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 hardness of groundwater is greater than that of 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.
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 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 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.

Tea buying skills
1, tenderness: tenderness is the basic factor that determines quality. The so-called "dry appearance, wet ass" means tenderness. Generally, tea with good tenderness is easy to meet the appearance requirements of this kind of tea (such as "light, flat, flat and straight" in Longjing). In addition, it can also be identified from the presence or absence of tea seedlings. Good pre-seedlings and white hair shows show that they are tender and well-made. If the tenderness of raw materials is poor, no matter how good the workmanship is, there will be no white hairs on the sharp seedlings and tea strips.
2. Cord: Cord is a certain shape and specification of various tea sets, such as fried green ribbon, round pearl tea, flat longjing tea, granular red broken tea and so on. Generally, long strip tea is elastic, straight, strong, thin, round, flat, light and heavy; Round tea depends on the elasticity, uniformity, weight and ethereal degree of particles; Flat tea to see if it is smooth and meets the specifications.
3. Color: The color of tea is closely related to the tenderness of raw materials and processing technology. All kinds of tea have certain color requirements, such as black tea, green tea, oolong tea and black tea. However, no matter what kind of tea, good tea requires consistent color, bright luster, oily and fresh. If the colors are different, the shades are different and dull, it means that the raw materials are old and tender, the workmanship is poor and the quality is poor.
4. Whole crushing: Whole crushing refers to the shape and crushing degree of tea, with flattening as the best and crushing as the second.
