The electric kettle for boiling water should be descaled regularly, because the scale affects the heat transfer, and there is too much scale, which may also cause an explosion due to uneven local heating.
Strictly speaking, a simple scale is harmful to the human body, but it is absolutely acceptable to the human body and will not cause any specific harm. However, the scale deposited for a long time contains many sediments, accompanied by trace metal elements produced in boiling water containers, including lead, zinc, arsenic and other heavy metals harmful to human health.
The harm of scale
A layer of white soda water on the inner wall of the kettle contains many harmful elements such as mercury, cadmium, lead and arsenic. In addition to calcium carbonate and magnesium carbonate, if they are not removed in time, harmful elements will accumulate and be re-dissolved in water after being repeatedly used for boiling water and water replenishment. People who drink it will enter the human body, which will cause chronic poisoning, even carcinogenesis and teratogenesis, which will seriously endanger human health.
Here are some ways to teach you how to remove the scale from the kettle.
1, lemon descaling
Chop a lemon and boil it in a pot. After soaking for a period of time, the scale is easy to remove. Supermarkets also have special detergent, the main ingredient of which is citric acid, which has the same effect as lemon.
2. Boil sweet potatoes to remove scale
In a new kettle, put more than half a pot of sweet potato, fill it with water, cook the sweet potato, and then boil the water, so that scale will not accumulate. However, it should be noted that do not scrub the inner wall of the kettle after cooking the sweet potato, otherwise it will lose the descaling effect. For the old kettle that has been covered with scale, after being boiled once or twice by the above method, not only the original scale will gradually fall off, but also it can prevent the scale from accumulating again.
3, baking soda in addition to scale
When boiling water in an aluminum pot with scale, add 1 teaspoon baking soda and boil for a few minutes, and the scale will be removed.
4. Boil eggs to remove scale
It is difficult to get rid of the pot that boils water after a long time. If you use it to cook eggs twice, you will get the ideal effect.
5, potato skin descaling
After a period of use in aluminum pot or aluminum pot, there will be a thin layer of scale. Put the potato skin into it, add appropriate amount of water, boil it, and take it out for about 10 minutes.
6, thermal expansion and cold contraction in addition to scale
7. Put the empty kettle on the stove to dry the water on the scale until there is a crack or a bang at the bottom of the kettle. Take off the kettle and quickly fill it with cold water, or wrap the handle and spout with a rag, hold it with both hands, and quickly sit the dried kettle in cold water (don't let water fill the kettle). Repeat for 2 to 3 times, and the scale at the bottom of the pot will fall off due to thermal expansion and cold contraction.
8, vinegar in addition to scale
If the kettle has scale, you can put a few even vinegar in the water and burn it for an hour or two, and the scale will be removed. If the main component of the scale is calcium sulfate, the soda solution can be poured into the kettle for cooking to remove the scale.
9. Mask scale prevention
Put a clean mask in the kettle. When boiling water, the scale will be absorbed by the mask. Magnetizing descaling Putting a magnet in the pot not only does not scale, but also magnetizes boiling water, and also has the function of preventing constipation and pharyngitis.
10, put the kettle with scale on the stove or induction cooker for a period of time. This method is simple and easy to use. As long as you put the kettle on the stove for a while, the scale in the kettle will automatically fall off. Then take it off and pat it gently.
1 1. The scale remover sold in the market can also remove scale well.
Tips: If you are using a new kettle, I suggest you clean it with steel balls as soon as you find a small scale spot in the kettle, so that no matter how long the kettle is used, there will be no scale in the kettle. Be diligent.
