A rainbow sheen inside a pan does not automatically mean it must be discarded. All-Clad and Made In describe ordinary heat tint as largely cosmetic. These steps apply to uncoated stainless steel, not nonstick, enamel or specialty finishes. Follow the specific manufacturer guide and distinguish structural damage from color alone.

1. Identify the surface and damage. Confirm from the manual that the cooking surface is uncoated stainless steel. If the base is warped or the pan has deep cracks or serious corrosion, consult the maker rather than treating it as a color stain.
2. Turn off the heat and let the pan cool fully. Never shock a very hot pan with cold water. Let it cool naturally on a heat-safe surface to help prevent warping.
3. Wash away everyday residue first. Use lukewarm water, mild dish soap and a soft sponge to remove grease and food. Avoid steel wool, rough abrasives and oven cleaners.
4. Apply a little white vinegar to the rainbow tint. Gently wipe the discolored area with a soft cloth or sponge dampened with vinegar. Never mix vinegar with other cleaners, especially chlorine bleach.
5. Rinse thoroughly and dry at once. Remove all vinegar and soap residue, then towel-dry with a soft cloth to reduce new water spots.
6. Prevent excessive heat next time. Do not leave an empty pan over high heat; preheat gradually over low to medium heat. Color alone usually does not impair a flat, undamaged stainless pan. Your particular product manual takes priority.
