Oxidation is the "dull" finish aluminum gets when it does not have wax or clear coat holding the finish shinny. It in itself is not bad for the aluminum. It is what an anodized aluminum airplane uses to keep the plane from corroding, with some success. However on the airstream areas around doors, sheets, and rivet heads often loose the clear coat that was applied on the sheets before assembly. Salt, water, dirt, etc work on those areas and cause the corrosion noted on the previous post. Washing the unit will help prevent that corrosion. We also wax it once clean.
If it is truly oxidation around the doors then the wax with "cleaning" or "polishing" will remove the oxidation. AND could with aggressive application likely open up more area without the clear coat and make a bigger problem.
