I have not used the "scotchbrite" type pads so can't speak for that approach.
If the scratching is very light (shallow) you should be able to get away with little or no hard abrasives. I have been using cotton & felt buffing wheels on a bench grinder for many yrs w/ excellent results - different compounds are used for different materials and cutting vs polishing. Here are a couple of links that cover the approach in more detail - and describe the process better than I can...
Polishing Stainless Steel and Aluminum
AN INTRODUCTION TO BUFFING & POLISHING
This site has a link to "download the complete booklet" - it shows pics of various tools, wheels, etc that the short article doesn't include.
Harbor Freight has some inexpensive buff sets w/ 1/4' shaft for use in drill, die grinder, RotoZip or Dremel type tools - higher RPM is definitely better and higher HP motors better but for small areas you can probably get away w/ drill or one of the lighter weight alternative tools.
I forget which color buffing compound is recommended for SS but you can find it online if not given in the above links... again one is better for cutting and another for final high luster polish. Last time a bought some polishing compound it was a large flea market that had some tools vendors but I'm sure you can find it online or possibly at a Sears which is where my original set of 4 compounds came from.
Good Luck - again... let us know how it works out
