Removing rust spots from stainless steel

I just bought a sailboat which has been in salt water all of its life. Some of the external stainless fittings have small pits of surface rust
showing in places.
What would be the best method for completely removing the rust, and treating the stainless to try to keep the rust from coming back?

If the fittings truely are stainless in the 300 series family, they need to be cleaned and passivated. Cleaning needs to be done without using carbon steel materials to avoid surface contamination. Mil spec level passivating is done with hot 30% nitric acid (!!!), you can do a light duty passivation with more readily available acids. (not sure which I'd reccomend)

I have been using their stuff for years. Very safe, very fast, great results, and easy to use.
