The first is stainless steel. Stainless steel tableware is not easy to rust, has good corrosion resistance, and is not easy to damage. However, stainless steel tableware contains many trace elements, such as lead and manganese. After long-term use, these elements may permeate out and endanger people’s health. When stainless steel cutlery is scratched or the coating falls off, it is recommended to replace it in time according to your own conditions, generally every three years.
Second, wooden tableware. Wooden tableware is a very common tableware material. The cutting boards, chopsticks and rolling pins we use are all made of wood. The service life of wooden tableware is shorter than that of stainless steel tableware. Generally speaking, it needs to be replaced within three to six months.
If you find black spots on the wooden tableware, it means that it is moldy and should be replaced in time, because if the wooden tableware is moldy, it is easy to breed aflatoxin, which is harmful to human health. It should be noted that the black spots formed by mildew cannot be removed by heating and cleaning, so they can only be replaced.
Third, ceramic tableware. Ceramic tableware is relatively healthy. It does not contain various trace elements like stainless steel tableware, nor is it as easy to breed mold as wooden tableware. As long as there is no crack and does not affect the use, it can be used all the time.
