You want to assure you use a slightly abrasive scrubber; such as the black nylon scrubber which comes in our Costco packs. Alternatively, you can buy them directly from us at {1.800.565.9972}. Get the abrasive scrubber seeping wet with hot water, apply that wet scrubber directly to the container of Universal Scrub (Formerly Mothers Choice), lather between your thumb and fingers and scrub the pot in a circular motion assuring to cover the entirety of the burnt surface. Leave the pot for a few hours so the solution can set in. Come back to it and scrub it off with the abrasive scrubber, seeping wet with hot water. Repeat if necessary.
