Why should tea stains be removed in time for drinking tea

Although drinking tea is good for body and mind, if you do not pay attention to details and habits, it may be counterproductive, and health care will not hurt your body.

There is a saying in our country: "Drinking tea without washing the cup, the king will urge his life".

As we all know, tea utensils such as teacups and teapots are prone to accumulate tea stains, but many people disagree with this and don't like to clean up. Most of the tea is simply washed away after drinking.

Many people think that more tea stains can increase the fragrance of tea. Tea has thicker tea stains to achieve the effect of "no tea three-point fragrance".

Not knowing this habitual understanding, it is likely to lay serious hidden dangers for yourself.

Tea scale is caused by the oxidation reaction of tea polyphenols in tea leaves with metal substances in tea rust in the air.

Among them, cadmium, lead, iron, arsenic, mercury and other metals and nitrite and other harmful substances will adhere to the smooth surface of the tea cup.

The tea scale enters the body along with drinking tea, and combines with nutrients such as protein, fat and vitamins in the food to form an insoluble precipitate, which hinders the absorption of nutrients.

At the same time, the entry of these oxides into the body can also cause nerve and digestive system lesions and dysfunction, and even cause premature aging.

You can't think that if there is not much tea scale, you don't need to clean it. You must clean the tea set every time you drink tea, because the more tea scale, the harder it is to clean.

Therefore, daily care cleaning is as important as regular cleaning.

Recommend a few descaling tips

1. Scrub with toothpaste. The toothpaste contains both a detergent and a very fine friction agent. It is easy to wipe off the tea rust without damaging the pot and cup. After wiping, rinse with clean water.

2. Soak the cup with heated rice vinegar or soda water for 24 hours, and then rinse it repeatedly to clean it.

3. Soak the tea cup with concentrated salt water and wash it; or even dip the salt with your fingers and rub it evenly on the tea stains. Rub it to remove the tea stains.

4. It is advisable to use a soft bristle brush or toothbrush, a gentle cleaning cloth, etc. for cleaning.

Because the rough cleaning tools such as steel balls or cleaning balls are easy to damage the enamel on the inner wall of the tea set, the tea scale generated later can easily penetrate into the deep layer of the tea set and it is extremely difficult to completely remove it.

The above method is more suitable for porcelain and glass products.

Soda water has the best effect of removing tea stains, followed by toothpaste and white vinegar, and brine is the worst.

Wiping with a toothbrush alone can also remove tea stains from the inner wall of the teacup, but the effect is relatively slow.

Tea scale is an alkaline substance, and baking soda is sodium bicarbonate. The solution is alkaline. When the tea scale meets baking soda, a hydrolysis reaction will occur and it will become a small molecule easily soluble in water.

As for salt, it is more of a frictional cleaning effect.

Tea dirt is often produced after the residual tea soup has dried.

In order to avoid the accumulation of tea scale, the most important thing is to wash it immediately. Washing the tea set with hot water to make tea immediately after drinking tea is the most labor-saving sanitary habit.
