Although the glass is transparent and beautiful, it is not easy to preserve, and must be placed carefully. In fact, among all the cups made of materials, glass is the healthiest. Because the glass does not contain organic chemicals, when people drink water or other drinks with the glass, they do not have to worry about harmful chemicals being drunk into their stomachs, and the glass surface is smooth and easy to clean, so it is the most healthy and safe for people to drink water with the glass.
It is best to wash glass cups immediately after each use. If you feel too troublesome, you should also wash them at least once a day. You can wash them before going to bed at night, and then dry them in the air. When cleaning the cup, not only the mouth, but also the bottom and wall of the cup should not be ignored. Especially the bottom of the cup, which is not usually cleaned, may deposit a lot of bacteria and impurities. Professor Cai Chun specially reminded female friends that lipstick not only contains chemical components, but also easily absorbs harmful substances and pathogens in the air. When drinking water, harmful substances will be brought into the body. Therefore, lipstick residue at the mouth of the cup must be cleaned. It is not enough to simply wash the cup with water. It is better to use a brush. In addition, since the important component of detergent is chemical synthetic agent, it should be used carefully, and it should be washed with clean water. If you want to clean a cup stained with a lot of grease, dirt or tea dirt, you can squeeze toothpaste on the brush and brush back and forth in the cup. As there are both detergents and very fine friction agents in the toothpaste, it is easy to wipe away the residual substances without damaging the cup body.
