Is it true that lemon can remove scale?

What is scale? It is actually a layer of white alkaline accumulated on the wall of the kettle for a long time after boiling water. If this layer of alkali is not cleaned in time and poured into a cup, you will find a layer of small white spots floating in the cup. Some careful people have found that lemon descaling is very practical, so the editor will answer for you here, is this method feasible?

experiment:

1. A fresh lemon and a kettle with scale.

2. Boil the water for 5 minutes, turn off the heat and let the lemon soak in the pot for 2 minutes. During this time, you can use chopsticks to stir the lemon water to speed up the dissolution of scale;

3.3. We can see that the scale on the inner wall of the iron pot has become significantly thinner and lighter, but the thicker accumulated scale has not been removed in large quantities.

Explaining: Why lemon is the "nemesis" of scale

Lemon can remove scale on the inner wall of the iron pot to a certain extent. Lemon contains citric acid, which is a weak acid and non-toxic. The main component of scale is carbonate. Under high temperature conditions, citric acid reacts chemically with it and the scale will dissolve in the acid. "The amount of citric acid in a lemon is relatively small, so it is not ideal for removing stubborn scale. When the citric acid content is sufficient, the higher the temperature, the greater the solubility of scale.

In addition, she also told us that the ingredients of the descaling agents sold in supermarkets are mostly citric acid. Because the citric acid in the descaling agents is processed and refined and has a high purity, the descaling effect is very obvious.

Is it true that lemon can remove scale? Through the above explanations, I believe this is a very practical and convenient way to clean scale. Lemon is the "nemesis" of scale, and now this statement is true. Because experiments have proved that when a lemon is boiled in a container, the scale disappears immediately. I also hope that this little method can bring convenience to more people in life.
