Oxidation - test-drb@ccmp.vtda.org

gingerly. Fine steel wool (uh, #000 or #0000) is available at craft stores. Scotch Bright
pads also. Use a lubricant, light oil (even cooking/vegatable oils), or paint
thinner/mineral spirits, even water (like when you wet sand a paint job). Be careful of
the refuse that will result. I'm not familiar w/this equipment, might need to do some
dismantling. Rinse the surfaces thoroughly. I'm no expert..

 aluminum but the white material looks similar to aluminum oxidation. 
I'll bet that stuff's galvanized (zinc-plated).
