How to remove tea stains from ceramic cups?

May 21, 2023

Everyone knows that ceramic cups are very popular among people. Ceramic cups are harmless to the human body, but drinking tea with ceramic cups can also leave tea stains. So how do you remove them? The tea stains on the inner walls of tea sets contain various metal substances that are brought into the body during tea drinking, and combine with nutrients such as proteins, fats, and vitamins in food to form insoluble precipitates that hinder nutrient absorption, especially arsenic and cadmium, which can cause cancer and affect physical health. Therefore, those who have a habit of drinking tea should regularly clean the tea stains on the inner walls of tea sets.
