Stainless Steel Cleaner
I've had fantastic results using a product made by Wichard, the French stainless steel hardware company. It's a bit hard to find... it's called Wichinox. Found out about it in Don Casey's This Old Boat book.
All you do is put it on with a rag (I also use a toothbrush for the hard to get parts) and let it sit for about a half hour. No rubbing, no scrubbing - just wipe it on. Then wash the boat with soap and water, like usual, and it will come off with the soap and water. Then wipe off any water spots with a towel as usual. The stainless will - honest to Gawd - look like new.
The best thing about it is that it (according to Casey, and the manufacturer) "re-passivates" the stainless steel, making it less prone to rust in the future. It has (I think) some kind of acid in it, which restores the metal to it's original rust-resistant quality.
I think you'll be pleased with the results, and it beats the hell out of scrubbing with chrome polish.
I know you can get it from the new SailNet site, and I was shopping around for it on Froogle and got some better prices - around $14 a tube.
Good luck.
