What are the methods to remove scale from a kettle

When we boil water, we usually use a kettle. After a long time, a layer of white scale will appear on the inner wall of the kettle. When using it, it will not only cause a waste of fuel, but also affect the water quality. This requires us to remove it in time. There are many methods. We must pay attention to the correctness of the use method. Let’s take a look at what are the methods to remove scale from the kettle?

Lemon descaling method

Cut a lemon into pieces, put it in the kettle, boil it and soak it for a while, and the scale can be easily removed. Supermarkets also sell special descaling cleaners, the main ingredient of which is citric acid, and has the same effect as lemon.

Descaling by boiling sweet potatoes

Put more than half of the sweet potatoes in a new kettle, fill it with water, and cook the sweet potatoes. Next time you boil water, there will be no scale accumulation. But be careful not to scrub the inner wall of the kettle after boiling sweet potatoes, otherwise the descaling effect will be lost. For old kettles that are full of scale, after boiling them once or twice using the above method, not only will the original scale gradually fall off, but it will also prevent scale from accumulating again.

Descaling with baking soda

When boiling water in an aluminum kettle with scale, add 1 teaspoon of baking soda, boil it for a few minutes and the scale will be removed.

Descaling with boiled eggs

The scale on the kettle that is used for boiling water becomes hard and difficult to remove after being used for a long time. If you use it to boil eggs twice, you will get the desired effect.

Descaling with potato peels

After using an aluminum kettle or pot for a period of time, a thin layer of scale will form. Put the potato peels in it, add appropriate amount of water, bring to a boil, and cook for about 10 minutes before removing them.

Thermal expansion and contraction to remove scale

Place the empty kettle on the stove to dry out the moisture in the scale. When cracks appear on the bottom of the kettle or a "bang" sound is heard from the bottom of the kettle, remove the kettle and quickly pour in cold water. Or wrap the handle and spout with a rag, hold it with both hands, and quickly place the dried kettle in cold water (do not let water pour into the kettle). Repeat 2 to 3 times and the scale on the bottom of the pot will fall off due to thermal expansion and contraction.

The above is an introduction to how to remove scale from kettles. In normal times, we should also pay attention to the correct usage methods. After discovering scale, do not remove it in serious cases. Generally, it should be removed immediately after it appears. In addition, we should also pay attention to the correct removal methods. The above methods can be used.
