The method of removing tea stains from stainless steel cups, drinking tea is something that many people usually like to do, but many people often do not pay attention to cleaning the tea stains in stainless steel cups when using them, which is harmful to human health. The following is the method of removing tea stains from stainless steel cups.
Method of removing tea stains from stainless steel cups 1 tools/raw materials
Edible salt, vinegar, toothpaste
Small brush rag
Methods/steps
The first one is cleaned with edible salt, which is available in every kitchen and has a low cost. Put the salt in a stainless steel cup with tea stains and brush it back and forth with a small brush or rag until the tea stains are removed. A little hot water can be added in the process of brushing tea dirt, and the effect of removing tea dirt will be better.
The second is to clean it with vinegar, which is also available in every kitchen. First heat the cup with hot water, then pour proper amount of vinegar according to the size of the stainless steel cup, and then wash it with a brush after 4~5 minutes.
The third kind is washed with toothpaste. Toothpaste is not as effective as the first two, but it can also clean tea stains. First, apply toothpaste evenly on the inner wall of the stainless steel cup, and then brush out the foam with a brush. Just wait 5. 10 minutes, and the tea stains can be cleaned.
Method/Step 2
After cleaning, there is a clean stainless steel cup.
Matters needing attention
Try cleaning in the washbasin cabinet or kitchen.
Methods of removing tea dirt from stainless steel cups 2. Skills of cleaning tea dirt
1, wipe with potato skin
Usually when cleaning the tea stains on the tea set, you can use chopped potato skin to wipe the part λ stained with tea stains, because there is still a lot of starch on the potato skin, which is easy to decompose the tea stains and stick to the surface of the potato skin. After all the tea stains are cleaned, you can clean the tea set with clear water.
2. Toothpaste cleaning
Toothpaste is a necessary daily necessities for every household. It can be used not only for brushing teeth, but also for cleaning tea stains on tea sets. After the tea set is contaminated with tea stains, you can apply a proper amount of toothpaste directly on the surface of the tea set, then brush it back and forth with a soft brush to easily wash off the tea stains, and finally rinse it with clear water.
How to get rid of tea dirt when it is soaked?
1, there are many ways to clean tea stains in daily life. If you don't want to wipe it with toothpaste or potato skin, you can also take a proper amount of baking soda and put it in a clean tea set, then pour it into boiling water for a while, and you will find that the tea scale has been naturally decomposed by baking soda and completely dissolved in water, and then wash the tea set by hand.
2. When cleaning, add a proper amount of white vinegar to the tea stains, and then soak them in a proper amount of water for a while, which can also make the tea stains easy to peel off and make the tea set particularly clean. After pouring the water with vinegar, rinse the tea set with clear water, which will make the tea set look as clean as new.
Method of removing tea dirt from stainless steel cup 3 Will tea dirt cause harm to the body?
Tea scale is produced by the oxidation of tea polyphenols, so people who drink tea need not worry.
Kai Zhong, a doctor of food safety, published in Beijing Youth Daily that tea scale contains heavy metals, which will lead to premature aging? It is pointed out that the main component of tea scale is tea polyphenols, and a small amount of metal ions participate in the formation of tea scale. Elemental analysis shows that most components of tea scale are carbon and oxygen, which are derived from polyphenol polymers, and a small amount of elements such as potassium, calcium, magnesium, aluminum, zinc and selenium.
Metal elements mainly exist in the form of water-insoluble carbonate or hydroxide, in which calcium is the main promoting factor for the formation of tea scale, mainly from the water used for making tea. Heavy metal pollutants such as lead, arsenic, cadmium and mercury are not the main metal elements of tea scale, so people who drink tea need not worry.
Tea scale is a polymer produced by tea polyphenols under the action of air oxidation, so it is mainly formed near the waterline and attached to the inner wall of the container. The components of tea scale formed by different types of tea are basically similar. Because green tea contains more polyphenols, it is easier to form tea scale, while deep fermented black tea and black tea have less tea scale.
The research shows that the molecular weight of polymer in tea scale increases gradually with the passage of time, which means that the polymerization of tea polyphenols is still slow. Therefore, it makes sense that the longer tea stains are, the less likely they are to be removed.
How to easily remove tea stains?
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, and the hardness of groundwater is greater than that of surface water, so 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.
Method for shell potato/eggshell
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.
Descaling method of salt/toothpaste
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.
Method for remove tea stains on cup with citrus peel
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.
(1) Remove the tea dirt on the metal tea partition: When using the metal tea partition, it will turn black due to the tea dirt. If it can't be washed off with a medium-sized cleaner, it can be soaked in vinegar or easily cleaned with bleach.
(2) Remove the tea stains on the teacups or teapots: When the teacups and teapots are used for a long time, there will be many tea stains, which can be easily removed by wiping them with a sponge dipped in salt.
(3) Except for small pieces of tea dirt, it can be soaked in the solution of bleach or cleaning powder and left overnight to remove the tea dirt.
(4) Can be scrubbed with toothpaste or broken egg shells, and then rinsed with clear water.
(5) Put a teaspoon of orange powder or orange juice in the teacup and teapot, fill it with clear water and let it stand for 2-3 hours, so that the tea scale loses its adhesion with the tea set and can be easily removed.
