This brush is great for cleaning Barbecue Grills. Nylon bristles are safe to ingest unlike competitors metal brushes. Stainless steel wire brushes can break off and get inside your food. Our nylon brush will clean more effectively as it uses all of the power of your cordless drill without the risk of contaminating your food with sharp metal wire. These brushes will not rust like metal bristle brushes. Do not use on warm surfaces.Cordless drill NOT included Drill NOT included
