How to remove tea stains from cups? People who like tea have many tea sets. Tea contains tea polyphenols, which easily oxidizes to form tea scale and adheres to the surface of teapots and teacups. How to remove tea stains from cups?

How to remove tea stains from cups? The first method is egg shell.

We can grind the egg skin into pieces. Powdered substances ground from the egg skin began to clean the tea stains on the teacups. This method is very convenient and effective, and it can be washed with clear water after cleaning.

The second method is edible salt.

The main operation steps of edible salt are: put a little water in a teacup with tea stains, and then spread the edible salt evenly on the tea stains by hand. At this time, you will be surprised to find that your fingers are dyed the color of tea. At this time, it means that the tea stains have been washed off, and then washed off with clear water.

The third kind is potatoes.

When we use potatoes, we usually peel them off and throw them away. At this time, you should boil the potato skin in the pot. After boiling water, clean the surface of the teacup with this boiled potato chip water, and then you will find it very easy to remove the stains on the surface of the teacup. Let it stand for about five minutes and wash it with clear water.

The fourth is toothpaste.

Squeeze out toothpaste and spread it evenly on the inner surface of the teacup. Wipe the surface of tea stains repeatedly with steel balls or rags. After three minutes of repeated scrubbing, you will be pleasantly surprised to find that the toothpaste turns yellow, indicating that the tea stains have been washed away. At this time, you just need to wash it with clear water.

The fifth method is soil.

The earth is the most common and common, and this is what you see in the picture. You can dig some soil on the floor of the community, put it in a cup at home, and then scrub the surface with some hard things.

How to remove 2 1 tea stains from cups, toothpaste

Toothpaste, as a necessity in our daily life, is both practical and convenient for cleaning tea stains in tea cups. When cleaning, take a proper amount of toothpaste and brush it with a cup brush in the place where there is tea dirt in the teacup before cleaning.

If you use toothpaste to clean tea cups, especially those with thin cup walls, such as caps, it is recommended to use a cup brush with bristles similar to a toothbrush.

Because the principle of toothpaste cleaning tea stains in teacups depends on tiny friction agents and cleaning agents in toothpaste, sponge-like cup brushes have poor effects and are easy to damage teacups with thin cup walls.

You can also directly prepare a clean toothbrush specially used for cleaning tea cups, which is convenient and easy.

Suitable for: porcelain cups, mugs, teacups, fair cups, metal cups and most glasses with less tea stains.

Note: purple sand cups and corresponding purple sand utensils, especially those with good sand texture, are not suitable, because toothpaste contains corresponding sweeteners, detergents and humectants, which are necessary for cleaning teeth and are harmless to the body. However, ceramic utensils have certain pores and are easy to absorb, which will affect the taste of tea in the later period.

2. vinegar

The method of brushing teeth with toothpaste and cup brush is more suitable for cleaning teacups with relatively little tea scale and scale. If there are many tea stains on the teacups, the cleaning effect will not be ideal, and if there are many teacups to be cleaned, it will be more troublesome and laborious.

At this time, you can use vinegar to clean it. The main components of tea scale are calcium carbonate and magnesium carbonate, which can be decomposed by acetic acid in vinegar.

If the tea scale is large and thick with good adhesion, it will not fall off easily. First, put the teacup into the corresponding utensils, add hot water and soak it in vinegar (white vinegar is recommended to avoid affecting the color of the teacup;

Acetic acid in vinegar is volatile. In order to ensure the cleaning effect, it is best to choose a soaking appliance with a cover and good sealing. The amount of vinegar added is determined according to the amount of scales or tea scale (the more tea scale, the more vinegar).

Soak 10~30 minutes, then take it out and clean it. The soaking time depends on the amount of tea dirt and the cleanliness of the teacup. If there are too many tea stains and the soaking effect is limited, you can heat it properly, and use a small fire when heating to avoid the damage caused by boiling hot water and the cup touching the heating appliance.

Suitable for: porcelain teacups and glass teacups, with thin walls and many tea stains, which are not easy to clean.

Note: Ceramic products such as purple sand and purple pottery should not be cleaned with acid-containing substances such as vinegar and lemon.

Because first, purple sand and purple pottery have pores, which will suck vinegar and affect the taste of drinking tea.

Second, there is acetic acid in vinegar and citric acid in lemon, and acid is easy to corrode ceramic products such as purple sand.

3. tea seed powder

① Due to its pore structure, purple sand teacups are more prone to tea stains if they are not for potted plants. Clean the tea dirt in the purple sand cup. Do not use chemical detergent and acidic detergent to avoid damaging the purple sand pot.

Purple sand cups can be boiled in boiling water for a period of time, and then washed with tea seed powder.

If it is a purple sand cup with good sand texture, don't use too much force when cleaning it, or use a rough cup brush and tea towel to avoid damaging the sand beauty of purple sand.

Purple sand cups are generally recommended to be brewed with hot water immediately after drinking tea to avoid the accumulation of tea scale or scale.

(2) If the cups and glasses are pottery, they can be washed directly with tea seed powder. Friends of Nanming Jiaren usually use Pu 'er tea seed powder when cleaning cups and covering bowls.

Suitable for: ceramic teacups such as purple sand and purple pottery with porous structure.

Note: Don't use too much force and roughness when cleaning the purple sand cup, and avoid using chemical detergents and acidic detergents.

How to remove tea stains from cups 3 1, potato/egg shell descaling method

First pour about half a cup of hot water into the thermos cup, dice the potatoes, put them into the thermos cup, then tighten the lid and shake it up and down for two minutes. Open the cup, pour out the water and diced potatoes, and then rinse with clean water. You will find that the tea scale attached to the cup wall is obviously less, and you can remove the tea scale by repeating it several times. If you don't have potatoes on hand, you can also use broken egg shells instead. The operation steps are the same.

Put a slice of lemon when making tea.

Some foreign researchers have found that the tea scale formed by soaking one bag of British black tea at a time is more than that formed by soaking two bags at a time, and the tea scale is not formed by soaking five bags at a time. This is probably because polyphenols in tea make the PH value of tea soup drop. Another patent achievement is that a small amount of citric acid is added to the tea bag to adjust the taste and reduce the tea scale.

In addition, calcium ion is the key factor to form tea scale, which promotes the oxidation reaction of tea polyphenols and plays a cross-linking role in the polymerization process. The harder the water is, the more tea stains there are, the harder the groundwater is than the surface water, and the tea stains formed by making tea with pure water will be much less. When you make tea with tap water, you can boil the water for a few minutes, and the calcium and magnesium inside will form carbonated soda, which will reduce the formation of tea scale.

3, citrus peel to a cup of tea dirt method

After eating oranges, everyone will throw away the orange peel, but here, I want to tell you that wiping the teacup with orange peel can remove tea stains. For the teapot, we can boil it with orange peel or citric acid, and then we can clean the teapot residue 2-3 times.

4, salt/toothpaste descaling method

You can prepare a clean toothbrush, soak the bristles of the toothbrush, dip them in some salt, then put the toothbrush into the cup and scrub the cup wall carefully, which is very effective in removing dirt. If you don't have salt on hand, you can 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 salt or toothpaste and wrap it on chopsticks. Then, put the chopsticks into the bottom of the thermos and stir them back and forth several times.
