How to remove scale in the kettle? We all know that when the kettle is used for a long time, it will produce a lot of dirt, which needs to be cleaned and used again, otherwise it will be bad for health. So how to remove scale in the kettle?Scale is due to the fact that some containers that are often in direct contact with water have been used for a long time, and a thick layer of impurities grows on the inner wall.
The general scale formation is caused by the fact that after the container is burned several times, the calcium sulfate (CaSO4) containing slightly soluble in water precipitates due to evaporation of water, and the originally dissolved calcium hydrogencarbonate (Ca(HCO3)2) and carbonic acid. Magnesium hydride (Mg(HCO3)2), which decomposes in boiling water, releases carbon dioxide (CO2), and forms insoluble calcium carbonate (CaCO3) and magnesium hydroxide (Mg(OH)2), which is also precipitated. Generate MgCO3. This creates scale.
How to remove scale in the kettle:
Descaling agent
Now there are special descaling detergents or powders on the market. Many ingredients are also very healthy. If you are a lazy person, you can buy this descaling product directly and put it in the inner pot of the electric kettle. With a light bubble, the scale can be easily removed, which is very convenient.
Vinegar descaling
In addition to the special descaling agent, in fact, many daily seasonings in the family can also remove scale. If the kettle has scale, you can put a little vinegar into the water and burn it for one or two hours. If the main component in the scale is calcium sulfate, the soda ash solution can be poured into a kettle to cook and descale.
Lemon descaling
Buy a slice of lemon, slice it, put it in a kettle and cook it once, let it sit for a while, then cool it and then pour it off, the scale inside it will fall off. This method is more reliable and very convenient and healthy.
Baking soda to remove scale
Baking soda is also a small helper to the electric kettle scale. First use a kettle to boil a pot of boiling water. After the water is opened, put a spoonful of baking soda. After boiling for a few more minutes, the scale can be removed. Or pour 500 grams of baking soda with a concentration of 1%, shake the kettle, and remove the scale.
Precautions for using the kettle:
The kettle should be placed on a level surface. After turning on the power, press the water switch. At this time, be sure to add water to the pot. Remember to dry. Moreover, the water should not be too full, and the water surface should be 2~3 cm below the water level of the spout, so as to prevent the water from overflowing outside the pot and drenching the base, causing leakage. Be sure to turn off the power after the water is turned on, and then unplug the power plug before pouring water.
The electric kettle boils water because of its high thermal efficiency. The kettle boils a pot of water, only about 3-5 minutes, so pay attention to the time of water opening. After the kettle is used for a period of time, the kettle will be covered with a layer of white scale. The amount of scale is between 300 and 500 grams. The time required to boil a pot of water is about 4 to 7 minutes. It greatly increases the power consumption. In addition, scale can have a bad influence on the human body. Therefore, descaling treatment is required after a break time.
The kettle and the thermos in the home are covered with scale. The main components of the scale are calcium carbonate and magnesium hydroxide, which can change chemically with acid. According to this principle, in the kettle, pour some citric acid or a commercially available citric acid descaling agent (cooking vinegar can also be used), warm it on the fire, and see the small bubbles on the scale, the scale will quickly Dissolved. The scale in the thermos bottle is removed, and it's no problem.
