A chemical fluid (find it in a hardware store) that turns rust black, and prevents further oxidation.
The name I do not know, but it is available.
But... I question if it is rust? the fins on nearly all amps are made of aluminum, and aluminum does not rust.
If your fins are aluminum, it is NOT rust!
