The best way to clean a Weber barbecue involves using the right tools and products to ensure longevity and optimal performance. Start by heating the grill to burn off any excess grease and food particles. Once cooled, use a Weber stainless steel brush to clean the grates. For the exterior and the inside surfaces, use a specialised Weber grill cleaner, which is designed to handle grease and residue without damaging the finish.
