removing oxidation spots

[ljadon34]

Any recommendation on the best product that can remove oxidation spots on aluminums? Is there a product that leaves some sort of protective coating aside from removing these spots? Thanks.

Nevr-Dull or flitz is what we use on aircraft. Both work pretty well. Of the two I believe Flitz has protective properties.

I had good luck with happich semichrome in the past on R75 aluminium wheels.

If there are no pits, the never-dull may work. Lots of elbow grease though.

Back when I owned a semi tractor fitted with aluminum tanks and wheels, I'd use an aluminum cleaner before polishing. The cleaner would do an excellent job of removing oxidation and would leave a nice clean surface ready for polishing.

Understand, tho, that the cleaner is thinned acid. Care is recommended while using this stuff.

Nothing much will remove pits in the aluminum caused by excessive corrosion. The cleaner will remove the dark stuff in the pits, but the pits will remain.

I'd use a host of different polishes. All the stuff listed above works well, but requires either a machine polisher for pastes or elbow grease for the wadded stuff, like nevr-dull.

Some say you could put a coat of wax over the cleaned and polished aluminum when done. I never tried it. Flitz will make water bead on a polished part, but the beading effect will fade quickly.
