Super tough plastic bristle brush, embedded with abrasive. Wears as it cleans, continually exposing fresh abrasive. The ideal tool to replace scrapers, wire wheels and chemical gasket stripper. Eliminates the danger of loose wires flying back at the operator. Safer for parts and the environment than hazardous chemical strippers. Use green on steel parts and yellow and white on aluminum parts for quick and safe removal. Bristles ride over surface cleaning contaminants without gouging surface.
