How to remove white floating objects after tap water is boiled?

This may be because the source water of tap water comes from underground, the hardness of underground water is higher than that of river water and river water, and the content of calcium and magnesium ions in water is also slightly higher. After water is heated, calcium and magnesium ions will be separated from water to form a white lens (composed of calcium carbonate and magnesium carbonate), which is a normal phenomenon. At normal temperature, calcium and magnesium ions in tap water are completely dissolved in water, so there is no way to filter it at present, and it is generally difficult to avoid white floating objects.

Here are a few small ways to remove white floating objects in water:

First, a small group of absorbent cotton is wrapped in gauze, or a section of peeled, seedless and washed coarse silk pulp is put into the pot when boiling water, so that water and alkali will be adsorbed on the cotton ball or enter the silk pulp, and the scale at the bottom and wall of the pot will be less; After a period of use, there is a lot of water and alkali in cotton balls and pulp, which can be taken out and washed with water, reused or replaced with new ones in time. The simplest thing is to use the water purification facilities at home.

2. Put the apples and hawthorn into the descaling pot, plug the lid and spout tightly, and leave it for about 10 days, so that the water and alkali in the pot can be easily removed after it becomes soft; If the apple peel and hawthorn are cut open and boiled in water for an hour or two, the descaling effect will be faster. Put some potatoes in the pot and cook for a few hours, and the scales will crack and fall off.

Third, putting a magnet in the pot and boiling water can also make the scale crack and fall off.

Note: Never use vinegar essence or white vinegar, because vinegar contains substances that adsorb water alkali, and there is no water alkali in the surface boiling water, but people will drink water alkali contained in vinegar when drinking water, which will aggravate the harm of water alkali.

Fourth, boil the sweet potato in a kettle to remove the scale. In the new kettle, put the sweet potato in more than half a kettle, fill it with water, cook the sweet potato, and then boil the water later, so as not to accumulate scale. However, it should be noted that after the sweet potato is cooked in the kettle, the inner wall should not be scrubbed, otherwise the descaling effect will be lost. 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.

5. Baking soda can remove 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.

Six, boiled eggs in addition to scale, boiling water pot, used for a long time, scale is difficult to remove. If you use it to cook eggs twice, you will get the ideal effect.

Seven, potato skin in addition to scale, aluminum pot or aluminum pot used 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.

Eight, thermal expansion and cold contraction to remove scale. Put the empty kettle on the stove to dry the water in the scale. When the bottom of the kettle cracks or there is a "bang", remove the kettle 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 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.

Nine, vinegar in addition to scale If the kettle has scale, you can put a few spoonfuls of 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.
