How to Clean Oxidation From Aluminum Windows

Oxidation on aluminum windows appears as a dull gray-brown cast and white, powdery spots. Aluminum oxidation's white, powdery spots chemically bind to the aluminum to protect it from further corrosion. Although self-protecting, the oxidization on aluminum windows severely detracts from the visual appeal of a home. Window manufacturers add a protective coating to aluminum window frames to protect the window from exposure to air, salt and cleaning products to prevent corrosion. Unfortunately, not all windows have a protective layer and do corrode.
