2. Salt, whether it is salt or coarse salt, can help remove tea stains from cups. After touching with your fingers, brush back and forth over the tea stains. In less than two or three minutes, you will find that the tea stains have disappeared! And that cup body is not easy to be hurt.
3, citrus peel, sometimes you will encounter old dirt, don't worry! At this time, you might as well look for the lemon left in the kitchen, or the peel you want to throw away after eating oranges! For coffee cups, use lemon slices or a little vinegar to wipe the rim of the cup, while for coffee pots, slice the lemon, wrap it in cloth and put it on the top of the coffee pot, and add water to the top. Boil the lemon with coffee and let it drip into the pot below. Yellow water drops flowed from the coffee pot, which is the evidence that citric acid removes coffee stains. Generally speaking, it is enough to clean the coffee pot twice or so.
4. Add salt to the peel. If you use peel instead of cabbage cloth and use it to scrub tea stains after dipping in salt, you can also achieve unexpected good results! If there is no peel, a little vinegar will have the same effect.
5, kitchen bleach, first dilute the kitchen bleach in a large basin, then put the cup in it for one night, and wash it with water the next day.
