Clean it good and use the polish & see what happens.
Excellent article. Explains that even 316 SST can have this problem.
However, I would like to add this explanation of "Passivation" of SST, which is the removal of surface impurities and subsequent rebuild of the protective (invisible) oxide layer that protects the SST.

To passivate stainless steel at home without using a nitric acid bath, you need to clean the surface of all dirt, oils and oxides. The best way to do this is to use an oxalic acid based kitchen cleanser and a non-metallic green or white scrubby pad. Don't use steel wool, or any metal pad, even stainless steel, because this will actually promote rust. Scour the surface thoroughly and then rinse and dry it with a towel. Once you have cleaned it to bare metal it will re-passivate itself.
The cleaning with the acid based cleaners may do the trick, and the rust might not come back.
However, if the iron contamination is coming from an environmental source (high iron content in your wash water, or iron dust from nearby manufacturing facility or the dock roof structure), then the problem will continue.
Salt water is not the problem. It only makes the problem show up quicker.
