Do not scour a seasoned wok. Just wash it in plain water without detergent. Dry it thoroughly, preferably by placing it over a low heat for a few minutes before putting it away. This should prevent the wok from rusting; but if it does rust, scrub it off with kitchen cleanser and repeat the seasoning process. If you wish to store it for a long while or if you live in a damp or humid climate, rub the inside of the wok with one dessertspoon of cooking oil for added protection before storing.
