1. It is not advisable to store salt, soy sauce, vinegar, vegetable soup, etc. for a long time, because these foods contain a lot of electrolytes. If they are stored for a long time, stainless steel will electrochemically react with these electrolytes, so that toxic metal elements are dissolved.

2. Never use a stainless steel pot to cook traditional Chinese medicine, because traditional Chinese medicine contains a variety of alkaloids, organic acids and other ingredients, especially under heating conditions, it is difficult to avoid chemical reactions with it.
