How to remove limescale from a kettle, tips on how to remove limescale from a kettle

The kettle should be a very common electrical appliance in our lives, usually living in the dormitory, there is no water dispenser, so you can only use the kettle to boil water to drink, but I found that the kettle will deposit a lot of yellow-white scale at the bottom of the kettle after a period of time, it looks dirty, and it takes longer and longer for the water to boil, but I and my roommates will use these 4 small methods every time to remove the scale in the kettle, and the kettle will be like new after use.

1. Aged vinegar. Most people only know that vinegar can remove limescale, but they certainly don't know that aged vinegar is the best way to remove limescale. We can pour some aged vinegar that can cover the scale and put it in the kettle, then plug it in and boil, let it stand for half an hour, and after the vinegar softens the scale, you can easily wipe the scale off with a towel.

2. Potato peels.

Potato skin is also a good thing to remove scale, we can put the peeled potato skin into the kettle, then add water that can cover the scale and potato skin, turn on the power to let it boil, then stir with chopsticks for 5 minutes, and then let it stand for about 20 minutes, you can soften the scale, and finally wipe the scale clean with a clean cloth and rinse it with water.

3. Cold water. Many people don't understand, how can cold water remove scale? In fact, we can use the principle of thermal expansion and cold contraction to make the scale peel off naturally.

The specific method is to first prepare a basin of cold water, connect the empty kettle to the power, let it dry boil, when we hear a violent sound in the kettle, we cut off the power supply, pour cold water into the kettle, and then repeat this process about 3 to 5 times, the scale will fall off by itself.

4. Noodle soup.

We can pour the soup or rice water left over from the boiled noodles into the kettle, then boil it with electricity, and let it stand for half an hour, and then it can be easily wiped off when the scale softens.

If you want to slow down the siltation of limescale, we can put a magnet on the bottom of the kettle, which can not only reduce the deposition of limescale, but also soften the water quality and make the water drink healthier.

After the kettle has been used for a long time, there will be large limescale on the inner wall, so how to deal with it to clean it? Today I will teach you a little trick to remove it easily.

The kettle has been used for a long time and there is a lot of scale, teach you a trick, and the scale will run out by itself.

1. Lemon scale: Prepare a lemon, chop it, then put it in the kettle and boil it with water, let it soak in boiling water for a period of time and then pour it all out, so that you can easily remove the scale in the kettle.

2. Vinegar scale: this method is the simplest and most practical method, the main component of scale is calcium carbonate and other carbonates, the acetic acid in the vinegar will react with it to produce minerals and carbon dioxide gas dissolved in water, white vinegar can be bought in supermarkets, put 10% of the scale of the kettle white vinegar, and then fill it with water, boil it for about an hour, and then brush it, aged vinegar can also be, but the effect of aged vinegar is not as good as white vinegar.

3. Boiled eggs to remove scale: the general electric kettle, after a long time of hard and difficult to remove the scale, if you want to remove the scale, just boil a few eggs in the kettle every morning, because the composition of the egg shell contains calcium carbonate, and after the chemical reaction with the components in the scale, it is much easier to remove the scale, wipe it off.

4. Baking soda to remove scale: baking soda is also to remove scale from electric kettle, generally the heating plate of electric kettle is made of aluminum, when boiling water in the electric kettle, it is easy to form scale, generally we can put 1 teaspoon of baking soda, boil for a few minutes, and the scale will be removed. Or you can pour about 500 grams of baking soda with a concentration of 1%, shake it gently, and the scale can be removed.

5. Yam to remove scale: After the kettle is bought, put the potato into the new kettle, put about half a pot of potato, and then fill it with water to boil, so that if you boil water in the future, it will no longer produce scale, saving trouble and effort. However, it should be noted that after the potato is cooked, do not clean the inner wall of the kettle, which will lose the effect of removing limescale.

Extended Content:

Water scale, commonly known as "water rust and water alkali", refers to the white lump or powder substance gradually formed by the mineral contained in hard water after boiling in the container (such as pot, pot, etc.), and the main components are calcium carbonate, magnesium carbonate, calcium sulfate, magnesium sulfate, calcium chloride, magnesium chloride, etc. The thermal conductivity of scale is very poor, if the scale formed in the boiler is too thick, it will lead to a decrease in the efficiency of the boiler, and in the worst case, it will cause the boiler to burst and cause a boiler accident.

Hazards of limescale:

1) The poor thermal conductivity of scale will lead to the deterioration of heat transfer on the heating surface, thus wasting fuel or electricity.

2) If the scale adheres to the heating surface of the thermal equipment, it will endanger the safe and economical operation of the thermal equipment. Because the thermal conductivity of limescale is very poor, it hinders heat transfer. The heat absorbed by the furnace tube from the flame side cannot be well transferred to the water, and the cooling of the furnace tube is affected, so that the wall temperature rises, causing the furnace tube to bulge and cause the burst pipe.

3) When the scale is cemented, a large number of heavy metal ions are often attached, and if the container is used to hold drinking water, there is a risk that the heavy metal ions will be dissolved too much in drinking water.

4) When limescale fragments enter the stomach, they react with hydrochloric acid, releasing calcium and magnesium ions, which are necessary for stone formation, and carbon dioxide. The latter can cause flatulence and discomfort, and patients with gastric ulcers may also be at risk of gastric perforation.

Ways to remove limescale from kettle:

1. Dip some baking soda with a damp rag, then wipe the area with limescale, and finally rinse it with water;

2. Add an appropriate amount of vinegar to the kettle, and use the weak acidity and alkali of the vinegar to react, which can be heated to promote the dissolution of scale;

3. Pour two cups of water into the kettle, squeeze some lemon juice into it, leave it for half an hour, and then boil it with electricity;

4. Pour a cup of white vinegar into the kettle, then pour half a pot of water, and after boiling, the scale will be gone.

Causes of limescale formation:

1. The water is constantly heated and evaporated and concentrated, resulting in an increase in the concentration of calcium and magnesium salts in the water, and when their concentration is exceeded, it will precipitate from the water to form a precipitate.

2. The water is heated, and the bicarbonates are decomposed by heat to form insoluble precipitate, that is, to form scale.

3. As the temperature increases, the solubility of some salts gradually decreases, and precipitates out. Acrobatics in tap water and dirt formed after the death of microorganisms produced by water heaters due to long-term use. Sediment, impurities, and dirt adhere to the walls of the tank and vacuum tube, forming dissolved scale.

If the kettle is used for a long time, there will be a layer of white scale inside the kettle, which is not easy to clean. Try filling a pot of strong salt water and vinegar before going to bed at night, and brush it with a steel brush and some dish soap the next morning. The scales fall off easily.

There are several simple and easy-to-do methods. You can also try it.

Put the sweet potatoes in a pot and boil to remove limescale. Put more than half a pot of sweet potatoes in a new kettle, fill it with water, cook the sweet potatoes, and boil the water later so that there will be no limescale accumulation. However, it should be noted that after the potatoes are boiled in the pot, the inner wall should not be scrubbed, otherwise the descaling effect will be lost.

For the old kettle that has been full of limescale, after boiling it once or twice with the above method, not only will the original scale gradually fall off, but also play a role in preventing the scale from accumulating again.

Baking soda descaling When boiling water in an aluminum kettle with limescale, add 1 teaspoon of baking soda and boil for a few minutes to remove the scale.

Boil the eggs, remove the scales and bring the water to a boil. Over time, limescale is difficult to remove. If you boil eggs twice with it, you will get the desired results.

Potato peel descaling aluminum pot or aluminum pot will have a thin layer of limescale after being used for a while. Put the potato skins in, add an appropriate amount of water, bring to a boil, cook for about 10 minutes, and remove them.

Scales are removed by thermal expansion and contraction. Place the empty kettle on the stove to dry the water in the limescale. When there is a crack or pop in the bottom of the pot, remove the pot and quickly fill it with cold water, or wrap the handle and spout with a rag and hold it with both hands and quickly sit the dry pot into the cold water (do not let the water pour into the pot).

Repeat 2 to 3 times, and the scale at the bottom of the pot will fall off due to thermal expansion and contraction. (Be careful with this!) )

Remove limescale with vinegar. If the kettle has limescale, put some vinegar in the water and boil for an hour or two to remove the limescale. If the main ingredient in limescale is calcium sulfate, you can pour the soda solution into a kettle and boil it to remove the limescale.

Masks to prevent limescale build-up. Put a clean mask in the kettle. After the water is boiled, the limescale will be absorbed by **.
