Blast-Off removes concrete buildup and splatter with a powerful carboxyl containing organic molecule found in sugar cane and sugar beets. This dual-functional molecule dissolves buildup and splatter without damaging exposed steel, chrome, aluminum, or electrical components. It produces a foam that clings to vertical and overhead surfaces, and is considered by OSHA and federal DOT standards as noncorrosive and nonhazardous. Ready to use without mixing or diluting and packaged in 100% recyclable bag-in-a-box packaging, drums, and totes. Nox-Crete Products Group. 800-669-2738.
