How to remove scale from egg shells? The principle of removing scale from egg shells

Many people throw away the eggshells when eating eggs, but some people say that eggshells have a high utilization value and can remove scale from kettles. So how can eggshells be used to remove scale? I will take you to find the answer and also let you understand the principle of eggshell descaling.

How to remove scale from egg shells

1. To use egg shells to remove scale in the kettle, you need to first smash the collected egg shells with a spoon or other hard objects, then put them in a basin, add appropriate amount of clean water, and wash all the remaining egg white on them. Then put the washed egg shells directly into the kettle with scale.

2. Fill the kettle with clean water, then turn on the power supply or put it on the fire to heat it. Turn off the fire after the water boils. After turning off the fire, you can use chopsticks or a spoon to stir the egg shells inside, then put the lid on, put it on the fire again to heat and boil, then let it cool down, pour out the mixture inside, add clean water and continue to heat and boil, then pour out the boiled water. At this time, you will find that the scale inside has disappeared.

The principle of egg shell descaling

1. There are also a lot of calcium carbonate in eggshells. This substance is highly active in high temperature environments. It can promote the decomposition of scale on the kettle and separate it from the inner wall of the kettle, making the kettle particularly clean. In addition, when using eggshells to remove scale from the kettle, adding a small amount of table salt can make its cleaning effect even better.

2. There is another theory about the principle of using eggshells to remove scale. It is said that eggshells are relatively hard in texture. During the heating process, they will scrape against the inner wall of the kettle, and the scale on the inner wall of the kettle will be scraped off during the scraping process. After people pour out the eggshells, they put in an appropriate amount of clean water, heat it to a boil, and then pour it out again to rinse off the scale inside.

The above introduces some methods and techniques of removing scale with egg shells, and also allows everyone to understand the principle of removing scale with egg shells. In the future, when you want to remove scale from the kettle at home, you can use the unwanted egg shells at home to deal with it.
