After a new aluminum pan has been used for a period of time, the surface will darken and darken. At this time, some people wiped with stainless steel skeins and rubbed them all the way to the inside and outside. In fact, this is unscientific, not only affecting the service life of aluminum appliances, but also causing food contamination by aluminum cutlery.
On the one hand, because the wire of the stainless steel wire cleaning ball is used for a long time, it is easy to get rid of the debris. If it is eaten on a dish or bowl, it will be harmful to the body. On the other hand, aluminum pot is durable, not long rust is mainly a thin layer of alumina on its surface, this protective film can prevent and reduce the erosion of acid, alkali solution, but also increase the hardness of aluminum products.
If the aluminum oxide film is wiped off with a stainless steel cleaning ball, more aluminum will dissolve into the food when cooking. Many studies have shown that aluminum has an adverse effect on the human nervous system and can easily lead to Alzheimer's disease. On the surface, although the brush was clean, the harmful factors increased. From this point of view, aluminum pans do not use stainless steel wire balls as well, and should be cleaned with other methods.
