Maintaining a gas grill is different than maintaining a charcoal grill, so here are some maintenance tips to make sure you’re on the right track. At the beginning of the season clean the burner and tubes, wash the grill, clean the cooking grates, and stock fuel levels. During the season while your grill is in use, continue to keep it as clean as possible. After the season clean everything all over again, wash the grill with a long-handled stiff-wire grill brush and warm, soapy water, and cover the gas line for storage. Happy grilling!
