I will sometimes use Cameo or Barkeepers Friend, but any non abrasive cleaner should work (not Bon Ami). This gets off the water stains that seem to appear in our area. Our pans are 20 years old and still look new. If it is really bad, then the boiling water trick will take care of it.Any tips for keeping stainless steel clean? I have always been hesitant to buy it because it seems hard to clean.
