3M Marine Metal Repair & Polish (09019) - Boat and RV - 18 oz, Paste

It works great and it doesn't damage anything.

Expensive, but worth the money. It removes what other polishes leave behind, and in less time.

This was used to clean all stainless and aluminum on my sailboat. Had others come and try it and were thrilled with the results!

The most amazing cleaner for rusted stained stainless appliances. Use with a blu nonscratch sponge and wipe with micro fiber towel. Labor intensive but amazing results ... I do a 4 x 4 area about 15 mins a day. Getting there slowly but surely. Thiscworks! And I've tried everything

Someone in my house tried to clean my stainless steel sink with toilet bowl cleaner and it left it badly stained. I read a few of the reviews on this and thought I would give it a shot. I have a triple sink and after working on it for about an hour with a lot of elbow grease I got ride of most of the discoloration. I worked on it for another hour and the sink is pretty much back to normal. I am going to keep working on it as time permits but this is a really good product. I was worried that I was going to have to replace a very expensive sink that is mounted below quartzite countertops. I wouldn't worry about the price of the product it worked wonders. You don't have to use a lot , use it sparingly and keep changing rags. It's kind of like polishing silver or brass. It actually gives it a nice shine after you are done.
