Description: Streak Master Bare Aluminum Cleaner and Brightener is the acid brightener of the future and the future is now. It has been developed to improve the safety of those using traditional bare aluminum brighteners (Hydrofluoric Acid Brightener); yet, still have a product that removes road film, grime, algae, scum, lime deposits, water line stains, oxidation, and brightens aluminum like a professional truck wash. Works just like the traditional aluminum cleaner and brightener (Hydrofluoric Acid Brightener) WITHOUT the negative hazards associated with that product. Forget the toxic and poisonous concerns and step up to new technology.
