For many years, All Clad put a note in each box of their cookware that said to use Barkeeper's Friend to clean it. This stuff is strong enough to get cooked-on oil off but gentle enough to maintain the mirror finish of their shiny stainless steel cookware. They bill it as a 'non-abrasive abrasive' - we like that description just fine. You don't need to use much - just a sprinkling on a damp sponge. We use it at home on our glass shower doors and stainless bath fixtures. It's a 12 oz. can.
