<VV> On cleaning...

[Danny Davis]

Gasoline is a great parts cleaner along with wire brushes.
After clean and dry use phosphoric acid to remove the rust.
I paint them "cast iron"  color when done and they look great  and you no
longer have rust to worry about.
Put the fan on a bearing hub while you are painting...
