Gas grills are pretty low maintenance, but about once a year you should remove the grates, drip plates and burners to clean off the dirt and grease that invariably build up. This will add years to the life of your grill and keep it performing at its best. Between times you’ll want to wipe the outside surfaces with a soft cloth and warm soapy water before rinsing with clear water and drying thoroughly. Clean the bottom tray, or drip pan, frequently to get rid of grease that could cause flare ups. It’s easier to remove food residue from cooking grates before it dries, so do that with a grill brush or crumpled aluminum foil as soon as you finish cooking…but before the grill cools. Now, enjoy your Labor Day Cook out.
