What you need to clean a gas grill

Grilling & Outdoor Cooking

How often you need to clean your grill depends on how often you use it and the types of foods you cook, but aim for roughly once after every four to six uses.

Cleaning a gas grill

Dirty grills aren’t just ugly — old stuck-on food can grow bacteria that transfers onto anything you cook and could potentially lead to food poisoning. Before you get scrubbing, you might be wondering what you need to clean a gas grill and how to clean one. 

The cleaning process will be easier if you invest in a few pieces of equipment, and they’ll last you long enough to make it worthwhile. Although cleaning a gas grill isn’t all that different from cleaning a charcoal grill, you have a few extra parts to worry about, such as the flavorizer bars and the burner tubes. 

How to clean a gas grill

Learning to properly clean your gas grill is vital, especially if you intend to grill regularly or you want your gas grill to keep going for years to come. A well-maintained grill is likely to stand the test of time and run more efficiently. 

Turn off the gas

Before you get started, make sure the grill is disconnected from the gas supply, whether you’re using a propane tank or your grill is connected to a household natural gas line. Either way, locate the gas supply valve and turn the knob or lever clockwise to shut off the flow of gas. This prevents the buildup of gas while you’re cleaning your grill, which could potentially lead to accidents, such as accidentally igniting the grill while working on it and burning yourself. 

Clean the grates

reusable cleaning gloves

The grates take a big hit when grilling food and are often caked in charred food and grease, so you need to pay them special attention. At this point, you might want to don some reusable cleaning gloves, as this will be a messy job. Remove the grates from your grill and brush them over with a steel grill brush to get rid of loose charred debris. Next, spray them all over with a grill cleaning spray — these are specially formulated to remove grease and other cooked-on grime from grills and do a better job than dish soap. Leave the spray to work for a few minutes to really tackle that grime before scrubbing with your wire brush once more. 

Barbi-Q Grill Cleaning Bricks

This should remove the bulk of the dirt, but if there’s still lots of stubborn stuck-on detritus, try pumice stone cleaning bricks, such as Barbi-Q Grill Cleaning Bricks. Finally, go over the grates with a clean, damp sponge to remove the last remnants of grime and set them aside to air dry. 

Clean the flavorizer bars

The flavorizer bars sit on top of the burner tubes to prevent them from getting clogged when grease drips down from the food on the grates and also help impart a smoky flavor as this grease gets heated by the flame from the burners below. This means they get covered in burnt-on grease and need a thorough cleaning. 

grill scraper tools

Remove the flavorizer bars, spray on a grill cleaning solution, and leave them for a minute or two. Next, scrape them to remove grease and other charred debris. Some grill brushes have built-in scrapers, otherwise you can buy grill scraper tools separately. Use a sponge to finish the cleaning job, then dry them with a cloth to prevent rusting. 

Clean inside the grill

Clean inside the bottom of the grill — the area sometimes known as the cookbox — using either soapy water or grill cleaning solution. Whichever you use, try not to get it on the burner tubes, because if they get wet, they can stop the grill from igniting until they fully dry out. If your grill has a removable drip tray, the easiest option is to remove this, scrape out the grease and clean it with a sponge and soapy water before drying and replacing it. 

Check inside the lid

Check the inside of the lid for any stuck-on charred food or residual grease that might have built up there while grilling with the lid closed. If you spot anything worth cleaning, spray on some more of your grill cleaning solution, leaving it for a minute or two to work its magic, then scrub lightly with the scourer side of a double-sided sponge to remove the built-up dirt. 

Spruce up the exterior of your grill

Although cleaning the outside of your grill isn’t essential, it will look better when clean and it makes sense to give it a once-over while you’re deep-cleaning the rest of your grill. Check whether your grill cleaner is suitable for use on the exterior of grills, or otherwise clean it with a sponge and soapy water. Finish by drying and buffing the outside of your grill with a cloth, especially if it has a stainless steel finish.
