1. Vinegar
I often use a stainless steel thermos cup, and I can see that the inner wall of the thermos cup becomes black due to tea scale. Here, it can be soaked in vinegar for 30 minutes. After soaking, it can be washed with a toothbrush, so that the tea scale can be easily removed.
2. Edible salt
Soak a scrubbing tool such as gauze or paper towel, then use the soaked gauze with a small amount of edible salt, wipe the tea rust in the inner wall of the thermos with the gauze soaked in salt, or rub with a small sponge dipped in salt , the effect of removing tea scale is very significant. The main component of the salt is NACI, which contains MGCI KCI and other components. MG+ makes the hydrolysis acidic, and the acidic substance can remove the theophylline in the tea scale.
No matter it is table salt or coarse salt, it can help us remove the tea stains on the thermos cup. We can use our fingers to pick it up and brush it back and forth over the tea stains. It will take two or three minutes to find the tea stains. It has magically disappeared! And it is not easy to damage the cup body.

If there is tea scale in the teacup, pour a small amount of citric acid into the cup, then add hot water to dissolve the citric acid. After soaking for a few minutes, the tea scale can be wiped off with a cloth. Scrubbing or washing with a drink rich in citric acid can also work. Citric acid is an organic acid that can be obtained from many fruit juices (especially lemon juice) and is harmless to the human body.
9. Potato skin
Put the peeled potato skins into the thermos cup, then add boiling water to cover the lid, suffocate for 10 minutes, and then shake it up and down for a few minutes, then the tea scale in the thermos cup can be removed. Because potatoes have starch, these starches have a strong adsorption force.

If you use the peel to replace the vegetable melon cloth, dip it in the salt, and then use it to scrub the tea stains, you can also achieve unexpected good results! If the peel is not available, a little vinegar will have the same effect.
The thicker the tea scale accumulated in the thermos, the harder it will be to clean up, so daily cleaning and regular cleaning cannot be ignored. Therefore, it is recommended that after each use of the thermos cup to drink tea, even if there are no obvious tea stains visible to the naked eye, it should be carefully cleaned. If the tea scale has accumulated, you can use the above eleven methods to remove the tea scale. When cleaning, pay special attention to the mouth of the cup, because the mixture of saliva and tea remaining on the outside of the stainless steel thermos cup is more likely to breed bacteria when exposed to the air. .
