Let the pan cool slightly after cooking, then wipe it out with a paper towel or soft cloth. For stuck-on food, add coarse salt to the pan and scrub with a paper towel or soft brush to lift residue without damaging the seasoning. Rinse briefly with warm water if needed and dry the pan immediately and thoroughly. Avoid soap, the dishwasher, and prolonged soaking, as these can strip the seasoning. After cleaning, apply a very thin layer of oil to the surface before storing.
