Of all the materials, glass is the healthiest. This glass contains no organic chemicals during firing. When people drink water or other drinks from glasses, they don't have to worry about chemicals being drunk into their stomach. Moreover, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the glass wall. Therefore, drinking water in a glass is the healthiest and safest. So how does it need to clean the bottom of the glass?
1. If you use the glass every time, you can wash it immediately. If it's too much trouble, you should at least clean it every day. You can wash it before going to bed at night and then air dry it. When cleaning the cup, not only the mouth, but also the bottom and wall of the cup can not be ignored, especially the bottom. If it is not cleaned frequently, a large number of bacteria and impurities may precipitate.
2. Remind female friends that lipstick not only contains chemical components, but also easily absorbs harmful substances and pathogens in the air. Drinking water will bring harmful substances into the body, so the lipstick left in the cup must be cleaned. Washing with water alone is not enough. Clean the cup with a brush. In addition, as the important component of detergent is chemical synthetic agent, be careful when using it and pay attention to washing with water.
3. Clean the cup with a large amount of oil, dirt or tea stains, apply toothpaste on the brush and brush back and forth inside the cup. Because toothpaste contains detergent and fine friction agent, it is easy to wipe off residual substances without damaging the cup.
