Product can become warped or 'out of round' from extreme temperature changes. Washing a hot pan in cold water can cause it to warp.
The bigger the difference in temperature between the liquid and the pan, the more chance for the cookware to warp. For instance, if you deglaze a pan with tepid or room-temperature wine, that’s fine. But if the liquids are cold or chilled, then they have a higher probability of warping the pan.
When it comes to washing, we suggest letting pans cool briefly and then using tepid water to wash them. You should always avoid complete submersion until the pan has cooled.
