How to remove tea stains from thermos cups

1, if you have decontamination powder at home, you can use it directly, which is very decontamination. Mom often uses this to decontaminate. But be sure to clean it after use.

2. If there is no decontamination powder, you can wipe the cup with a wet rag and salt powder, and the same effect is obvious.

3, you can use acid to neutralize the alkali in tea stains: dilute white vinegar with water, pour it into a teacup and soak it for a while. The longer the time, the more obvious the effect. Then scrub with a rag to easily remove tea stains.

4. The healthiest method: fruit descaling method. Find some acidic fruits, such as oranges and lemons, and juice them to soak tea stains. Don't throw away orange peel and lemon peel. It is healthiest to wipe stubborn dirt directly with water peel after soaking. Finally, rinse with clean water.
