How to remove tea stains

Scientific research shows that drinking water contains minerals and trace amounts of harmful heavy metal ions, such as cadmium and arsenic. When water is heated, as the water temperature rises, the solubility of calcium and magnesium ions decreases, and the concentration of insoluble salts continues to increase. When the water is concentrated to a certain degree, precipitation occurs. These precipitates can enter the teacup along with the water used to brew tea, and tea that has not been finished or has been left for a long time will be exposed to the air. Let's learn how to remove tea stains.

1. Pour white vinegar or balsamic vinegar into the teacup container, let it sit for 5 minutes, then gently brush it with a special brush for washing teacups, and the original solid tea stains will soften and fall off.

2. Put an appropriate amount of baking soda into a teacup and add water to melt it. After standing for a while, the baking soda water can quickly decompose the tea scale. Even if some tea scale is hanging in the cup, it can be easily scraped off with a brush. The cup will be clean and bright after cleaning.

3. Add some water into the cup, squeeze toothpaste on the brush head, put it into the cup to clean, the toothpaste foam can also quickly remove the tea stains in the cup.

4. Put a slice of lemon in a cup, add some hot water, wait for a few minutes, you will find that the tea stains in the cup are melted by the acidic lemon water, and the hot water speeds up the effect of the acidic liquid.

The above provides a series of answers to the question of how to remove tea stains. Tea contains tea polyphenols which have anti-cancer effects, tea polysaccharides which can lower blood sugar, caffeine which excites the central nervous system, as well as a variety of amino acids, vitamins and other nutrients. How much of these nutrients can be precipitated has a lot to do with the number of times it is brewed.
