How to Deoxidize Aluminum

Deoxidize aluminum to make things shine as if they were brand new.

Deoxidizing aluminum to remove stains will restore the naturally shiny finish and give old objects a quick facelift. Commercial treatments achieve the greatest results, but even simple processes conducted at home with inexpensive ingredients can revitalize oxidized aluminum. Deoxidizing aluminum is also a good choice for a science experiment that students can use to compare home remedies with more expensive store-bought cleaners or professional services. Seal the aluminum items after cleaning to prevent future oxidation.

Things You'll Need

• Oxidized aluminum surface
• Vinegar
• Baking soda
• Steel wool
• Car wax

Instructions

1. Dissolve 1 tablespoon of baking soda in 1 cup vinegar.

2. Apply mixture to oxidized surface with steel wool and rub vigorously until oxidation stains are removed from the surface.

3. Cover the surface with car wax to prevent aluminum oxidation reformation. Repeat as necessary.

Tips & Warnings

• To clean large surfaces, increase the vinegar and baking soda amounts proportionally as needed to accommodate the size of the project.

• Vinegar and baking soda may not remove especially deep or stubborn oxidation stains. In some cases it may be necessary to seek out a commercial solution to deoxidize aluminum.

• Avoid scrubbing with steel wool once the oxidation is removed, as this can scratch the exposed aluminum surface.
