Rainbow stains on stainless steel pans

Rainbow color on uncoated stainless can follow high heat. All-Clad recommends white vinegar and a soft cloth for this discoloration, followed by rinsing and drying.

Cleaning steps

  1. Let the uncoated stainless pan cool.
  2. Apply white vinegar with a soft cloth, following All-Clad’s instructions.
  3. Rinse and dry.

What to avoid

Follow the surface-specific instruction

Let the pan cool. Distinguish a colored film from stuck food or mineral deposits, then use the maker’s method for that mark. Cleaning a stain does not repair a distorted base or damaged coating.
