2. Enamel cups: Experts also advocate the use of enamel cups. Enamel is resistant to high temperature and corrosion, and contains stable metallic substances, but it may dissolve in acidic environment. Therefore, it is best not to use enamel cups to hold acidic drinks for a long time. In addition, the surface of enamel cup is easy to be damaged after bumping, and harmful substances are precipitated, so it should be eliminated decisively.

In addition, the cup is affected by static electricity such as computers and cabinets, which will absorb more dust, bacteria and germs and affect health for a long time. To this end, experts suggest that it is best to provide a lid for the cup and keep it away from computers and other electrical appliances. Usually, we should keep the indoor air circulating, open the window for ventilation, and let the dust go with the wind.

4. Stainless steel cups: Stainless steel cups are alloy products. Improper use will release the heavy metal substances contained in it, which is harmful to health. Therefore, in daily use, do not use stainless steel cups to hold acidic drinks, such as juice, coffee, carbonated drinks and so on.
