How to Remove Rust and Protect My Stainless Steel Propeller from Rusting?

Skipper February 3, 2025 Ask The Skipper

Bruce F asked:

I just bought a boat with a ten year old outboard. The stainless propeller has rust. Here in Florida, it is exposed to humid salt air and is used in salt water.

Would your products be useful in

A: restoring the propeller, and

B: protecting it from the rust returning?

If so, would you predict more maintenance for it given its function of immersion and pressure of salt water?

To remove the rust and restore your stainless-steel propeller, use Quick Silver^® to clean and passivate the metal. Remove any loose rust. Brush on the Quick Silver^®, wait 20 minutes, keeping it wet, and rinse clean. Repeat, if necessary, until the stainless steel is clean and bright.

To protect your propeller, spray on Kwik Shine^® after each use and wipe off the haze to maintain the bright finish. Kwik Shine^® has Salt Busters, which will react with the salt on the propeller and convert it into a protective polish. You can also use Kwik Shine^® on the rest of your outboard, including the leg and cowling. The shearing and cavitation force of the propeller pushing water will render most coatings impractical as it will remove the coating. Kwik Shine^® will be required on a regular basis, but since it’s so easy to use; spray on and wipe off, you’ll find it quick and easy to use. Kwik Shine^® with Salt Busters will also remove the salt that cakes on the hub of the propeller from hot exhaust that is expelled through the hub.
