How to Clean a Gas Grill Properly from Start to Finish

There’s nothing quite like the smell of barbecue or the taste of perfectly grilled meat. But your grill won’t do you any good if it’s dirty or not working. By learning how to clean a gas grill the right way, you can extend the life of your grill and keep it from accumulating. The process is easier than you think and doesn’t take too much time. Follow this step-by-step guide to get your grill looking as good as new.

What Do You Need to Clean Your Grill?

To deep-clean a gas grill, you need to first get a few materials ready. Although there are several methods of cleaning a gas grill, some methods are more effective than others. Some people want to know how do you clean a gas grill with vinegar, but vinegar isn’t the best choice. It might be environmentally-friendly, but it’s not always effective enough to get your grill clean.

For our method, you need all of the following materials:

  • Gloves
  • Grill brush
  • Cleaning rags
  • Putty knife
  • Soap and water

Although gloves aren’t mandatory to clean a gas grill, they are recommended. Grill cleaning is a messy job and could leave your hands covered in black soot. You can save yourself a mess by wearing gloves.

It’s also worth mentioning that you can use paper towels instead of cleaning rags. However, paper towels are less sturdy and tend to fall apart.

How to Clean a Gas Grill

Grill Brush and WaterAre you ready to get started? Now that you have your materials, it’s time to get cleaning. Keep in mind that you don’t need to give your grill a thorough cleaning after every use. If you’re wondering how often should you clean a gas grill, there’s a simple answer. Every few months, your grill deserves a cleaning. If you barbecue frequently, then you should clean the grill well every month.

When the time comes to clean, you should follow these steps:

1. Get Your Supplies


Collect all of your supplies and place them near your grill. Depending on where your grill is located, you may want to move everything to a more convenient location. You need to be able to access the area behind your grill, so it may be too close to a wall for you to clean.

2. Turn the Gas Off and Remove the Grates

Before you do anything, you need to make sure the gas is off. To be extra cautious, you can completely detach the gas tank from your grill. Failing to turn off the gas puts you at risk, so a little extra caution goes a long way. Once the gas is off, you can remove the grill grates. Take out each one and lay it on the ground.

Pro Tip: Don’t try to clean your grill on the same day you use it. Instead, wait until you haven’t grilled for a day. This means that the grates won’t be hot.

3. Scrub the Grates and What’s Underneath Them

Take your grill brush and scrub the grill grates with force. Some of the particles might be stubborn, so you need to use elbow grease.

Because every model of gas grill is different, it’s impossible to say what’s under your grill grates. However, most models have some type of covering for the burners. If your model has heat tents, lava stones, or ceramic briquettes, take them out of the grill and clean them with your brush.

4. Clean the Burner Tubes

If your burner tubes are covered in debris, your grill won’t get as hot as it should. To keep your grill working, you should check the gas ports. Remove any debris that’s covering the ports and be certain that they are open. Using the brush, clean off the burner tubes with a gentle touch. Although this may seem like a simple step, it’s one of the most important parts of the process. Your burner tubes control the heat and can make or break your cooking experience.

5. Clean the Interior

While you have the grates out of the grill, give the interior a thorough clean. Use a wet cloth to wipe down the bottom and lid of the grill.

You might notice some peeling black flakes on the inside of your grill. Typically, these flakes are carbon and grease. To get rid of the debris, use your putty knife to scrape the affected areas.

6. Pull Out the Collection Tray

This is another step that depends on your model of grill. While most gas grills have removable collection trays, others have disposable ones. Look at your tray to determine what type you have.

The collection tray catches and stores grease from cooking. For this reason, the tray gets extremely dirty. Pull out your tray and use soap and water to clean it off. For grease that won’t give up, use hot water.  If it’s disposable, replace the tray.

Pro Tip: Don’t wash your collection tray in the sink. As the grease washes down your sink, it will collect and form a clog in your pipes. You can pour liquid gear into a can or bottle and throw it in the garage.

7. Clean the Exterior

Can you hose down a gas grill? Yes, but it wouldn’t do you much good. Because it’s exposed to the elements, smoke, and grease, the exterior of your grill gets dirty. It takes more than a spray of water to clean it. They sell grill cleaners, but soap and water work as well.

Take your rag and dip it in soapy water. Then, wipe down the outside of your grill. If there’s any soapy residue left on the exterior, use a wet rag to wipe the soap off.

8. Put the Grill Together

Propane GrillWait until all of the elements of your grill are dry. Once they are, you can begin to put your grill back together. This step is relatively simple, but you can always revert back to your grill’s instruction manual if you forget where something goes.

If you disconnected your propane tank, don’t reconnect it until you move the grill back to its original location. Once the grill is in place, connect the tank and leave it off.

Pro Tip: you don’t want to be surprised by a non-functional grill the next time you’re ready to barbecue. So, make sure your grill is working by turning the gas on and lighting the burners.

Do You Have a Clean Gas Grill?

Your grill deserves some TLC. When you cook on a dirty grill, your food will reflect that. Dirty grates and carbon flakes give your food a strange flavor. You won’t get the great flavor that you’re hoping for. Even worse, your grill won’t last for long. After only a short time, you’ll be in the market for a new grill.

When you treat your grill well, you’re rewarded with great barbecue. Before your grill is beyond a deep cleaning, give it some attention.
