Dear husband routinely burns oatmeal in both our Revere Ware and Kirkland All Clad pans. I will let the pan cool then pour in white 5% Vinegar or Apple Cider Vinegar in it, bring it to a hard boil, turn off the hit and put the lid on it, then let it cool down, I then use a fork to scrape the burnt food out of it. Works like a charm.
