This product gets its name from its zero rating in the three NFPA categories of flammability, health and reactivity. It is so safe it can be used to clean virtually any surface – metal, plastic, wood, fiberglass, rubber, fabrics, glass and more. Not only is it safe, but it strong enough to remove heavy dirt, grease, adhesives and just about any other soil or stain. It deodorizes as it cleans with a fresh pleasant fragrance. Can be used full strength or diluted as needed.
