If you want your food to taste better and your grill to last longer, always keep it clean. It’s a simple task that makes a world of difference. Food cooks better on a clean grate. It’s less likely to stick and won’t pick up foreign particles from past cooks. Also, the lifespan of your grill will be longer if you keep it clean. It’s best to clean a grill after it’s hot. Use a wire brush to scrape off any food stuck to the grate, and apply a thin coat of cooking oil to the racks with paper towel. This prevents the grates from rusting and the grill will be clean and ready to go the next time you want to fire it up.
