Scanpan can be washed in the dishwasher. However, I recommend hand washing high-quality cookware to prolong its life. You can usually remove most stubborn stains with warm water, mild detergent, and a sponge, but if they persist, rub a paste of water and Bar Keepers Friend or baking soda on the pan. Rinse with water after letting it sit for thirty minutes and scrubbing with a sponge.
