Never use soap and don’t wash a seasoned wok in the dishwasher—the detergents will damage the seasoning. Simply clean it with hot water and a soft sponge. If you have any hard-to-release food, fill the wok with an inch or so of water and gently heat on the stove to loosen the food. Rinse the pan thoroughly. Air-drying a wok may cause it to rust. Instead, place over low heat until all the water has evaporated, 1 to 3 minutes. Or wipe completely dry with a towel before storing.
