1. Rinse the new iron pot you bought with clean water and wipe it dry with a clean cloth, but be careful not to use detergent to wash the pot. After washing, heat the pot to ensure that the moisture on the surface of the pot is removed in preparation for subsequent cooking.

2. Heat the iron pot over medium-low heat, and wipe the pot repeatedly with fat pork. You can wipe it from top to bottom, from the middle to the surroundings. As you keep wiping, the overflowing liquid in the pot will melt. As more and more black lard becomes available, the fat will turn black and smaller, and then you can turn off the heat.

3. Let the iron pot cool down naturally and then wash it with clean water. Do not use detergent. Then the parts where the lard turns black and mushy can be cut off, and the pot can be dried on the stove after washing.

4. Continue to follow the second step to open the pot. The entire lard cleaning process must be performed three times or more.

5. After rubbing lard on the iron pot three to four times, clean it and dry it over the stove fire.

6. Use kitchen paper dipped in cooking oil and smear it on the inner wall of the iron pot, and the entire iron pot is finished.
