Why are there tea stains in the cup that often makes tea?

Tea scale is generally produced at the junction of tea and air, and chemical analysis has found that the composition of tea scale is actually quite different from the dried tea solution. In terms of organic matter, the most important component is oxidized polyphenols (also unsightly color **), and in terms of inorganic matter, the most important thing is actually some insoluble calcium salts, such as calcium silicate and calcium carbonate. These poorly soluble ingredients combine to form tea stains that are difficult to clean.

There is no mention of heavy metals, and if there is, there should not be much......It can be seen that the most abundant metallic element in the analysis is calcium.

One of the factors that affect the amount of tea scale is the hardness of water, and hard water is more likely to cause tea scale (high calcium content). In addition, I also saw an article saying that tea with milk forms less tea scale, because the protein and polyphenols are combined.

So how can the tea dirt on the cup be completely removed?

Tea stains on ceramic cups are difficult to remove, salt, alkali, baking soda, vinegar have been tried, and the effect is not ideal.

Usually I like to drink some green tea, jasmine tea. I usually use a clear glass cup instead of a teacup to make tea. Because I like the light fragrance of the glass cup when making tea, and the elegant tea color that can be seen through the glass, it is very comfortable.

And one more point, the glass is open, easy to clean. Tea lovers know that tea-making cups are easy to leave theophylline, and theophylline is not easy to clean. The theophylline on the teacup is not cleaned in time, which affects the mood of drinking tea.

After many experiments, I found that theophylline can be easily washed off with salt.

First of all, wet the teacup, but do not leave any water inside, just leave water droplets on the walls of the cup, this is to allow the salt to stick to the teacup without melting it all. After sticking the salt to the wall of the teacup, grind it slowly by hand, and the fine salt particles can grind off the theophylline attached to the teacup little by little.

At this point, you will notice that the unmelted salt on your fingers has turned yellow. When using salt, you can use a little more, grind the whole teacup once and then clean it with water, check that there is still ** is not clean, you can repeat the action just now.

2. Potato skin, for stubborn tea scale, you can prepare a basin with water, put the tea set in it, then add the potato skin to boil, and then rinse it after cooling. You can also use the potato skin to wipe the place that has not been rinsed, so that the teacup becomes bright as new again, the potato is rich in starch, these starches have a strong adsorption force, but pay attention to soak the potato skin for a long time, and soak the starch out.

3. Toothpaste, presumably toothpaste should be something that everyone will think of as a stain removal product. That's right, that's it. The composition of toothpaste is more complex, it has both a stain remover and a subtle friction agent in it.

We just need to prepare a waste toothbrush, squeeze a small amount of toothpaste, apply it evenly to the area with tea dirt, and wait for 1-2 minutes before cleaning it. It is recommended to use toothpaste containing whitening ingredients for better stain removal effect.

You can use edible salt to remove, pour the salt into the wall of the cup, and then wipe it directly with a cleaning cloth, toothpaste can also be used, squeeze a small amount of toothpaste and apply it to the tea stain, wait for 1-2 two minutes, and rinse it directly.
