Please perform "oil leveling" before using for the first time.
The surface of the iron skillet has many micro holes. When oil gets into this hole, a thin oil film is formed on the surface of the frying pan. The point is to slowly heat the oil on medium heat or lower to evenly heat the whole. When the oil is absorbed in the frying pan, it will not burn easily and will not rust easily.
After the second time, please perform "oil return" before cooking. As soon as you start using it, the oil is not familiar to the frying pan, so the ingredients will stick to the frying pan. After that, add oil and start cooking to reduce sticking.
Please wash with hot water without using detergent.
After cooking, while the frying pan is warm, wash it with hot water using a scrubbing brush or sponge without using detergent. After cleaning, drain the water, dry it well, and then apply a thin layer of oil to the inside and outside of the frying pan with kitchen paper.
