How to Stop Polish on Aluminum from Oxidation

Updated April 17, 2017

Oxidation of aluminium causes the metal to corrode and begin to flake. The best way to prevent oxidation of aluminium is to apply a polish. However, after a while polish will begin to wear away in places, particularly if it is a cheaper polish. When this happens, the exposed aluminium will once again suffer from oxidation. To avoid this, use a rust-preventive polish or spray and reapply it regularly.

Rub the aluminium surface lightly with a scouring pad and warm water. Make sure to remove any traces of rust from the surface. Dry the aluminium thoroughly with an old towel.

Apply a rust-preventive polish, such as No-Wet, to the aluminium. Reapply the polish every six months, paying particular attention to areas where oxidation occurred previously.

You may also spray a rust-preventive treatment, such as WD-40, over the aluminium. The spray will prevent further oxidation from occurring. Reapply the spray as needed.
