1. Put the wok under the faucet, wipe every corner with a soft cloth, and wash off the impurities and dust in the casting process of the wok. Be careful not to use any washing products.

2. After electrifying, heat the pot to silver blue, add oil, and then wipe the oil evenly with a napkin. Every place is covered with oil film, and there is no oil drop in the whole process, so it should be applied evenly and repeatedly. After a period of time, the oil will become sticky, yellow and adsorbed on the bottom of the pot. At this time, you can put more oil, rub it quickly and repeatedly, and smoke will come out.

3. Turn off the fire, let the pan cool and rinse it with cold water. Turn on the small fire again and prepare for the second boiling. Rotate all parts of the pot, at least add four sides to the bottom, and bake over low heat. Continue to rotate and apply fat. This process will continue for 3-5 minutes.

4. Rinse clean, continue to dry with low fire, then coat with a layer of soybean oil or peanut oil, and leave it overnight to complete the maintenance.
