Wok preparation and caring
Make sure to seriously wash the wok before initial use. Scrub it with hot soapy water and dry thoroughly. 

After drying, place the wok over the stove on high heat until it starts to smoke. Rotate the pan so that all parts of the inside are exposed to high heat. Then rub the wok with oil on a paper towel. 

After this, try not to scrub the wok. A rinse and rub down are usually all that is needed to clean it up. Always rub the wok with a little bit of vegetable oil after washing/drying. That will help to prevent rust.

And the most important factor of seasoning a wok is to use it. It's definiteily my most used kitchen item, and it's just getting better and better with each use!
