BIG RIG is a mildly alkaline, yellow, free-flowing powder, designed for manual or machine-washing of all transportation equipment. BIG RIG is a homogenous blend that will not cake or layer, and is readily soluble. BIG RIG is extremely free rinsing and is well supplied with sequestering agents so that it may be used with water of any hardness. BIG RIG is safe for use on all metals, paints, plastics and even rubber. Once in solution, BIG RIG quickly penetrates through dirt, grease and grime, leaving behind a streak free clean finish. BIG RIG generates a large volume of thick rich foam, which enables a very small quantity of diluted product necessary to clean any and all vehicles.
