I'm in the process of rejuvenating an IBM model 29 keypunch, and a
couple of areas have some sort of oxidation on them. The card drum is the
worst:

The steel parts are fine, but the rest has a white material over most
of it. I'm not sure what sort of metal it is, looks a bit dark for
aluminum but the white material looks similar to aluminum oxidation.
What's a good approach to cleaning it up?
