How to remove scale, urgent !! How to deal with scale removal chemistry ?

Add a little vinegar to wash it down, and there are also cleaning liquids on the market that specialize in cleaning scale.

a. The scale in drinking boiling water can be filtered with "Haili conical scale filter screen", which can be filtered by physical methods, and the visible scale, rust, water and alkali impurities can be filtered out, and you can drink it with confidence.

b. The scale on the wall of the pot can be cleaned with "Haili scale", and the pot is not used at night when it is filled with blisters, and it will be completely clean in the morning.

What kind of scale do you want to remove, the above 2 things are available on the Internet, which are very cheap and practical. The two together are only more than 2 yuan.

1. Remove the scale on the wall of the thermos and kettle, and there is Taishan Tiangong scale removal cleaner in **;

Second, to remove the scale in the boiling water, there is a set of 10 yuan of patented products Taishan Tiangong scale filter, easy to remove scale, rust and other sediments and suspended solids in the boiling water.

3. Whether it is a kettle or a thermos, it is easy to remove the scale by cleaning it frequently.

Fourth, special attention should be paid to boiling water with an electric kettle, and the inner wall of the kettle and the electric heating pipe should be cleaned in time after boiling water.

You can pour vinegar or cola, but if not, you can buy the kind of cleaning solution that clears limescale.

The so-called limescale is calcium carbonate, which can be removed by washing with vinegar.

Pour the vinegar into a scaled water bottle, then heat the vinegar until it boils, and then leave it for about an hour before the scaling is dissolved.

It depends on what causes it, generally add some vinegar and bubbles.

1. Edible vinegar to remove scale.

The main ingredient of limescale is calcium carbonate, and the acetic acid in vinegar reacts with it to produce minerals and carbon dioxide gas that dissolve in water. You can mix vinegar and water in a ratio of 1:10, then pour it into a kettle, boil it for about an hour, and finally brush it normally.

2. Remove limescale from egg shells.

Egg shells are also a great way to remove limescale from eating eggs, collect the remaining egg shells, twist them, put them in a limescale container, add most of the water and shake for about 10 minutes. The egg shell simply rubbed against the scale, so that the scale in the container was removed.

3. Use baking soda.

Pour baking soda powder into the kettle and add a small amount of water to make the baking soda powder into a paste, and gently wipe it with a cloth, and the scale will be easily wiped off.

4. Clean with starch.

Starch can also remove scale, as long as some starch content of food, such as yam, potato, etc., as long as their peeled skin into the scale kettle container, pour some water and leave for about half an hour, the adhesion of starch can remove the scale adhesion, but it is not for some hard scale and thick scale.

5. Noodle soup or rice water.

Noodle soup and rice water can be used to remove scale, you can pour the soup or rice water left over from the boiled noodles into the kettle, boil it with electricity, let it stand for half an hour, and wait for the scale to soften and can be easily wiped off.

Precautions: 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.

The main component of limescale is calcium carbonate. Some acids can be added to dissolve calcium carbonate, such as vinegar, or hydrochloric acid. Calcium acetate and carbon dioxide, or calcium chloride and carbon dioxide, are formed, and the scale is dissolved.

Because the main ingredient of limescale is caco, it can be removed by reacting with vinegar. Pour white vinegar or vinegar into a pot, add water to boil, let stand for an hour and then scrub to remove limescale.

To remove scale, then you can use acid to decompose, decompose the scale, scale is generally insoluble in water substances, such as calcium carbonate, as long as acid can be added, the scale can be removed.

How to deal with limescale is very good after half an hour of baking soda and white vinegar.

Scale is a precipitate precipitated by the free calcium and magnesium in the water combined with acid roots to form calcium carbonate and magnesium carbonate during the heating process, mainly calcium salt.

The main ingredient of scale is calcium carbonate, so to use acidic things to deal with it, you can go to the supermarket to buy scale net, pour it on the scale to indicate that it will naturally dissolve after a few minutes, and repeat several times in serious cases.

Boil a pot of water, and when it boils, add vinegar, and it quickly disappears.

If it's in a boiling kettle, add hot water and vinegar, pour it in, and you're done.

None of this works, the key is the issue of water. Soft water will not scale.

The effect of using Dabao brand five cleaning powder is particularly good.

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.

If you are in a supermarket that sells that kind of limescale cleaner, you can just buy a pack. Tear open a pack of limescale detergent and pour it into the container, inject hot water, and fully soak the inner wall of the container in water. If the dirt is particularly stubborn, soak it for a longer time.

If not, here's how:

1. Put some paper scraps in the bottle, then pour in warm salt water, shake gently for a while, and the scale can be removed.

2. You can pour about 500 grams of baking soda with a concentration of 1%, or heat the vinegar into the bottle, shake it gently, and the scale can be removed.

3. Slightly break the two egg shells, put them into the bottle, then fill the half tea jar with cold water, plug the bottle cork and hold it down with one hand, hold the neck of the bottle mouth with your thumb and other fingers, and hold the bottom of the bottle with the other hand, and rotate and shake it up and down, left and right. After about 20 seconds, remove the cork, pour out the eggshell, and rinse twice with water.

4. Use 250 grams of vinegar, heat it and pour it into the hot water bottle, soak it for a few hours, and then shake it up and down, left and right, and the scale in the bottle will fall off.

5. Take 200 grams of dilute hydrochloric acid and soak it in the bottle for a while, and then shake it to remove the scale in the bottle.

6. Pour the water in which the noodles are boiled into the bottle, shake for a few minutes, pour it out, and rinse it with water to clean it.

7. Take some sunshine leaves or pumpkin leaves and cut them into pieces of 3 cm to 4 cm square, put them in the bottle, add a little cold water, gently shake the hot water bottle a few times, pour it out and then wash it with water.

Pour a little vinegar into it and shake it.

Mask to prevent limescale: Put a clean mask in the kettle, when boiling water, the scale will be absorbed by the mask.

Magnetization: Putting a magnet in the pot not only does not accumulate scale, but also magnetizes the boiled water, and also has the effect of preventing constipation and laryngitis.

Kettle boiled potato descaling: In the new kettle, put more than half a kettle of yams, fill with water, cook the yams, and then boil the water later, so that there will be no limescale. However, it should be noted that after boiling the potato, the inner wall should not be scrubbed, otherwise it will lose its descaling effect.

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

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

Boiled eggs to remove scale: The pot of boiling water is hard and difficult to remove after a long time. If you boil eggs twice with it, you will get the desired results.

Thermal expansion and cold contraction to remove scale: put the empty kettle on the stove to boil the water in the scale, boil until there is a crack at the bottom of the kettle or boil until there is a "bang" sound at the bottom of the kettle, remove the kettle, quickly pour cold water, or wrap the handle and spout with a rag, hold it with both hands, and quickly sit the boiled kettle in cold water (do not let the water pour into the kettle). Repeat 2 to 3 times, the scale at the bottom of the pot will fall off due to thermal expansion and contraction.

Vinegar to remove scale: If the kettle has scale, you can pour vinegar into the water and boil for one or two hours, and the scale will be removed. If the main ingredient in the scale is calcium sulfate, the soda ash solution can be poured into the kettle and boiled to remove the scale.

Use a brush dipped in a little toothpaste to clean it, and you can also dip the mosquito coil burned ash brush! The effect is also good!

You can add some vinegar dropwise to it, it is best to add less first, and then add vinegar according to the amount of the gutter. Rinse with water at the end.

Put the potato peel and boil it, and the limescale will fall off.

Add vinegar to soak, preferably for half a day, to help remove.

Soak in warm water for about ten minutes to remove limescale!

If it's a kettle, a thermos or something like that, you can wash it with vinegar.

1. Method 1: Pour the container with scale into the vinegar, pick up the container and shake it, let the vinegar soak the place with scale, shake it a few times, put the container for about 20 minutes, and after 20 minutes, you can find that the scale has begun to fall off. In order to remove the scale more cleanly, you can pour warm water into the container, submerge the place with scale, and soak it for about half an hour, the longer the effect.

After soaking, you can find that the limescale at the bottom of the container is almost all off, just clean the container.

2. Method 2: Slice the lemon and put it in a container with limescale. If the container can be heated, you can heat it to boil the water, and then leave the container untouched for about 10 minutes.

If the container cannot be heated, it can be poured into boiling water and soaked for 20 minutes. The higher the temperature, the better the dissolution. The main component of lemon is citric acid, citric acid is a weak acid, and the weak acid reacts with the scale after heating, causing the scale to fall off.

The more lemons, the higher the acidity, the better the effect.

3. Method 3: Egg shell scale removal. After eating the eggs, you can put the egg shells up, put the egg shells in a container with limescale, add two-thirds of the pure water, and shake for 10 minutes.

The principle of this method is a physical principle, because the egg shell and water rub against the scale with the force of shaking in the container, and the scale can be effectively removed. This method requires the addition of egg shells according to the size of the container.

4. Method 4: starch descaling. For foods containing starch such as potatoes and potatoes, put potato skins and sweet potato skins into a container with limescale, pour water into the container, and leave it for about half an hour.

Because starch has an adhesion effect, this method is suitable for thin scale containers, and it cannot work on very hard scale.

1. Descaling refers to the removal of scale. The main components of scale are calcium carbonate and magnesium hydroxide, which can chemically change with acid, pour some vinegar (the main ingredient CH3COOH, organic acid - acetic acid) in the kettle, warm it on the fire, and the scale will be crushed.

2. Dilute hydrochloric acid (HCl, a strong acid) can also remove scale.

3. Vinegar, pour white vinegar or vinegar into the kettle, the dosage is 10% of the scale of the kettle, add water to boil, let stand for an hour and then wash.

4. Tea leaves, pour tea residue and hot water into the electric kettle, shake it a few times, leave it for half an hour, and the scale will naturally fall off.

5. Baking soda, put a spoonful of baking soda in boiling water, and boil for a few more minutes to remove the scale. Dilute hydrochloric acid, after adding dilute hydrochloric acid to water, shake evenly. Let the hydrochloric acid soak the scale, and the scale can be removed quickly, and it can be washed with water.

1.Baking soda removal: Add water to a boil or soak for 10 minutes.

2.White vinegar removal method: add water to boil and let stand for 1 hour.

3.Potato peel removal: add water and cook for 10 minutes.

4.Lemon juice removal method: add water and let stand for dozens of minutes, then add water to boil and then let stand and wait for the water to cool.

Baking soda is a common thing in our lives, it can clean many things, including the stubborn "stain" of limescale, and it works very well. Baking soda has many uses, in addition to cleaning purposes, it can also assist in raising dough, fluffy cakes, removing yellowing and stains, and refreshing the air in refrigerator cabinets.
