How to Clean a Stainless Boat Propeller

Dip the "scrubbing" side of a scrubber sponge into rubbing compound. Scrub all the surfaces of the stainless steel propeller with the scrubber sponge to remove rust. Scrub with the rubbing compound until the surface of the propeller is clean.

Mix 1 cup of Epsom salts with 1 gallon of water. Dip a clean cloth into the mix and use it to wash the stainless propeller that's turned white from calcium or lime in the water. An alternative to Epsom salts is a commercial lime and calcium removal chemical, available at most discount retailers.

Apply chrome bumper polish to the clean propeller with a clean cloth, using a circular motion to ensure complete coverage. Allow the polish to dry to a haze, then wipe it away with a second, clean cloth. This helps protect the propeller's surface and prevent or minimize a reoccurring problem.
