1, fat cleaning method. After the wok is heated, add the fat with skin, turn to low heat, spread the fat on the wok wall with chopsticks until the fat turns black, take out the meat, rinse the wok with warm water, and repeat several times. Note, however, that you don't need to clean the oil for the last time. Before cooking the next day, you can wash the pot with clean water.

2. Salt cleaning method. After the wok is heated, put a tablespoon of salt (both edible salt and coarse salt) into the wok, turn off the heat and stir fry constantly. When cooking, keep turning the wok to ensure that the salt can touch all parts of the inner wall of the wok. When the salt is browned, turn off the fire, pour out the salt and clean the wok with warm water.

3. Ginger cleaning method. After the wok is heated, put the ginger slices into the wok, turn the heat down, clamp the ginger slices with chopsticks, and evenly smear all parts of the inner wall of the wok for 3-5 minutes.
