虽然不锈钢厨房设备不容易生锈，但盐、醋、生抽等调味品也不可能长期存放。这是因为这种调味品含有大量电解质。如果长时间放置，不锈钢就不一样了。在金属材料中，电解质会形成电流反应，引起化学变化，导致不锈钢生锈，甚至可以分离出对人体有害的元素。

Although stainless steel kitchen equipment is not easy to rust, it is not possible to store condiments such as salt, vinegar, light soy sauce and so on for a long time. This is because this condiment contains a lot of electrolytes. If it is left for a long time, stainless steel is different. In the metal material, the electrolyte will form a galvanic reaction, causing chemical changes, causing stainless steel to rust, and even the elements harmful to human health can be separated.
