18" Plastic Brush with brass bristles on both sides, so this brush actually does double duty! A grill brush is the one tool you will use EVERY time you cookout! Look for one that is going to last a while, like this one. Usually, larger heads on grill brushes means less work on your part and is more effective in cleaning the entire cooking surface, faster. Also, plastic handle grill brushes do not weather as quickly as wood. The scraper should NOT be used on porcelain cooking grids. The stainless steel bristles are an effective material for all cooking grid surfaces.
