Glass Cup Cleaning and Maintenance

It is best to clean the glass cup immediately after each use. If it seems too troublesome, at least clean it once a day, preferably before going to bed at night, and let it dry.

When cleaning the cup, not only the rim but also the bottom and the entire cup should not be ignored, especially the bottom, which may accumulate a lot of fine particles and dirt that are not often cleaned. Professor Cai Chun specifically reminds female friends that lipstick not only contains chemical ingredients but also easily absorbs harmful substances and pathogens in the air.

When drinking water, harmful substances may be brought into the body, so the remaining lipstick on the cup rim must be cleaned thoroughly. Simply rinsing the cup with water is not enough when cleaning.

It is best to use a brush. In addition, since the main component of dishwashing detergent is a synthetic chemical, its use should be cautious, and it should be rinsed thoroughly with clean water. If you need to clean a cup with a lot of grease, dirt, or tea stains, you can squeeze toothpaste onto the brush and scrub it back and forth inside the cup.

Since toothpaste contains both a detergent and very fine abrasive, it can easily remove residue without damaging the cup.
