Thank you for your question and I understand your concern. Deep scratches can not be removed but very minor and superficial scratches can some times be polished out.
Generally speaking, scratches can not be removed from the stainless steel unless they are superficial scratches. Superficial scratches could possibly be polished out using a fine abrasive cleaner like Bar Keepers Friend.
Since I do not know exactly what type finish and grade of stainless steel is used, try a small inconspicuous area with Bar Keepers Friend first before trying on a visible area. Be sure to rub along with the grain and not against.
Here is a product that does this: Stainless steel scratch treatments.
