After cleaning your sink, it will be shiny and bright, and polishing will bring it back to that. Using a small piece of cloth that is dipped in a little olive oil or baby oil, buff the sink against its grain. This treatment increases shine and provides a protective coating that resists water and fingerprints. Remember to apply a small amount to prevent an oily sensation. Regular polishing does not only enhance the appearance, but also keeps your stainless steel sink in good condition and shiny with minimal effort.
