ZAP's advanced formulation serves four applications in a single product, as it cleans, detects acid, neutralizes acid and protects against corrosion. As a cleaner, ZAP's foaming action penetrates and emulsifies dirt, grease and deposits. As a detector, ZAP contains a unique color indicator to show when all battery acid has been neutralized. As a neutralizer, additives in the formula increase the pH to a safer level. As a protector, ZAP provides a barrier against corrosion and the elements. It is excellent for use on batteries, terminals, cables, brackets and housings for everything, including fleets, golf carts, airplanes, boats, tractors, forklifts, construction equipment, floor scrubbers and more.
