Put more than half a pot of sweet potato, fill it with water, cook the sweet potato, and then boil the water, so as not to accumulate scale. 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.
(2) Baking soda descaling 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.
3 Boil the eggs and scale the boiling pot. After a long time, it will be difficult to scale. If you use it to cook eggs twice, you will get the ideal effect.
(4) Scale removal of potato skin After being used in aluminum pot or aluminum pot for a period of time, 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.
⑤ Thermal expansion and cold contraction remove scale. Put the empty kettle on the stove to dry the water in the scale. When the bottom of the kettle cracks or bursts, take it off and quickly inject cold water, or wrap the handle and spout with a rag, hold it with both hands, and quickly sit the dried kettle in the cold water (don't let water inject into 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.
6 vinegar descaling 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.
⑦ Mask In order to prevent scaling, put a clean mask in the kettle. When boiling water, the scale will be absorbed by the mask.
⑧ Magnetization Put a magnet in the pot, which not only does not scale, but also magnetizes boiled water, and has the function of preventing constipation and pharyngitis.
Many people like to drink tea, but the tea stains on the cups are difficult to remove. A layer of tea scale growing on the inner wall of tea set contains metal substances such as cadmium, lead, iron, arsenic and mercury. They bring eggs into their bodies when they drink tea, but in food.
White matter, fat, vitamins and other nutrients combine to form insoluble precipitate, which hinders the absorption of nutrients. At the same time, these oxides can also cause diseases and dysfunction of nervous, digestive, urinary and hematopoietic systems, especially arsenic and cadmium can cause cancer, cause fetal malformation and endanger health. Therefore, people who have the habit of drinking tea should always clean up the tea dirt on the inner wall of the tea set in time. In order to make you stop worrying about this matter, here are some ways to remove tea stains:
(1) Remove the tea scale on the metal tea partition. When using metal tea partition, it will turn black due to 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 tea stains from teacups or teapots. If teacups and teapots are used for a long time, a large number of tea stains are rubbed with sponge dipped in salt, which is easy to remove.
(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.
