If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

How to remove oxidation from aluminum

I know its been talked about before, but it oxidized motor covers or forks. What about rims? Its really hard to get around the spokes and keep the direction of abrasive travel the same. I have 4 wheels to do!
 
Aluminum oxide is so hard it is used as sandpaper abrasive. Chemicals wont hardly touch it, the base metal is way softer. Basically you have to get medieval with it. Wire brush it, then polish. Bead blasting, or sand blasting works too.
 
I have a 3 inch yellow sewn pad that has a 1/4 inch hole in the center. This fits on an arbor that goes in my air tool and that used with aluminum polish does the trick quickly.

And Mothers makes what they call a power cone and a power ball..both go in the drill and are also very good tools for polishing rims.
 
silicon carbide sandpaper
easy to do
use the least abrasive paper that does the job or you will make a mess of things
 
Power balls and cones arent cheap..if you go that route use an electric drill. battery ones wont keep up with the size of the task...spend more time waiting on battery to charge than actually working.
 
Thanks gentlemen. I didnt realize the stuff was so tough. I had to use a dremmel on the spokes,they were nasty but after my accident I had lots of time on my hands and needed to do something besides eat and watch netflix.
