I need a little help please. I purchased a set of tower speakers and the cans have some white oxidation spots on them. I have wet sanded them with 600 paper and followed up with Eagle1 Mag & Aluminum polish. That removed most of the spots but I have a few tough ones I'm still working on. Any suggestions??:o

Ric, are they raw aluminum or painted? If raw aluminum, just sand the spots good with 2000 micro fine wet/dry, polish, apply a coat of wax then some Rain-X. Could be, any brackish water and some salt air in the Jax area may accelerate the tarnishing and make it hard to remove.
I finally bought a good grinder, grinder stand and mounted a buffing wheel on one end that make polishing a breeze. S/S, Bronze, Aluminum, Plexiglass and Lexan is now no problem. Smaller stuff I once had someone else do I do myself.

Aluminum foil? I use it on chrome to good effect, which if you try it on a test area to make sure it won't scratch your aluminum might be a decent solution for you.

They are the factory aluminum. You are correct they were on an 04 boat sitting on a lift in the St. Johns. So they were exposed to brackish water. I'll keep sanding, worked on them for about 2 hours last night.
Thanks, Harold!
