Limescale removal tips, how to remove limescale tips

Here are a few tips for removing dirt:1. Vinegar, pour white vinegar or vinegar into the kettle, the dosage is 1% of the scale of the kettle, add water to boil, let stand for an hour and then wash.

2. 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.

3. Baking soda, put a spoonful of baking soda in boiling water, and boil for a few more minutes to remove the scale.

1 Vinegar to remove limescale.

If there is limescale in the kettle, you can pour vinegar into the water and boil for one or two hours to remove the scale. 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.

2 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.

3. 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.

4 Lemon limescale remover.

If there is limescale in the kettle, you can buy a lemon back, chop the lemon and put it in the kettle, add water to boil and soak for a while, and the citric acid in the lemon can easily remove the limescale.

5. The egg shell can also remove scale, after the egg shell is broken, it is packed in the electric kettle, then add a little detergent and an appropriate amount of water, block the mouth of the kettle with a bottle stopper, rotate and shake, and then rinse it with clean water, and the scale in the stainless steel electric kettle can be rinsed away soon.

6. Tea not only has the effect of making tea, but also can remove scale. Soak them in water and the limescale will fall off slowly.

Scale is caused by the container containing water after boiling water for many times, the water contains calcium sulfate slightly soluble in water due to the evaporation of water and precipitation, and the water decomposes sodium bicarbonate and magnesium bicarbonate sound in the boiling process, resulting in the formation of insoluble calcium carbonate and magnesium hydroxide after precipitation. Therefore, scale is alkaline, and some acidic substances in our household can be used to remove scale.

Baking soda cleaning method: first spread the baking soda evenly inside the kettle, (you can put more after the limescale), and then gently scrub it with a wet sponge of rare water, and you will find that the shiny side of the inside of the kettle can be exposed again.

Vinegar boiling method: first connect the kettle to two-thirds of the kettle, and then add one-third of the vinegar. Then bring the water to a boil and let it boil for 7-8 minutes.

After that, pour out only half of the water and let it cool naturally, and when it cools, scrub the inside of the kettle with a sponge or rag. If the scale is very thick, then use this method, leave it overnight under natural conditions, and wait until the next day to scrub it.

Fruit Cleansing: This method is a bit wasteful, but very original. First of all, we can cut the lemon into small slices or squeeze the orange juice, pour it into the kettle, then add water to two-thirds of the kettle, and bring the water to a boil.

After the water boils, unplug the kettle and stand still for about 1 hour; Then gently rub the inside of the kettle with your hands to pour out the water, and after filling the kettle and boiling it for about 15 minutes, pour out the limescale and it will be gone.

1.Add white vinegar and water to the kettle and heat it, pour it out after a few minutes;

2.Add lemon and water to a pot, heat for 5 minutes and pour out;

In this way, the limescale is removed.

The main components of scale are calcium carbonate, magnesium hydroxide, magnesium carbonate, calcium sulfate, magnesium sulfate, calcium chloride, magnesium chloride, etc

Tricks for scale removal: lemon scale, vinegar scale, tea scale.

1. Lemon limescale

Lemon is the most common fruit in daily life, we can take a lemon and chop it, pour about one-third of the water into the kettle, put the chopped lemon into the kettle and boil it with water, when the lemon is soaked in water for a period of time, pour the water away. At this time, we will find that the limescale in the kettle has been removed, and there is a smell of lemon in the kettle.

2. Vinegar to remove scale

Vinegar is an indispensable condiment in every household. In addition to seasoning, it has many wonderful effects in life. The main component of limescale is the insoluble calcium and magnesium compound of Bizhou.

If there is limescale in the thermos, you can soak vinegar to remove it. The principle of vinegar water removal is that acetic acid can react with insoluble calcium, magnesium salts and alkali in scale to generate soluble acetate, so as to achieve the purpose of removing scale.

3. Tea to remove scale

Pour the tea residue and hot water into the electric kettle, shake it a few times, and leave it for half an hour, and the scale will naturally fall off. The principle is to use theophylline to remove scale.

The principle of scale generation

At high temperatures, the carbonate in the water will combine with calcium and magnesium ions to generate insoluble calcium carbonate, magnesium carbonate, etc., and calcium carbonate, magnesium carbonate and other substances are precipitated from the water and adhered to the container, which becomes scale.

Scale, also known as "water rust" and "water alkali", is a white lump or powder substance that is gradually formed by the mineral contained in hard water after boiling in the container. The main components of scale are calcium carbonate, magnesium hydroxide, magnesium carbonate, calcium sulfate, magnesium sulfate, calcium chloride, magnesium chloride, etc., and the thermal conductivity is very poor.

The scale is formed on the heating surface of the boiler, which will greatly deteriorate the heat transfer effect, and it is easy to burn out the metal materials due to local overheating, and even burst pipe accidents.

Method 1: Place the container with limescale. Pour in the vinegar, pick up the container and shake it, let the vinegar soak in the places with scale, shake it a few more times, and leave the container for about 20 minutes.

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 and submerge the limescale area. Soak for about half an hour, the longer the time, the better the effect. After soaking, you can notice that the limescale at the bottom of the container is almost all off.

Wash the container.

The main ingredient of edible vinegar is acetic acid, and the main components of scale are calcium carbonate and magnesium carbonate. When edible vinegar and limescale meet, calcium acetate and carbonic acid are produced. Carbonic acid can be broken down into carbon dioxide and water, and the calcium acetate formed can also be soluble in water.

Therefore, it can remove limescale, and it is recommended to use strong vinegar for better results. The reason for soaking in warm water and vinegar is that the reaction is faster and the effect is better.

02Method 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 it for about 10 minutes without moving.

If the container cannot be heated, it can be poured in and start soaking for 20 minutes. The higher the temperature, the better the dissolution.

The main component of lemon is citric acid, which is a weak acid. After heating, the weak acid reacts with the scale, causing the scale to fall off. The more lemons, the higher the acidity.

The better. The citric acid detergent products sold in the market are extracted from lemons. Because of the high purity of the extraction, the effect is good.

03 Method 3: Remove limescale from the egg shell, and after eating the egg, the egg shell can be put away. Place egg shells in a container with limescale.

Add two-thirds of the 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 depending on the size of the container.

04 Method 4: Starch descale. For potatoes, potatoes and other foods containing starch, put potato skins and sweet potato skins into a container with scale, pour the container clearly, and leave it for about half an hour.

Because starch has a sticking effect, this method is suitable for scale, and thinner scale containers cannot be effective against very hard scale.

Skillfully remove limescale by using baking soda to easily remove pesky limescale.

Method steps: 1. Rinse the inside with clean water first to remove the excess scale residue.

2. Take half a spoon of baking soda and mix it with water to make a paste.

3. Then dip some baking soda in a clean, oil-free cloth.

4. Then cover the limescale and wipe it back and forth.

5. Wash the scale with clean water again to remove it, and it will be as bright as new.

Notes:1. Baking soda can be mixed into a paste, do not add too much water, so that it is easy to dip.

2. Use a clean cloth to wipe to avoid other dirt from staining the kettle again and avoiding impurity particles from scratching the inner wall of the kettle.

Here's how to get rid of limescale quickly:

White vinegar.

When we use white vinegar to remove limescale, we only need to mix some in the water and then boil it in the usual way, so that the scale will slowly dissolve and fall off in it. White vinegar is a common condiment in the home, but it is not only used for seasoning. Because white vinegar is acidic, it is naturally corrosive, we use it to clean scale can get good results, in addition to white vinegar also has the function of sterilization and disinfection, which can ensure the health of boiling water.

2. Baking soda.

Since we talk about white vinegar, we can't fail to mention baking soda, baking soda is a good thing to clean at home, because it is a strong alkaline substance, so it can react with the scale in the kettle when it is used, and then it can play a cleaning role. The method of using baking soda to remove scale is similar to white vinegar, that is, to dissolve the baking soda in water, and then put it in an electric kettle to boil, and the simple effect is very good.

3. Potatoes. The above two cleaning methods work very well for electric kettles with thick scale, but if the kettle at home has thin scale, we can use the potato cleaning method. Potatoes are known to contain sufficient starch inside, which can effectively remove the limescale when cleaning. We cut the potatoes into thin slices, then put them in an electric kettle and add water to boil, so that the starch in the potatoes will slowly react with the limescale and play a cleaning role.

4. Descaler.

We can go to the market and buy the previous generation of descalers, but be sure to pick a brand of descaler. This is how you can be safer. But even after this descaling, you must remember to rinse several times, and remember that the first two pots of water from the kettle should not be drunk directly, because after all, the descaler is composed of chemical components.

There are several common methods for rapid scale removal:1. Baking soda removal method: add water to boil or soak for 10 minutes.

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

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

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

Scale is mainly formed by the precipitation of salts such as calcium and magnesium contained in boiler feed water after being heated and sticking to the metal surface. The thermal conductivity of scale is very small, about 2 5 of ordinary steel, and the scale is formed on the heating surface of the boiler, which will greatly deteriorate the heat transfer effect and affect the efficiency of the boiler; It is easy to burn out the metal material due to local overheating, and even burst the pipe;

It will aggravate the electrochemical corrosion, cause the scale corrosion of the boiler, and accelerate the damage of the heating surface. After the formation of scale, it should be removed by mechanical or chemical methods in time. The effective way to prevent or slow down the formation of scale is to strictly control the quality of the feed water and take appropriate measures such as boiler water treatment and boiler blowdown.
