There’s no better time of year than cookout season, and now is the perfect opportunity to put your barbecuing skills on show for all to see. But before you get down to grilling, ensuring you know exactly how to clean a barbecue grill is essential, and something that will prevent the spread of any harmful bacteria to your food and improve the taste of your food. 

Beyond hygiene, having good cleaning practices for your barbecue is also essential for the longevity of your equipment. Yes, that’s right, even the best gas grills need a helping hand in order to stay in pristine condition and prevent the build-up of carbon deposits on the grates, hood, flavoring bars, and burner tubes. This build-up not only looks unsightly but can lead to a growth of undesirable bacteria, and if left too long can spoil your grill for good. 

Now you know why learning how to clean a barbecue grill is so important, it’s time to spring into action. Take a look at our handy tips and tricks to get a sparkling clean grill so you can continue serving up delicious grilled foods without needing to worry about dirt. And if you want to continue grilling even into the colder months, why not check out our guide to the best indoor grills which give you all the flavor, without the smoke, for use inside your kitchen. 

How to clean barbecue grill grease and burners 

Step one
Remove the large dirt particles from your barbecue. Before you really begin thoroughly cleaning your grill, start off by turning the grill on for five to ten minutes so that any food debris is warm and easier to remove. Once you’ve turned off your grill and it’s cooled slightly, take a scraper (not a plastic one - a metal spatula is ideal) and gently push off any large food clumps or burned-on stains. 

It’s best to start at the top and work your way down so that dirt doesn’t fall where you’ve just cleaned. Be careful not to scratch too deeply during this step as you don’t want to remove any non-stick coatings the grill may have. It’s also important to remember that this step is just to remove large pieces of dirt, not every stain.

When it comes to cleaning the burners, brush the dirt off in the same direction as your burner holes to avoid getting even more dirt into them. If your burner has round holes, a toothpick or flossing stick is good for reaching inside.

How to clean the barbecue grill racks 

Step two
Take any removable racks out of your barbecue grill so that you can give them a good clean. It’s important to avoid using harsh chemical and strong cleansers on the racks, although it might seem like a handy shortcut. 

Instead, opt for a homemade cleaning solution such as water, baking soda and white vinegar, or dishwashing liquid. Failing that, some racks will even be suitable to pop into your dishwasher on the pot or pan setting. 

How to clean your barbecue grill drawer and grease pan

Step three
Gas grills are normally fitted with a handy drawer beneath the burners. This drawer is there to collect any debris and ash so that you can easily empty it out and wipe down the drawer. For the grease pan, this can be a messy job so be careful not to splash any grease over yourself. 

Once you’ve emptied the drawer and grease pan, take a ball of fine steel wool and a little bit of your gentle cleaning solution to give the inside of the gas grill lid and sides a wipe down.

How to keep your barbecue grill cleaner for longer

After deep cleaning your gas grill it’s unlikely you’re going to want to do it again anytime soon. Instead, help prevent future build up by trying out these easy techniques.

Steam clean your grill after using it 
Take a tin of water and place it on your grill for up to 30 minutes. The water will create a whole lot of steam and loosen any grime and grease that is clinging to the grill. This makes keeping on top of dirt a lot easier.

Line the debris drawer with tin foil  
The handy drawer beneath your burners is great for collecting cooking residues but it can be a real pain to clean. Save yourself a job and line the drawer with tin foil so that when it comes to cleaning time, you simply gather the foil up and place the entire thing in the trash. 

Use an onion on the grates 
We know this sounds strange but it is a proven tip for cleaning a barbecue grill. The acidity in an onion is a great natural cleanser for grates. The acidic properties will break down oils and grease making it easier to clean.
