Many of us soak our cookware in water for several hours or overnight to loosen baked-on food and make cleanup easier. While this practice works, it also can have the unintended consequence of warping the pan over time, making it defective and difficult to use. To protect your cookware investment, allow your pans to cool to room temperature, then immerse in water for several minutes. That should be enough soaking time to make cleanup easier without risking any damage to your pans.
