Treatment methods to prevent new iron pan from rusting;
Method 1: heat the new wok before use, then pour in some cooking oil, wipe it evenly, and leave it for one day and then clean it before use. The function is to remove the odor in the new pot and prevent the iron pot from rusting.
Method 2: Buy a piece of fat pork with skin, put the pot on the stove and heat it on low heat. The wok is hot. Put the prepared fat into the wok and keep the fire low. Hold the fat with skin with chopsticks and rub it back and forth in the pot. Make sure that the skin rubs against every part of the inner wall of the iron pot. The whole process takes about 10 minutes, and finally the pot can be washed. This process is called "moistening the pot". Lard is rich in oil, which allows oil to penetrate into the pot and is not easy to rust in the future.
