Following Maine's advice I used Spotless Stainless on almost all of my boats SS rigging. Blocks, shackles, tangs, nuts and bolts, etc. It worked best when I could coat an item and put it in a gallon baggy to keep it damp. Then just hose it off.
When it came to railing and stanchions, it was harder to put on and keep it moist for it to work. Then I tried Flitz metal polish on the railings and stanchions. I was very happy with those results as well. Giving the boat a fresh water rinse after a sail really helps to keep the slight surface rust from reappearing.
Now I keep both Spotless Stainless and Flitz metal polish with my cleaning supplies.
