Preheat the grill for 15 minutes on high heat to loosen any grease of leftover food.
Gather your cleaning supplies and make sure the gas supply is now turned off.
Remove the grill rates, and scrub with a grill brush or coarse cleaning brush dipped in a mixture of water and dish soap.
Once the grate has cooled, wipe down with a damp cloth to remove any residue.
Tip: Clean your grates while still warm after each grill use to remove any stuck-on food.
Use a rag or folded paper towel to lightly coat the grates with cooking oil or vegetable oil.
Remove anything covering the burners (think: metal heat tents, heat deflectors, ceramic briquettes, or lava stones) and brush clean using soapy water.
Remove burners and scrub with grill brush and soapy water. Do the same to the burner valve to remove any blockage.
Scrub away any debris from the burner hoods and bottom of the grill. Use a bristle brush or putty knife to remove any black carbon deposits caked on.
