1. There are two kinds of aluminum pots: refined aluminum and cast aluminum. Materials are aluminium and aluminium alloys. Surface color can be divided into white and light yellow. White aluminum products are divided into casting and stamping. The surface of cast aluminum products has been processed by automobile polishing and mechanical polishing, and the surface is white, but the metal structure is loose, and there are certain casting defects; the surface of stamping aluminum products is washed white, polished and mechanically polished, and the surface is a natural oxide film, thin and uneven. It is easy to be scratched or worn by machinery; the yellow aluminum products are stamped products that have been anodized, and a light yellow artificial oxide film is formed on the surface. The film is thick and uniform. Under the action of strong alkali, the membrane will not be damaged. , Light yellow aluminum products are the best.

2. If you use an aluminum pot for cooking, please do not empty the pot of the pot to ignite or ignite a small amount of water to make the pot dry, otherwise it may cause water leakage at the bottom of the pot; cooked rice and soup should be put into the bowl in time, not for a long time Put it in an aluminum pan to avoid the chemical reaction between aluminum and acid and alkali substances and produce harmful substances. The material of the aluminum pan is relatively soft. When in high temperature, be careful not to hit hard objects or put it in cold water. Cool to avoid deformation.

3. When cleaning the aluminum pan, do not use acidic alkaline cleaners to avoid chemical reactions and produce harmful substances to the body. Weak alkaline ones can be used. Do not use wire brushed aluminum pans to avoid scratches. Use a sponge or a hundred pieces of clean cloth; when storing, be careful that the surface will form a protective oxide film due to contact with air, which will darken the color of the pot, but it is not necessary to wipe it off, so as not to affect the service life of the pot.
