Chemtech Blitz is a unique, concentrated acid-etch cleaner that removes corrosion and oxidation from aluminium, stainless steel and other bare metal surfaces, leaving a clean matt finish that is ready for high-gloss polishing. There’s never been an easier or faster way to clean intercoolers, turbo chargers, valve covers, radiators and bull bars and marine equipment. Unlike other cleaners, Blitz Aluminium Cleaner doesn’t contain any Hydrofluoric Acid, so it’s safe and good for the environment. Simply broom, sponge or spray it on, straight from the bottle, or diluted with water.
