1. Wash the blackened wok with cold water first, then put it on the stove and burn it on the fire until it gets hot (it is advisable to put it on the wok by hand).

2. Then pour a bowl of vinegar into the pot. When the "squeak" sound comes out, use the kitchen broom to wash around the pot twice, then throw away the vinegar and wash the pot with cold water. The dishes cooked in this way are delicious and will never turn black again.
