1, baking soda, tea scale is not easy to clean up after a long time. You can soak it in heated rice vinegar or baking soda for a day and a night, and then brush it with a toothbrush, which is easy to clean. It should be noted that if you use a teapot, you don't need to clean it like this. The teapot itself has pores, and the minerals in the tea scale can be absorbed by these pores, which can not only maintain the teapot, but also prevent harmful substances from "running" into the tea and being absorbed by the human body.

2, toothpaste, soaked for a long time, many tea sets are brown, can not be washed off with water. At this time, a small amount of toothpaste can be squeezed on the tea set, and the toothpaste can be evenly coated on the surface of the tea set by hand or cotton swab. Wash these tea sets with clean water in about a minute, so that the tea stains on the tea sets can be easily cleaned. Cleaning with toothpaste is not only convenient, but also convenient and simple, without damaging the tea set or hurting hands. People who love tea can try it.

3, vinegar, pour some vinegar in the kettle, gently brush with a soft brush, so that the scale and vinegar fully contact, if there is stubbornness, you can pour some hot water to continue brushing, and then rinse with water after the scale completely disappears. The main component of scale is calcium carbonate, which is insoluble in water, so it will form on the bottle wall. There is acetic acid in vinegar, which can react with calcium carbonate to form water-soluble salt, so it can be washed off.

4, potato skin, potato skin to remove tea stains, the easiest way to remove is: help with potato skin. Put the potato skin into the teacup, then add boiling water, cover it, keep it stuffy for 5 ~ 10 minutes, and shake it up and down a few times to remove the tea stains. There is starch in potatoes, which has strong breath absorption ability and can easily remove dirt from cups.

5, lemon peel, tea stains and water stains on porcelain, juice squeezed from lemon peel, and a small bowl of warm water are poured into the vessel and soaked for 4 to 5 hours, which can be removed. If it is a coffee pot, you can wrap the lemon slices in cloth and put them in the upper part of the coffee pot and fill them with water. Boil the lemon with the method of making coffee and let it drip into the pot below until yellow water drops appear in the coffee pot.

6, egg shell, just crush the eggshell, put it into a dirty cup or bottle to be cleaned, then drop a few drops of vinegar, slowly shake it, and then clean it with a brush, you can clean the parts that are not easy to clean at ordinary times. In addition to tea dirt, eggshells can also effectively remove dirt. It is easy to scale in a thermos bottle with hot water for a long time, and the scale at the bottom of the thermos bottle is not easy to remove because of the narrow bottle mouth. You might as well put some broken eggshells in the water bottle, add some water and a proper amount of detergent, cover the bottle cap and shake it up and down, and finally rinse it with clear water several times, which can effectively remove the scale in the thermos bottle.

7. Salt: Apply edible salt to the inside of the cup, especially where there is tea dirt, then scrub the cup with a toothbrush or hands, and finally rinse it with water.

I think it's best to clean it immediately after each use.
