Water and tea form tea scale if with drinking tea into the digestive system, it is easy to combine with the proteins, fatty acids and vitamins in food to form a variety of harmful substances, which will not only hinder the body’s absorption and digestion, but also damage many organs, such as neurological, urinary system, gastrointestinal tract, hematopoietic system and other diseases, and can even lead to premature aging.
Tea stains can be detected in the lead, mercury, although very little, but not wash tea stains over the years, easy to breed mold. It is always beneficial and harmless to wash the cup frequently. However, general and common cleaning methods are not effective in removing tea stains.
Here, I will talk about how to remove tea stains from cups by dividing it into two categories: manual cleaning and ultrasonic cleaning.
Manual cleaning methods of tea scale on the cup
1, salt cleaning tea scale method, cleaning tea scale with salt is the use of hand or sponge dipped in salt, evenly coated to cover the tea stains. Rub until the tea stain is wiped off, then rinse with water.
2、Add white vinegar to egg shells to clean tea scale. We can break the eggshell, grind it into powder, add white vinegar and brush it with a brush, or you can add white vinegar directly to clean it.
3、Toothpaste cleaning tea stains method. Squeeze out the toothpaste and apply it evenly on the inner surface of the tea cup. Use steel wool or rag to repeatedly apply and clean the surface of the tea stain. When the toothpaste turns yellow, it means that the tea stain has been washed off, and then just wash it off with water.

Ultrasonic cleaning machine its cleaning tea stains principle: ultrasonic cleaning machine generator emits a high-frequency oscillation signal, converted into high-frequency mechanical oscillation through the transducer, spread to the cleaning tank medium, ultrasonic radiation in the cleaning fluid, so that the liquid vibration and produce tens of thousands of tiny bubbles, these bubbles under the action of ultrasonic waves continue to expand and close, this is called the cavitation effect, the tiny bubble closure can produce more than 1000 atmospheric pressure instant high pressure blast, continuous shock wave, like a series of small firecrackers, constantly impact the surface of ceramic teaware, so that the surface of ceramic teaware and crevices in the dirt quickly peeled off, so as to achieve the purpose of cleaning.
