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.
1. Wipe the ceramic cup with a bath towel dipped in white vinegar and rinse with water, usually without leaving any odor.
2. Use a toothbrush dipped in toothpaste to brush the ceramic cup, slowly brush with a toothbrush, rinse with water, and be careful not to use excessive force. If the cup has cracks, be careful to clean it.
3. Place the egg skin into a cup, add water, cover the rim with your hand, and gently shake.
4. Put a little salt in the cup and soak the ceramic cup in water. If there are many stains, you can directly sprinkle salt on the cup wall, wipe off the tea stains with your hands, and then rinse with clean water.
5.If the tea stains on the ceramic cup have not been treated for a long time, you can consider purchasing safe dilute hydrochloric acid and soaking it in the cup for a few minutes.
