Magnet identification

You can distinguish the quality of stainless steel cup with an ordinary magnet. If the magnetism of the stainless steel product is very strong, it proves that it is almost pure iron. Since it is iron and the appearance is bright, it means that it is an electroplated product, not a real stainless steel. Real stainless steel cups also contain iron and are a little bit magnetic, but they are relatively weak.

Lemon identification method

Prepare a lemon and pour the lemon juice on the surface of the stainless steel product. After ten minutes, dry the lemon juice. If there are obvious marks on the surface of the stainless steel cup, it means that its quality is not good and it is easy to be corroded.
