How often is it better to change the pot?

The wok for cooking at home is generally recommended to be replaced once a year or so. If it is a pan, after a period of use, the bottom of the pan will be deformed due to long-term high temperature. The uneven bottom of the pot will affect the appearance and cooking and needs to be replaced. A wok with good quality can be used until it is damaged and unusable.

Extended data:

Ordinary iron pots rust easily. After the human body absorbs too much rust, it will cause damage to the liver. When using iron pots, you should follow some principles to be healthy.

Principle 1: After each meal, the inner wall of the pot must be washed and dried to avoid the rust of the pot and the generation of iron oxide harmful to human health.

Principle 2: Some people are used to washing the cooked wok under the tap, and smoke is everywhere in an instant. At this time, the fine suspended particles lurking in the air increase sharply, which is not conducive to health and should be avoided.

Principle 3: Don't use an iron pot to hold vegetables overnight, because iron will dissolve out of the iron pot under acidic conditions and destroy vitamin C in vegetables.

Principle 4: Use detergent as little as possible when washing pots. If the pot is slightly rusted, it can be cleaned with vinegar.

Principle 5: Do not use iron pans with serious rust, black slag and black skin.
