How badly scratched is it? Youmight be able to just polish them out with a good metal polish and a cloth. If not, you can get buffing wheels that mount to a drill at most hardware stores, Menard's, Lowes's, and Sears have them for sure. Some of the kits will come with a few small bars of posish for different applications. You'll want to use the white rouge on stainless. Then go over it by hand to take out any swirl marks and such.
