Sorry

I know this sounds like a lame answer, but try Customer Service or Field Services.

 

Cleaning Cookware

Try Dawn Power Dissolver. Someone here suggested it for the glazed stoneware, too. It works well, just don't wet the area first. Let it sit for 10 to 30 minutes, then wet and wipe down. If the stains are a couple years old, it may take several tries.

You can find it near dish detergents at most supermarkets.

Thank you for contacting the Pampered Chef Test Kitchens with your product
question. To remove staining from the exterior of the Professional Cookware
a grease cutting detergent (like Dawn) and your Easy Clean Kitchen Brush
might be all you need. If this has not been successful, deep cleaning may be
necessary.

interior surfaces with a nonabrasive sponge or cloth.

tablespoons water. Apply paste to desired areas on exterior surface of
Cookware, let stand 15-20 minutes. Wipe off excess paste; rinse thoroughly
and dry.

other nylon bristle brush.
