Over time, even the best of the best charcoal grills will build up with dirt, ash, and rust. It’s therefore highly essential that you clean your grill regularly to make sure that they function and cook properly. If you use your grill frequently, make it an obligation to clean it at least twice after every grilling season. If you use it infrequently, one time is enough. Maintaining your grill will help it last longer and prevent food from sticking on the grate when preparing it.
