The thermos will appear limescale after using it for a while, why does adding vinegar make it disappear? Clean the inside of the thermos flask to dissolve, add vinegar to make it better with white vinegar, if there is no white vinegar, then add vinegar, shake up and down, put it on the inner wall of the thermos flask of sufficient size and vinegar, leave it for a while, when there is no more foam pour out the solution, observe whether the thermos flask has been removed, if not, add some vinegar until it is cleaned, then pour water, clean the thermos flask before use. The main components of scale in a thermos are calcium carbonate and magnesium hydroxide, which are formed when calcium, magnesium ions, and bicarbonate in the water are heated.

The scaling process of water is actually the process of loss of hardness. Although calcium and magnesium ions in water can form scale, they cannot be completely removed because they are essential trace elements for the human body. Calcium carbonate is an important component of bones and teeth, and trace elements in water are more easily absorbed by the body.

So not only can we keep these beneficial trace elements in the water, but we can also prevent the water from scaling? White vinegar and baking soda, add a pinch of rice, shake well and rinse. The answer is yes.

My least favorite is the pot scales, pour white vinegar or old vinegar into a bag, soak in vinegar for five minutes, and then use 100 clean cloths in the kitchen, shake it up and down every five minutes or so, and then rinse it with water, the effect is very good!

The main component of vinegar is acetic acid, also known as acetic acid, which reacts with calcium carbonate to produce calcium acetate, water, and carbon dioxide. Acetic acid reacts with magnesium hydroxide to form magnesium acetate and water. In addition, the lemon fruit that we often eat also has the effect of regulating the scales, if the adjusting scales are not too much in the thermos, we can put two chopped lemons into the thermos, add boiling water, let it stay for a while, and then pour it out.

First put a small amount of white vinegar in the kettle (you can also use old vinegar, but the effect is not as good as white vinegar), then fill the kettle with water, heat and boil, leave it for about an hour, open the kettle and you will find that the scale has dissolved a lot, as long as you use a brush to brush off the residual scale on the side of the kettle, the kettle will become clean.

Because limescale is generally made up of calcium carbonate, vinegar can react with calcium carbonate, so it will disappear.

This is because when vinegar is added, the vinegar reacts with the scale, and then the scale disappears.

Because vinegar is an acidic food.

Vinegar can physically react with the scale peanuts in the thermos, and the vinegar is instantly inhaled into the scale.

Vinegar removes limescale.

If the thermos is used for a long time, a layer of tan substance will be left on the inner wall of the bottle, which is limescale. Internal scale is formed by the accumulation of trace precipitated substances contained in water over a long period of time.

Its main components are insoluble salts and alkalis of calcium and magnesium, which will affect the insulation of the thermos. The scale is very hard and is generally not easy to remove by mechanical methods, but the daily vinegar can remove these scales, and the effect of white vinegar is particularly ideal.

Scale hazards: 1. The thermal conductivity of scale is very poor, which 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 a 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 will be a risk of excessive dissolution of heavy metal ions in drinking water.

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

When vinegar is added, many fine bubbles are formed, and the limescale will quickly fall off and dissolve. Reason: The scale components are mainly composed of calcium carbonate and magnesium carbonate, which can react with acetic acid in vinegar to form carbon dioxide gas and soluble acetate.

Bubbles will occur, indicating that the scale contains carbonates.

1. Use edible vinegar with a larger concentration to descale.

Take the vinegar, pour it into the thermos, don't pour too much, then close the cap, put the thermos horizontally, shake it up and down in a circle, and then leave it for fifteen minutes, which can be flipped twice, so that all sides are soaked in vinegar. Open the cap and rinse with water. until all the limescale has been washed out.

2. Clean up with egg shells.

Crush the red-skinned egg shell with your hand or pat it with something, put it in a thermos with a little tap water, and close the cap. Turn the thermos sideways and shake it from side to side, with a little force, and the egg shell will slowly knock off the scale attached to the bottle wall.

Shake for two or three minutes, open the lid to see, pour water into clean water when the scale is almost removed, if you find that there is scale after cleaning, you can repeat it again, basically the scale can be removed.

3. Descale with baking soda.

You can pour baking soda with a concentration of 1% to descale, pour about one-fifth of the bottle, cover the bottle and shake it up and down, and then leave it for about three minutes. Pour out the baking soda and rinse with clean water.

Take some egg shells and pinch them into blocks, pour them into the thermos, then put a little water, cover the thermos tightly, lift the thermos and shake it up and down, so that the egg shells can fully contact the inner wall of the thermos, so that the white scale in the thermos can be removed several times, and finally the eggshells are poured out, and then rinsed the thermos with water.

Tea bags: Soak the leftover tea bags in a thermos to remove some of the limescale over time. The above three methods are relatively easy to operate, but it is best not to wait for too much scale before starting to clean, it is usually best to treat the thermos once in a while, so that we can drink relatively pure water.

Leave hot water in the white vinegar thermos, pour in some white vinegar, shake the lid several times, and then leave it for a period of time, the scale can also be removed, and finally rinse with water.

Warm bottle limescale is too thick to remove the trick: add the worthless it, clean and fast to remove the dirt.

White vinegar and carbonated drinks are fine.

It's just that you don't soak for enough time or not enough concentration.

The main ingredient of limescale is carbonate such as calcium carbonate, and the acetic acid in vinegar reacts with it to produce minerals and carbon dioxide gas, which are soluble in water.

The main component of scale is carbonate such as calcium carbonate, and the acetic acid in vinegar will react with it to produce minerals and carbon dioxide gas that dissolve in water. Put the white vinegar into 10% of the kettle, then fill it with water, boil it for about an hour, and the scale can be removed.

1.Salt descaling method:

Use 5-10 grams of salt, put it in a boiling water bottle (put some paper scraps when there is a lot of scale), pour in 100 ml of water, then cover the bottle cap, shake it for a while The scale will fall off. Then pour out the limescale and wash the thermos flask with clean water.

2.Vinegar detergent method:

Pour 250 grams of hot vinegar into the boiling water bottle, close the cap tightly, shake it gently and leave it for half an hour to remove the limescale.

3.Liquor descaling method:

Heat an appropriate amount of liquor into a boiling water bottle, soak it for a few hours and pour it out, the scale will fall off, and then rinse it with clean water.

4.Dilute hydrochloric acid descaling method:

Pour 200ml of dilute hydrochloric acid, or 50 baking soda and a glass of water, into a bottle of boiling water and shake gently for a while to remove limescale.

5.Crushed egg shell descaling method:

Put the broken egg shell into a boiling water bottle, pour in a few drops of detergent and an appropriate amount of water, shake it up and down after capping, and finally rinse it off with water.

The steps are as follows:

1. First of all, empty the hot water in the thermos, add vinegar to the thermos, and ensure that the amount of vinegar is just below the bottom of the thermos (thermos).

2. Then cover the thermos stopper, put the thermos horizontally, and then slowly rotate it so that the vinegar is in full contact with the wall of the thermos. Rotate for about 40 seconds, then uncork and pour the vinegar from the thermos.

3. Then fill the thermos with one-third of the thermos. Close the cork, pinch the cork with your hand so that the mouth of the bottle is slightly slit, and shake the thermos. Shake the thermos for about 15 seconds and then pour out the water.

4. Observe that there is no limescale in the thermos. Then repeat the method of the previous step with clean water, and wash it twice. If there is still a small amount of limescale, I dissolve the limescale by repeating the second step with a small amount of vinegar. Then wash it three times with clean water.

Do you put a small amount or soak for a short time? You put a little more and then put the warmth flat. Shake it back and forth so that the gall bottle is full of vinegar.

Vinegar to remove limescale. 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, producing minerals and carbon dioxide gas dissolved in water, white vinegar can be bought in general 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.

After the water bottle is used for a period of time, it will precipitate some scale, the main components of scale are CaCO3 and MG (OH)2, vinegar contains acetic acid, acetic acid can react with calcium carbonate in scale to form soluble acetate, so vinegar can remove scale in the hot water bottle. Here's how their chemistry looks: 2CH3COOH+CAC3 (CH3COO)2CA+CO2+H2O;

2ch3cooh+mg（oh）2→（ch3coo）2mg+2h2o.

Ionic equation. 2ch3cooh+caco3→2ch3coo-ca2+

co2↑+h2o;

2ch3cooh+mg（oh）2→2ch3coo-mg2++2h2o.

Vinegar is a safe and healthy way to remove limescale.
