After less than five uses the bottom of this pan is dull gray in several areas. I only cleaned it with dawn liquid dish detergent soap, soft sponge and cloth. It has not been used to heat more than at medium high heat on electric stove. The sides of the pan looks beautiful.
A great multi-use pan for sautéing, wok frying, and searing. Staub quality cannot be beat for the price. I do wish the bottom was a tiny bit wider for searing.
