Teach you how to easily remove tea stains

Is tea stain healthy or harmful to health? Tea contains tea polyphenols, which come into contact with air and water, which is very easy to oxidize and form tea stains, and adhere to the surface of teapots and tea cups, especially the surface of stone pots. Tea scale contains harmful substances such as arsenic, mercury, cadmium, lead, etc., which enters the human digestive system through the mouth. It is very easy to combine with proteins, fatty acids, vitamins, etc. in food to produce precipitation, hinder the absorption and digestion of nutrients by the small intestine, and can cause inflammation and even necrosis of organs such as the kidneys, liver, and stomach. Especially after ingesting tea stains in patients with ulcer disease, the condition can often worsen.

Therefore, wash tea cups and teapots frequently. If the tea set already has tea stains, you can use toothpaste, detergent, etc. to scrub it, which has a very good descaling effect.

1. Potato/egg shell descaling method

First pour about half a cup of hot water into the thermos cup, cut the potatoes into diced ones, put them in the thermos cup, then tighten the lid of the cup and shake them up and down for two minutes. Open the water cup, pour out the water and diced potatoes, and rinse it with clean water. You will find that the tea stain attached to the wall of the cup has obviously decreased. If you repeat this a few times, the tea stain can be removed. If you don’t have potatoes on hand, you can also use crushed egg shells to replace them, and the operation steps are the same.

2. Put a slice of lemon when making tea

Some foreign researchers found that brewing one bag of British black tea at a time produces more tea stains than brewing two bags at a time, and brewing five bags at a time does not produce tea stains. This is likely because the polyphenols in the tea leaves reduce the pH value of the tea soup. There is also a patented result, which is to add a small amount of citric acid to the tea bag to adjust the taste while reducing tea stains. In addition, calcium ions are the key factor in the formation of tea scale. They promote the oxidation reaction of tea polyphenols and play a cross-linking role in the polymerization process. The more water, the more tea stains the groundwater is, the hardness of groundwater is greater than surface water, and the less tea stains formed by brewing tea with pure water will be much less. Make tea in tap water to boil the water thoroughly for a few minutes. The calcium and magnesium in it will form carbonate water alkali, reducing the formation of tea scale.

3. Method of removing tea stains from citrus peels on cups

After eating oranges, everyone will discard the orange peels easily. However, here, what the editor wants to tell you is that wiping the tea cup with orange peels can remove tea stains. For teapots, etc., we can boil them with orange peel or citric acid and add water to boil them. The teapot residues can be cleaned 2-3 times.

4. Salt/toothpaste descaling method

You can prepare a clean toothbrush, soak the toothbrush bristles, dip some salt, then put the toothbrush into the cup, carefully brush the wall of the cup, and remove the dirt very well. If you don’t have salt on hand, you can also use toothpaste instead. The bottom of the cup is the most difficult part to clean when descaling. You can find a small piece of soft cloth dipped in some salt or toothpaste, wrap it on the chopsticks, then extend the chopsticks to the bottom of the thermos cup and stir it back and forth a few times.
