You must take care when cleaning your cast iron wok. You can't use a heavy scourer lest it take off layers of hard-won seasoning, and you certainly can't stick it in the dishwasher. If it doesn't have any foodstuff stuck to it, simply wipe it with a clean cloth and store it. Otherwise, wash it by hand with a soft sponge or dishcloth, and dry it carefully.Some people advise never to use dish soap on a cast iron wok, but we haven't found this to be problematic.
