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.
Brush off any dirt and debris from the window with a dry, nylon scrub brush.
Pour equal amounts of water and white vinegar into a bucket.
Dip the scrub brush into the vinegar and water solution and scrub the aluminum window frames until the oxidation disappears.
Brush the window frames with a stainless-steel wire brush if the aluminum oxidation still remains.
Rinse the aluminum window frame with water and dry the surface with a rag.
Brush away any dirt and debris from the aluminum window frame with a nylon scrub brush.
