Safer for the user and the environment. Has a high solvency and a high flash point. Safe to use on most hard surfaces including stainless steel, aluminum, rubber, glass, vinyl, and plastic. Will not etch, pit, fade, discolor or attack most surfaces. Spray or wipe it on, then rinse it off with water.
