Grill grates and grids are the heart and soul of your Char-Broil grill. They see the most wear and tear, but there are steps you can take to keep them in top shape for as long as possible. For example, each time you fire up the grill, let the grill grates heat up under intense heat for at least five minutes. This will burn away food residue and make it easy to give it a quick brush before you grill your next meal. Adding a little oil to the grates will also make it more difficult for food to stick to the grates and grids. And, when they get too old and tired, replace them to ensure you have optimal grilling conditions.
