! 
  1. Rinse thoroughly: Make sure to wash off any cleaner residue (only use the non-corrosive kind) to keep your food safe and delicious.

Alternative Method for Cleaning Porcelain or Enamel Grill Grates 

  1. Remove the grate and place it on a flat surface.
  1. Wet the grill grate and sprinkle some baking soda over it. Let it sit for 10 minutes.
  1. Grab a damp scour sponge and scrub away!
  1. Rinse thoroughly, and you’re good to go!

If your porcelain grates are beyond repair, or if you’re just looking to upgrade, check out our range of replacement grill parts for over 280 brands. Whether you need a fresh set of grates or other grill parts, we’ve got your grill covered!

Grill Cleaning Hack: How to Skip the Scrubbing

If you’d rather skip the baking soda, vinegar, and elbow grease, we’ve got an alternative for you – but it’s only if you’re in no rush for instant gratification!

  1. In a large trash bag, mix 2 cups of white vinegar and 1 cup baking soda. The mixture will instantly begin to foam – that’s meant to happen!
  1. Remove the cool grates from your grill and place them inside the bag, seal tightly, and leave them overnight (or at least 8 hours).
  1. Rinse off the grates, and most of the grime should fall away. Scrub any stubborn spots with aluminum foil or a sponge.
  1. The next day, rinse, dry, and return to the grill.

Whether you’ve got cast iron, stainless steel, or porcelain grill grates, keeping them clean is the best way to ensure your grill lasts and your food stays tasty. So go ahead and preheat the grill, use the right brush, and take care of the grates according to their material. 

And remember: a little regular maintenance goes a long way!

FAQs for Grill Grate Cleaning

How often should I clean my grill grates?

Quick answer: brush them off after each grilling session! For deep cleaning, if you’re a frequent griller (think once a week or more), aim for every 4-6 months. If you’re more of a casual cookout type, once a year will do the trick.

What happens if I never clean my grill grates?

Ah, you really don’t want to go there! Neglecting your grates means rust, decay, and pretty gross-tasting food. Plus, who wants their steaks flavored with old grease? Regular cleaning keeps your grates in top shape and your food delicious.

How can I remove rust from my grill grates?

Surface rust? You’ve got this! A good scrub or seasoning with oil can handle most rust situations. But if your grates are deeply rusted or pitted, it’s time to say goodbye and get a replacement. Don’t grill on badly rusted grates – it’s just not worth it!

When should I replace my grill grates?

There comes a time when even the best grates need retiring. If the rust won’t budge, your porcelain coating is chipping, or they just refuse to clean no matter what you do, it’s probably time to swap them out. Keep an eye out for these signs and treat your grill to some shiny new grates!

How do I remove carbon buildup from my grill grates?

Whether you’re using baking soda, grill cleaner, or even steam, all these methods will help you tackle those burnt-on bits. Just follow our cleaning tips, and you’ll be back to grilling in no time!

Keeping your Traeger grill clean is key to making sure it works well and keeps delivering those delicious, smoky flavors you love. 

Luckily, with just a few easy-to-follow steps and a little know-how, you can get it done in no time. 

In this guide, we’ll show you how to clean a Traeger grill and get into the nitty-gritty of cleaning key components like the pellet system, grates, and grease traps

Let’s get started!

Should You Really Bother Cleaning Your Traeger Grill?

You might be thinking, “I just used it to grill up some burgers. Do I really need to clean it already?”

The answer is a big, fat yes! 

Leftover grease, ash, and food particles can build up over time. This can mess with your grill’s performance, affect the taste of your food, and even lead to safety issues like grease fires. 

No one wants their next burger tasting like last week’s BBQ chicken, right? Regular cleaning not only keeps your grill in top shape but also helps your food taste amazing and fresh every time.

Plus, it’s a great way to prevent rust and extend the life of your Traeger!

If you notice your grill’s looking a little worse for wear, you might need to replace a part or two. No worries – you can find all the parts you need at Appliance Factory Parts.

When Should You Clean Your Traeger Grill?

Before we get into the cleaning process, here’s a quick rundown of when you should be cleaning your Traeger grill:

  • After each use: Wipe down spills and scrape off any leftover bits on the grill grates.
  • Every 2-3 cooks: Do a deeper clean inside the grill.
  • Every 3 months: Clean the grill’s exterior (more often if you don’t use a Traeger grill cover!).
  • Every 6 months: Clean out the grease chute and the pellet hopper.

Now, let’s get to the fun part – how to do all of the above!

How to Clean Traeger Grills Grates in 3 Easy Steps

First things first – let’s talk grates. After every BBQ session, they’re going to have some leftover food and grease, and if you don’t clean them, that gunk is just going to build up

And let’s be honest, no one wants a dirty grill ruining a good steak!

Here’s how to keep your Traeger grill grates clean:

  • Step 1: Warm grates are easier to clean, but make sure they’re not hot – no one needs grill burns!
  • Step 2: Traeger recommends staying away from wire brushes as they can damage the ceramic coating. Instead, grab a nylon cleaning brush.
  • Step 3: Wipe down the grates with a cleaning cloth or paper towel. For stubborn bits, try a mix of distilled white vinegar or baking soda with water to loosen things up.

Pro tip: Feeling adventurous? Some people swear by scrubbing grates with half an onion or lemon – gentle on your grill and super effective!

How to Clean the Traeger Pellet System and Hopper

Don’t forget the behind-the-scenes heroes of the pellet system: the hopper, auger tube, and firepot. 

Whether you’re using a Traeger Redland or a Mesa Pellet Grill, the pellet system is the heart of your Traeger pellet grill – and it needs a little TLC to keep those smoky flavors coming. 

Here’s how to keep it in top shape:

  • Pellet hopper: First, turn off and unplug your grill. Then, make sure to empty the pellets from the hopper after every use – leftover pellets can absorb moisture and jam up the auger tube. Now, give it a quick vacuum to get rid of any sawdust.
  • Auger tube: Check for jammed pellets that could block the flow by cleaning it out once in a while. If things are looking stuck, clean it out to keep everything moving.
  • Firepot: Scrape out ash and debris after each use for a clean burn, and vacuum out the cold ashes or sawdust. Double-check that the firepot fits back in properly – make sure the grill is cold first!  

Need tools for this job? Check out our grid cleaning brushes, Venturi cleaning brushes, and basting brushes to get the job done right.

Don’t Forget to Clean the Grease Channels, Too!

While the hopper handles the pellets, the grease channels make sure you don’t end up with unwanted flare-ups. So make sure to clean them out regularly to prevent blockages.

If your grill has a chimney, don’t forget to clean it out, too.

Pro tip: Keep an eye on these areas to avoid grease fires and help extend the life of your Traeger.

How to Clean the Grease Trap on a Traeger Grill

The grease trap does all the dirty work, catching drips and grease. But if you forget about it, you’re in for a nasty surprise.

Clogged grease traps can cause flare-ups and smoke. That’s something you definitely don’t want during your cookout! 

So, make it a habit to empty the grease trap regularly. Don’t wait until it’s overflowing!

  • Clean it out with warm, soapy water or a grill degreaser, and if you’re using a liner, swap that out, too.
  • When you’re done, wipe down the grease trap with a paper towel or cleaning cloth. Use a mild degreaser or vinegar solution to tackle any stubborn spots.

Tip: If you’ve got a newer Timberline or Ironwood model, don’t forget to clean the grease governor and ash keg!

How to Deep Clean Your Traeger Grill

Every couple of months (or more often, if you’re grilling fatty foods like pork belly), your Traeger is going to need a deep clean to keep it running like new. 

It’s not as hard as it sounds – we promise!

Here’s how to deep clean your Traeger grill:

  • Step 1: Remove the grill grates, drip tray, and heat baffle. Take out the firepot for a really thorough clean.
  • Step 2: Use a shop vac to clean out the barrel, fire pot, and under the heat shield. Get rid of any ash or food residue.
  • Step 3: Spray down the inside and outside of your grill with a non-chemical cleaner. Let it sit for a few minutes, then wipe everything down with a paper towel or cleaning cloth. This helps remove grease, ash, and grime buildup.
  • Step 4: Once everything is spotless, put the grill back together – reinsert the drip tray, grates, heat baffle, and firepot.

Cleaning might not be the glamorous part of grilling, but it’s definitely one of the most important. Keeping your BBQ grill clean doesn’t just make your food taste better – it also helps it last longer and ensures you avoid any greasy flare-ups while cooking. 

The good news? It’s not that hard if you know the right steps!

We’ll walk you through cleaning a grill properly – from gas, charcoal, and propane to pellets and smokers. Plus, we’ll share tips on getting rid of rust and keeping your BBQ grill looking (and working) like new!

Grill Cleaning – What You Need and How Long It Takes

If you give your grill a quick clean after every use (and trust us, it’s worth it), you’ll be done in 5 to 10 minutes tops. For those deeper, seasonal cleanings, set aside 30 minutes to an hour, depending on your grill type.

As for what you’ll be needing: when it comes to the best way to clean a grill, having the right tools makes all the difference! 

Here’s a quick rundown of what you’ll need for effective grill cleaning:

  • Grill brush: A good wire brush is excellent and the classic go-to for scraping your grates. Looking for a DIY option? Grab a curly steel scour pad or even ball up some aluminium foil. Just use a pair of 12-inch tongs, and you’ve got yourself a makeshift grill brush!
  • Scraper tool: Got stubborn gunk inside your grill? A scraper is a real lifesaver. Don’t have one handy? No problem – any painter’s multitool can get the job done, too.
  • Dish gloves: Between the hot water, soap, and sharp edges inside the grill, protecting your hands is a smart move. Grab a sturdy pair of dish gloves to avoid cuts and irritation.
  • Scour sponge: A good scour sponge is tough on stuck-on grease but gentle enough that it won’t scratch up the more delicate parts of your grill. 
  • Dish soap or degreaser: For everyday grease, a clear dish liquid should work wonders. If you’re dealing with some seriously baked-on grime, try an all-purpose cleaner – it works wonders (just make sure to buy one that is safe for food surfaces!).

Cleaning a Grill – 6 General Cleaning Steps

A Quick Go-To Checklist If You’re in a Hurry:

✅ 1. Safety first – make sure the grill is cool before you get started. But if you’re cleaning after cooking, leaving it slightly warm makes it easier to scrape off gunk.

✅ 2. Remove the grates, flavorizer bars, drip trays, and anything else that comes off. This will make cleaning much easier.

✅ 3. Grab a grill brush and get scrubbing to remove stuck-on food and grease from the grates and inside the grill.

✅ 4. Grill cleaner or soapy water works wonders. Use it to give everything a good scrub. Don’t forget to clean the inside of the grill, too!

✅ 5. Once you’ve scrubbed everything, rinse with water and dry the parts thoroughly to prevent rust.

✅ 6. Put everything back together, and voilà – your grill is clean and ready for the next BBQ!

How to Clean a Gas Grill

Gas grills are great for quick and easy cooking, but they do need some extra TLC when it comes to cleaning. 

Here’s how you can keep yours clean:

  • Burners: These tend to get clogged with grease and food particles. Take them out and scrub them with a wire brush to keep the flames even and reduce flare-ups.
  • Heat deflectors: These plates sit above the burners and catch a lot of grease – so be sure to give them a good scrub!
  • Grease trap: Don’t forget the grease tray underneath. Empty it regularly to avoid buildup, and clean it with warm soapy water.

If you see buildup on the grill hood, a quick wipe with hot, soapy water and a scour pad should clear it up – luckily, this doesn’t need to be done too often. 

While you’re at it, take a look at the burner ports. If any of them seem blocked (no flames where there should be), turn off the burners, close the propane tank, and use a wire poker (or a metal wire or cake tester) to clear any obstructions.

How to Clean a Charcoal Grill 

Charcoal grills have a simple design, but they can get pretty dirty after just a few uses. 

Here’s how to keep them clean:

  • Ash and leftover charcoal: After each cook, empty out the ash and leftover charcoal. This keeps your grill clean and ready for the next cookout.
  • Scrape grates and bowls: Use a wire brush to get rid of any stuck-on food or grease. If your grates are super dirty, a soak in soapy water will help.
  • Tackle residual ash: Before you start any deep cleaning, vacuum or brush out as much dry ash as possible. A shop vac works wonders for this!
  • Scrub it down: After clearing the ash, hose down the grill, both inside and out. Then, scrub the firebox and grates using hot water, a plastic scour pad, and some dish soap or a food-safe degreaser. If you’re using a degreaser, let it sit for about 20 minutes before scrubbing, then rinse everything thoroughly with hot water.
  • No hot coals and water: Never extinguish hot coals with water! This can create lye, which can damage your grill and even cause chemical burns. 
  • Prevent rust: Avoid leaving your grill out in the rain to prevent the rust from creeping in. If you see any, scrub it away and coat the grill with a light layer of vegetable oil to help protect the metal.

How to Clean a Propane Grill

Propane grills work just like gas grills, with the added bonus of needing to take care of the propane tank:

  • Turn off the propane: Make sure the propane tank is disconnected before you start cleaning.
  • Soak the grates and plates: Remove the grates and heat deflectors, and soak them in warm, soapy water while you clean the rest of the grill.
  • Burners and deflectors: Clean these just like a gas grill. Check for any leaks or loose connections while you’re at it.
  • Clean the venturi tubes: Remove and clean the venturi tubes with soapy water. Use a wire to clear any clogged holes, then rinse and let them dry before reassembling. 
  • Reassemble and connect: Once everything is dry, replace the parts and reconnect the propane tank. And now, you’re ready to grill again! 

How to Clean a Pellet Grill

Pellet grills need some special attention than your average charcoal or gas grill – but the flavor payoff is worth it! 

Since you can’t just hose down a pellet grill (too many electronics!), you’ll want to remove the grates and grease pan to clean them properly. Plus, wet wood pellets can expand, leading to dreaded auger jams – so definitely keep the garden hose away!

Follow these guidelines to be safe:

  • Empty the pellet hopper: After each use, empty out any leftover pellets. They can absorb moisture and cause issues down the line.
  • Clean the auger: The auger feeds pellets into the firebox, so make sure to keep it clean and free of jammed pellets.
  • Scrape the inside: These grills can get greasy fast, so give them and the smoker box a good scrub inside to remove grease and soot.
  • Grate cleaning: After every use, clean those cooking grates. Pellet grills don’t get super hot, so food debris tends to be stickier and more gummy than charred. Start with a grill brush, but if they’re really stuck, soak the grates in hot, soapy water for a bit then scrub them with a scour pad.
  • Grease pan: The grease pan needs attention after every session, especially after smoking fatty meats like brisket or pork belly. Built-up grease can lead to fires, and trust us, that’s a mess no one wants. While the pan is still warm (but not too hot), use a scraper to remove the gunk. If it’s not squeaky clean, give it a wash with hot, soapy water and a scour sponge. Just don’t forget to protect your hands with gloves!
  • Check the grease chute: Make sure the chute between the grease pan and the collection bucket isn’t clogged with food debris. A cheap wooden paint stirrer (or something similar) can help keep it clear. This is also a good time to empty the grease bucket hanging off the side of the grill.

How to Clean a Smoker

Smokers can get pretty dirty due to the long, slow cooking process. Follow these guidelines to keep them clean:

  • Wipe down the walls: Smoke can leave a residue inside, so give the walls a good wipe with soapy water after each use.
  • Clean the drip pans and ash traps: Grease and ash build up quickly in smokers, so empty and clean them regularly to keep everything running smoothly.

How to Clean a Rusty Grill

Got a bit of rust? Don’t worry, it happens to the best of us – but it doesn’t mean your grill is doomed!

Here’s how to bring it back to life:

  • Scrub the rust: Grab a wire brush or steel wool and get scrubbing. It might take a little elbow grease, but you’ll get there! Just be sure not to use steel wool on stainless steel grates – stick to a soft cloth or sponge for those.
  • Oil it up: After you’ve scrubbed away the rust, coat your grates with a thin layer of oil to keep future rust at bay.

Got a stubborn rust spot? Try one of these easy fixes:

  • Soda: Got some cola? Soak rusty parts in soda overnight – the phosphoric acid will help break down the rust. Then, rinse and scrub clean.
  • Lemon juice and detergent: Lemon juice is great at dissolving rust! Mix it with some powdered detergent to form a paste. Apply, leave it overnight, and scrub with warm water the next day.
  • Vinegar and baking soda: Mix baking soda and vinegar into a paste, apply it to the rust, and let it sit for 20–30 minutes. Scrub it off with a soft cloth and warm water, then rinse.
  • Commercial rust remover: If all else fails, grab a commercial rust remover and follow the package directions. Your grill will be rust-free in no time!

Cast iron cooking grids are a grill lover’s best friend, providing an ideal surface for everything from searing steaks to slow-cooking lamb.

But to get the best performance out of cast iron, a bit of regular maintenance is essential.

The good news? After the initial seasoning, it’s a quick 30-second task every time you grill.

First-Time Use

Start by washing your cast iron cooking grids thoroughly with mild dish soap. Rinse with hot water and pat dry completely with a cloth – don’t let them air dry or put them in the dishwasher.

Before you start grilling, season your grids to prevent rust and create a non-stick surface. Not sure how? We’ve got seasoning instructions for you below!

Porcelain Coating: A Quick Note

Many cast iron grids are coated with a matte porcelain enamel coating, making cleaning easier and reducing corrosion.

While some chipping may occur, it won’t affect performance. If rust appears, just use a good grill brush to remove it and re-season the grids.

Why Seasoning Cast Iron Grids Is Important

Like cast iron skillets, cast iron cooking grids need regular seasoning. Seasoning protects the porcelain coating, reduces food sticking, and prevents rust. Properly seasoned grids will also keep your cast iron stove grates looking rich and black over time.

How to Season Cast Iron Cooking Grids – Easy Steps!

For the first seasoning, use solid unsalted vegetable shortening, although grape seed or olive oil will work. Spread a thin coating of oil across the entire surface of the cast iron grids with a paper towel. You can also melt some vegetable shortening in microwave and brush on using a silicone basting brush.

Make sure you cover every corner. Avoid using salted fats like margarine or butter. Non-stick sprays are also less effective as they burn off at low temperatures.

Preheat your grill on HIGH for about 10 minutes, then turn burners to MEDIUM with the lid closed for another 30 minutes. Turn off the grill and let the grids cool inside. They’re now seasoned and ready for grilling!

Re-seasoning Tips: Periodic re-seasoning with unsalted vegetable shortening or oil will keep your cast iron grids in great condition. Over time, the grids will build up a durable non-stick layer, making maintenance easier with each use.

Maintenance – Every Time You Grill!

Skip the burn-off right after you grill; leave the cooking residue on to act as a protective layer. Do the burn-off just before you start grilling again. Brush off any residue with a grill brush, and you’re set to go.

Storing Your Cast Iron Grids

If you won’t be grilling for an extended period, we recommend you lightly season the grids before storing them in a dry place. This will help prevent any rust buildup, so they’re ready for action the next time you fire up the grill.

The Cast Iron Advantage: Unmatched Performance with a Little Extra Care

When it comes to barbecue grill grids, cast iron is in a class of its own. Its heat retention and durability make it ideal for everything from creating rich sear marks on steaks to grilling delicate vegetables.

Plus, when properly seasoned, cast iron grids offer an exceptionally non-stick surface that improves over time.

Although they require a bit more upkeep than stainless steel or porcelain-coated wire grids, the benefits of cast iron are well worth it for any grill enthusiast. With the right care, your cast iron cooking grids will reward you with years of peak grilling performance.

High-heat infrared gas grills are…pardon the pun…hot! Fans say they take grilling to the next level. But, just exactly how are they different from traditional gas grills? And are they really worth the hype?

Both infrared and traditional gas grills use propane or natural gas as fuel, but they cook differently. In a traditional gas grill, flames from the burner heat the grilling surface and circulate hot air around the food to cook it using a combination of conduction (direct contact with the grill grid) and convection (hot air circulation). While traditional grills work well, they often don’t reach high enough temperatures for a proper sear, and the circulating air can dry out your food.

How infrared Grills Work: The Science Behind the Sear

An infrared grill cooks by radiant heat – the type of heat produced by the sun, and the same glowing, red, energy waves produced in a charcoal or wood fire. In an infrared grill, an emitter made of ceramic, stainless steel or glass, is either incorporated as part of the gas burner or positioned directly above it.

Flames from the burner heat the emitter, which radiates infrared energy waves. These waves directly penetrate the food to cook it. The emitter also dramatically reduces or eliminates the hot air convection effect, preventing food from drying.

Early infrared grills were known for their high-heat cooking abilities, excellent for searing, but they didn’t offer much flexibility for lower-temperature cooking. However, newer infrared models come with much broader temperature ranges, providing a wide variety of cooking options.

6 Benefits of Infrared Grilling

1. Juicier Food

Infrared heat cooks food quickly, locking in moisture and juices. Studies show that infrared-cooked foods are 30% heavier than those cooked on traditional grills due to moisture retention.

2. Steakhouse Results

The high heat of an infrared grill (up to 1,000 degrees or more) creates a restaurant-quality sear, something difficult to replicate on most traditional grills.

3. Saves Time and Money

Infrared grills are highly efficient, using 30% to 50% less fuel than traditional gas grills. They heat up in just 3-5 minutes and cook food twice as fast, saving both time and money.

4. Grill in Any Weather

Unlike traditional gas grills, which lose heat in cold or windy weather, infrared grills maintain consistent temperatures regardless of conditions, even when the lid is opened.

5. Easy to Clean

Due to the high heat, grease drippings are vaporised before they can reach the grease tray, resulting in less maintenance and easier cleanup.

6. More Affordable Options

After the original infrared grill patent expired, more manufacturers began offering them, resulting in lower prices. Today, second- and third-generation infrared grills are more affordable, with some models using standard gas burners combined with metal or glass emitter plates.

Types of Infrared Grills: Choose the Right Configuration for You

Infrared grills come in various configurations. Some are entirely infrared, while others combine infrared searing burners with traditional burners for versatile cooking.

Many grills feature a searing station or infrared side burner designed specifically for high-heat searing. If your grill has a vertical rotisserie burner at the back, it’s likely infrared as well.

Learning Curve with Infrared Grills

It takes a little trial and error to master infrared grilling. Because food cooks faster, timing on recipes may have to be adjusted. And, when you’re cooking at these high temperatures, you definitely don’t want to walk away from the grill, or you may come back to hockey pucks.

But with a little practice, an infrared grill is just as easy to use as a traditional grill and yields very tasty, restaurant-worthy results.

Great grilled food starts with a quality cooking grid. It’s the secret to perfect sear marks, that mouthwatering crusty exterior, and the smoky flavour everyone craves. If your grid is rusted, warped, or burned through, it’s time for an upgrade.

Here’s everything you need to know to choose the best replacement!

Why is a Good Cooking Grid Important?

Grilling relies on three types of heat energy:

  • Radiant heat – Infrared energy from your grill excites food molecules, creating heat.
  • Convection heat – Hot air circulates inside the closed grill hood to cook evenly.
  • Conduction heat – Direct contact between food and the cooking grid creates those signature grill marks.

Your cooking grid is responsible for conduction cooking. It’s what transforms regular cooking into grilling magic.

Cooking Grid Materials: Which One is Right for You?

Most cooking grids are made from one of five materials. Each type offers unique advantages in durability, heat retention, maintenance, and price.

1. Chrome-Plated Steel Grids

  • Pros: Affordable and easy to clean.
  • Cons: Thin, widely spaced rods don’t hold heat well and can warp or rust over time.
  • Best for: Occasional grillers on a budget.

2. Porcelain-Coated Steel Grids

  • Pros: Porcelain prevents sticking, resists rust, and is easy to clean.
  • Cons: The coating can chip, leading to rust.
  • Best for: Budget-friendly grilling with a slightly longer lifespan than chrome.

3. Cast Iron Grids

  • Pros: Excellent heat retention for deep sear marks; highly durable.
  • Cons: Require regular seasoning to prevent rust and maintain performance.
  • Best for: Grill enthusiasts who value performance and are willing to do some maintenance.

4. Porcelain-Coated Cast Iron Grids

  • Pros: Combines the heat retention of cast iron with the low-maintenance benefits of porcelain.
  • Cons: Prone to chipping if handled roughly.
  • Best for: Those who want the performance of cast iron without frequent oiling.

5. Stainless Steel Grids

  • Pros: Durable, rust-resistant, and easy to clean. Great heat retention for a perfect sear.
  • Cons: The most expensive option.
  • Best for: Premium grilling with minimal upkeep.

How Grid Design Impacts Grilling

The shape, thickness, and spacing of the grid bars also play a key role in grilling performance:

  • Thicker bars retain more heat and create bold sear marks.
  • Tightly spaced grids are ideal for delicate foods like fish and veggies.
  • Widely spaced grids work best for larger cuts of meat.

Hot Tip: Choose wider bars for more pronounced grill marks and enhanced searing.

3 Quick Maintenance Tips for Longer-Lasting Cookings Grids

  1. Clean after each use to remove grease and debris.
  2. Preheat the grid before cooking to kill bacteria.
  3. Oil the grid lightly to prevent sticking and rust.

Hot Tip: To make those iconic, cross-hatch grill marks, rotate food a quarter turn halfway through the cooking time required on the first side. Then repeat the process on the second side.

Find the Perfect Replacement Cooking Grid

A little ongoing maintenance will help preserve your cooking grid for years to come, no matter the material or configuration. Whether you’re grilling filet mignon or a humble hot dog, it’s important to start with a clean, hot, oiled cooking grid.

If your cooking grid has seen better days, it’s time for a replacement. Whether you prefer cast iron for superior searing or stainless steel for durability, there’s a grid for every grilling style.

Igniters are responsible for lighting the gas in the grill’s burners. When they work well, igniters make grill-lighting as eay and convenient as pushing a button or turning a dial.

But, not surprisingly, considering they do their job in an abusive environment of high heat, acidic meat drippings, and corrosive weather conditions, sometimes things go wrong. In fact, igniter failure is a common complaint – and source of frustration – for gas grillers.

True, you can usually light the grill by manually inserting a long match or lighter through a hole in the base of the grill. But, replacing the igniter is an easy and relatively inexpensive fix that will have you back in business faster than you can say finger-lickin-good.

How Grill Igniters Work

Grill igniters use a spark to ignite gas within the burners. The magic happens behind the control panel, where a piezoelectric crystal generates an electric spark when activated. This spark travels through a wire to an electrode tip inside a collector box, where it ignites trapped gas, which then lights the burner.

Types of Grill Igniters 

  1. Piezo Igniters: Produce a single spark with each push or turn.
  2. Battery-Operated Igniters: Generate multiple sparks with a “click, click, click” sound, offering more reliable ignition.
  3. Hot-Surface Igniters: Found in premium grills, these rods instantly heat to ignite gas and are resistant to corrosion, offering exceptional durability.

 

Troubleshooting Common Igniter Issues

  • First, check the battery – it’s often the culprit. To replace a dead or corroded battery, simply unscrew the igniter button. Pop in a new AA battery and reposition the unit.
  • If that doesn’t work, check the flexible wire. Are the connections tight?
  • Is the wire’s electrode tip aligned properly within the collector box? Is the electrode corroded? Try sanding the tip with sandpaper or wiping it with alcohol.
  • Is the collector box cracked? If so, it must be replaced. If not, try sanding the interior of the box.

 

When to Replace Your Igniter

If none of these easy fixes works, it may be necessary to replace the igniter unit. But before you do, try one more test. Manually light the grill with a match.

If it lights, the problem is likely the igniter. If it doesn’t light, the issue may actually be a clogged or dirty burner. Clean the burner and test the igniter again. If the grill lights, there’s no need to replace the igniter. If it doesn’t, a new igniter will probably do the trick.

 

Safety Tip: If a grill ever fails to light, always wait 5 minutes before attempting to relight it to allow the gas to dissipate.

metal-heat-diffuser

Think a high-BTU burner is the secret to the perfect sear on your steak? Think again. The real MVP of your grill’s heat control is the heat diffuser.

It’s a common myth that the higher a grill’s BTU rating, the more powerful it is. But, it’s really the design of the diffuser system together with the burner that determines how hot the grill can cook. A well-designed diffuser system can crank out more heat on a lower-BTU grill than a poorly designed system on a mega-BTU unit. That saves gas and money.

Heat diffusers are like middle children. They’re sandwiched between the burner and the cooking grid, and they’re often overlooked. But, they’re vital to your gas grill’s cooking performance and deserve some attention.

So, let’s dive into why heat diffusers are essential, the different types, and how to keep them working their magic.

The Mojo in the Middle

Heat diffusers have been used for ages – probably since right after people discovered food tastes better cooked over an open fire. Ancient civilizations realized that by putting stones, rocks or balls made of clay into the fire, they could increase the heat, spread it over a larger area, and make it last longer. Their food cooked better, too.

A barbecue grill works the same way. The burner generates the flames, and the diffusers hold, radiate and distribute the heat for better, more even cooking. Diffusers can bring heat to all areas of the cooking surface, beyond where the burner flames reach.

So, How Do Heat Diffusers Work?

Depending on the grill brand, diffusers might also be called heat deflectors, heat distributors, flame tamers, burner shields, heat plates, vaporizers, or even flavorizer bars. Whatever the name, diffusers perform 3 important functions to make barbecuing better.

  • They distribute heat evenly across the entire grilling grid, preventing hot and cold spots. With a good system, you won’t have to constantly rotate food around so it doesn’t burn.
  • They create a barrier to protect the burner from dripping grease, food juices, acidic marinades, and sugary sauces. These drippings could corrode or clog burners, and cause flare-ups.
  • Diffusers catch and vaporize food drippings to add smoky barbecue flavor to food.

The 3 Types of Heat Diffusers

Here’s a breakdown of the three main types of heat diffusers:

lava-heat-diffuser

Lava rocks are craggy, reddish brown, irregularly shaped pieces of volcanic rock dotted with tiny holes. They were popular on early gas grills, but are less common today. The rocks sit on a rock grate an inch or two above the burner and a few inches below the grilling grid.

They hold and reflect heat well, last long, and are inexpensive. Since they are porous and absorb grease, some believe they create more flavorful smoke. Downsides: they take longer to heat up, and because they’re not uniformly shaped, grease can drip through the gaps between the rocks and reach the burner, causing flare-ups, hot spots, corrosion and clogs.

ceramic-heat-diffuser

Ceramic diffusers are made of light-colored, heat-retaining ceramic material like the firebrick found inside many pizza ovens. They can be formed into pillow-shaped briquettes, rounded pucks, thin rods, or perforated flat tiles. Aligned edge-to-edge in a single layer, they can protect the burner better and distribute heat more evenly than lava rock. But, there may still be little gaps for grease to slip through and flare up when it hits the burner. Ceramic diffusers last a long time and are relatively inexpensive.

metal-heat-diffuser

Metal diffusers are most common today. Stainless steel or porcelain-coated steel is formed into inverted-V tents, accordion-folded sheets, or flat plates. The metal heats up fast so the grill is ready for cooking very quickly. The angled diffusers channel grease away from the burner into a drip pan in the base of the grill. Though this virtually eliminates flare-ups, some argue it generates less smoke and flavor. These are also more expensive than other types of diffusers.

How to Clean Your Heat Diffuser

To clean ceramic briquettes, flip them over so the soiled side is toward the burner. Turn the burner to high for about 15 minutes and let the grease burn off. If they are especially dirty, use a stiff brush to remove caked-on residue before burning. The process can be repeated whenever grease builds up.

Lava rocks are cleaned the same way. It’s just a little trickier to get the grease out of the nooks and crannies. Also, because they’re porous, lava rock should be cleaned before a grill is put into storage or unused for a period of time, or they can get moldy.

Soak metal diffusers in a tub of soapy water. Use a grill brush to scrape excess residue off stainless steel diffusers. But, use a nylon scrub pad on porcelain-coated metals or they’ll scratch.

When to Replace Your Diffuser?

Replace lava rock and ceramic briquettes when they are crumbling or the accumulated grease is hard to burn off. Replace the rock grates if they are rusted, or warped and don’t sit evenly.

On metal diffusers, areas of rust or burned-through metal, are signs they should be replaced.
