Cleaning Oxidized aluminum

I have a fair number of aluminum pans at my beach house, and we occasionally have problems with saltwater corrosion of them (don't ask). What I do to clean them up is scour with a progression of grits of steel wool. I do it dry, but if you want to work vinegar into the mix, it won't hurt-maybe just decrease friction.

I also have to ask: Are you sure what you're seeing as oxidation isn't just the contrast between the passivation layer where the anodizing is gone and the darker vestiges of anodizing? If this is what's afoot, you might save yourself trouble and just keep DWing it until all the anodizing is gone. Or, scour it away by hand.
