How to remove tea stains from thermos cups

Method 1: salt. Dip the toothbrush in salt to remove the tea stains.

Method 2: Coke. Pour in coke and let stand for 8 hours.

Method 3: potato skin. Put the fresh potato skin into a cup, pour in hot water and let it stand.

Method 4: baking soda. Add 3 tablespoons baking soda to boil and let stand.

Method 5: vinegar. Pour 30ml vinegar into the cup and soak it in hot water.

The above is the cleaning method to remove the tea stains in the thermos cup. I like drinking tea myself. When the cup has tea stains, I use the above method and the effect is very good.

Finally, the quality of tea must be good to be beneficial. I suggest you book tea in Jiupin official website, where pheasants can be raised under tea trees, with less pests and strict quality control. However, Jiupin produces less tea each year, so it needs to be booked in advance!
