Bilt Hamber Auto-Wash is a new technology, highly powerful, environmentally friendly car shampoo, formulated to allow you to effortlessly and effectively clean your paintwork before waxing. Auto-Wash is anti-corrosive and suitable for bare steel also, ideal for owners of older vehicles which may have stone chips or exposed areas of mild steel. This is also an advantage in modern cars where the entrapment of corrosive elements carried by some detergents in folded seams accelerates the corrosion process.
