This is a very Hi-Tech chemical designed to clean and deoxidize all metal surfaces without streaking, hazing, burning or damaging the surfaces. Removes scale, road film, most acid stains and even rust on chrome. It is the easiest and safest way to prep the metal before polishing. It really takes the elbow grease out of polishing! Can be used with most cream type polishes. After saturating a palm size terry cloth towel with Aluminium Deoxidizer (Step-1), you simply wipe on surface. Then apply Purple Metal Polish over the entire treated area and buff off to an incredible shine!
