Scotch-Brite bristle disc is designed to last longer than wire and other abrasive discs and works well on aluminum, brass, bronze, carbon steel, cast iron, stainless steel and other metals, and is used for general industrial, aerospace, automotive, metalworking, transportation and automotive applications. Under normal use, the flexible bristles remain safely in place and can achieve the desired finish using light pressure. - Scotch-Brite bristle disc, using ceramic abrasive grain and molded, flexible bristles, provides more surface contact than wire brushes and maintains abrasive property throughout the life of the disc. The fast-running disc removes paint, stains, adhesives, weld burns, rust, heavy oxides and surface contaminants from large areas.
