Stainless steel appliances seem to be stained with fingerprints constantly. But to give them a good, clean shine, all you need is a microfiber cloth (or just a soft cloth) and some rubbing alcohol! If you really want to get your stainless steel super clean - once a month use a few drops of olive oil to mask scratches, erase water spots and repel smudges. When done with either treatment, buff to shine.
