It very difficult to repair. We use a lot of grain-sanded stainless and it gets scratched thru the protective overlay when we are fabricating the part. For very mild scratches, I agree with the previous posters that you need to determine if the stainless has a protective clear appied. If not, and the scratches are shallow, the bar keeper's friend is the best we have found.....but it is very difficult to blend the surface....almost impossible I would predict. I suggest contacting a supplier of the appliance and getting thru to the manufacturer's people who must deal with this quite often.....you arent the first to scratch a stainless appliance. IF nothing else, move it to the garage and fill it with beer and buy her another one.
