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. Simply broom, sponge or spray it on, straight from the bottle, or diluted with water. There’s never been an easier or faster way to clean intercoolers, turbo chargers, valve covers, radiators and bull bars. All your marine equipment like dinghies and side steps come up spotless too. And here’s more good news, Blitz Aluminium Cleaner doesn’t contain any Hydrofluoric Acid, so it’s it safer for you, your surfaces, and our environmental as well.
