Hi, thanks for using JustAnswer.com. There is a product that I use on stainless steel surfaces with great success. It comes as a kit for refinishing marred stainless. It is available at C E Sundberg Co. at 1-800-735-3796. I can't remember the name of it, but it is the only kit they sell. It works very well, and I have used it alot to refinish scratched surfaces, including stainless sinks. I would recommend trying that.
