What is the “rainbow” appearance/ discoloration on my stainless steel cookware and how do I remove it?
A. When stainless steel is exposed to high heat or washed with water that has a high mineral content, your stainless cookware can discolor. If this occurs, clean your cookware with a non-abrasive stainless steel cleaner. This color will not affect the performance of your cookware, just the appearance.
