(1) Decontamination of sweet potato in kettle.
In the 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 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) boiled eggs to 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.
(4) 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.
⑤ Scale removal due to thermal expansion and contraction.
Put an 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 fill it with cold water quickly, or wrap the handle and spout with a rag and hold it with your hands. Sit the dried kettle in cold water quickly (don't let the 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.
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 scale prevention
Put a clean mask in the kettle. When boiling water, the scale will be absorbed by the mask.
8 magnetization
Putting a magnet in the pot can not only prevent fouling, but also magnetize boiling water and prevent constipation and pharyngitis.
