Scale and chemistry for its removal
The basis of scale in household washing machines (SM) is insoluble carbonates of magnesium and calcium (CaCO3 and MgCO3)settling on the details. They determine the water hardness level, and their concentration affects not only the scale formation process, but also the chemical effectiveness of the detergent.
In accessible places, salt deposits can be torn off mechanically, but getting to scale on a heating heater is quite problematic.
Therefore, to remove it in hard-to-reach places, a chemical method using citric acid is used. She dissolves CaCO3 and MgCO3, and does not corrode metal surfaces.
The chemical reaction is as follows:
2C6N8ABOUT7 + 3СаСО3 = Ca3(WITH6N5ABOUT7)2 + 3CO2 + 3H2ABOUT.
During the reaction, calcium citrate is formed in the SM (Ca3(WITH6H5O7)2), which dissolves well in water and is removed with it when draining. It is safe for humans and is even available in tablets to replenish calcium reserves in the body.
Theoretically, to clean a washing machine from 100 grams of scale, 125 grams of citric acid would be required. This chemical fact must be remembered when evaluating the effectiveness of the cleaning performed.
Causes and consequences of scale formation
The scale formed in the washer is a fait accompli that requires a response. But one cannot ignore the reasons for its appearance, which can repeat the process of salt deposition on the details.
Scale formation is promoted by:
- carbonates, cations of calcium, magnesium dissolved in water;
- high washing temperature (over 60 ° C);
- the use of phosphate-free powders.
The effect of high temperatures lies in the fact that with strong heating on the metal surface of the heating elements steam bubbles begin to form - the result of local boiling of water.
At the micro level, this leads to its separation into a pure fraction H2Opassing into the surrounding liquid, and insoluble carbonates deposited on the metal. The higher the washing temperature, the more limescale is bound in one cycle.
Besfosfatny powders favorably affect ecosystems of reservoirs into which the sewerage merges, but they bring only problems to people.
Phosphates reduce the overall hardness of water and inhibit the formation of insoluble carbonates, so they are used in special products for the internal cleaning of washing machines.
The absence of phosphates in washing powders leads to an acceleration of salt deposition on the SM parts.
The formation of scale is fraught with the following consequences:
- Overheating of the heater due to poor heat transfer to the surrounding water through scale.
- A layer of salts isolates metal and rubber parts from air, which helps retain moisture in them, moldrust and reduce strength.
In general, scum is not good enough, so you should remove it with citric acid or specialized scum for washing. The features of this method should know the maximum information.
Pros and Cons of Citric Acid Cleansing
The properties of citric acid are due to its chemical structure. This substance was not specifically invented for cleaning washing machines, therefore its effect on the details of the technique has both positive and negative sides.
The positive aspects of the method
Without scaling in the SM, one can expect, at a minimum, burnout and the need replacement of TEN. Therefore, pulling with a cleaning procedure is not worth it. The method of removing deposits should allow everyone without experience to carry out the procedure.
The use of citric acid to eliminate accumulated insoluble salts meets this requirement due to several advantages:
- Availability and low cost. The right amount of citric acid can be bought at any store for several tens of rubles.
- Simplicity. Even an unprepared person can carry out the cleaning procedure.
- Efficiency. 100 g of citric acid will dissolve up to 80 g of scale.
- Safety. Both citric acid and calcium citrate formed after dissolving scale are harmless to health.
These positive aspects of LC make it the drug of choice in the fight against scale. It makes no sense to buy expensive special means for cleaning SM, if they provide a similar effect.
Confirmation of the effectiveness of removal of the accumulation of citric acid is demonstrated in the video:
The negative effects of citric acid
There are legends about the negative effect of citric acid on internal parts when cleaning the washing machine. Numerous arguments are presented against this method, but few provide evidence.
The theoretical claims of people to clean SM with citric acid are:
- The formation of salts that remain in the washing machine and can clog the drain.
- Acid corrodes the metal components of the heater.
- Rubber seals soften and may crack.
- After cleaning things have a specific smell.
A 1% citric acid solution is used to remove scale in the SM.
For comparison, a 10% solution of aggressive hydrochloric acid is used to clean water boilers from deposits. And even multiple processing with such a powerful tool does not affect the operation of the equipment. And rubber is generally resistant to short-term exposure to weak acids.
A problem will arise if crystals or a solution of citric acid remain in the pocket of the rubber cuff that seals the door. In other cases, the negative effect of citric acid on the inside of the washing machine is a myth.
The salts formed during the cleaning of the scale along with the residues of LA are completely removed by the next two or three rinses, leaving no smell or sediment.
Are all the cons of citric acid turned out to be far-fetched? No, descaling has another drawback, but it is common to all cleaning products.
Insoluble salts can accumulate in places where water leaks, temporarily tightening the hole and removing the problem. After cleaning the washing machine, the leak may appear again. The described problem is not initiated by citric acid or other means, but the possibility of its occurrence should be remembered.

Instructions for cleaning the machine "lemon"
Citric acid cleans not only the internal parts of the CM, but also the box for falling asleep powder, the door and its rubber gasket.
To do this, you will need:
- 100 g of citric acid;
- water absorbent rag.
The following step-by-step instructions for cleaning the washing machine with citric acid are guaranteed to help get rid of internal deposits of salts, without harming the details of the equipment.
Step # 1: preparing for cleaning
You should first check the drum again and remove things from it, if any. Then measure out 100 g of citric acid for a washing machine with a load of 6 kg. If the technique involves a different maximum amount of laundry, then the amount of reagent should be adjusted in the appropriate direction.
You can use a lemon in 2 types:
- diluted in water.
Dissolved acid is preferred because crystals are guaranteed to not get stuck anywhere. 100 grams of lemons are bred in half a liter of warm water. LK in dissolved form is not suitable for cleaning washing machines, which at the beginning of work pump out the remaining water under the drum.
Step # 2: loading acid and turning on the washing machine
Crystalline powder is loaded into the receiver for washing powder, and the dissolved lemon can immediately be poured onto the drum before closing the door.
The maximum long-term washing mode with a water temperature of 90-95 ° C is selected and turned on. It should have a minimum of 3 rinses.
Step # 3: removing crystalline acid residues
After the final set of water in the machine, open the compartment for loading the powder and rub the remaining lemon along its walls. If she is not there, then you can borrow a little reagent in the kitchen.
After 30-60 minutes, it is necessary to wipe the compartment with a damp cloth, removing the plaque there. The main thing is to have time to remove the acid before starting the rinse regimen.
Step # 4: inspecting the washing machine
After washing, open the door and allow the interior to dry. Separately, you need to wipe the accumulated water in the pocket of the rubber cuff.
Additionally, you can remove the bottom panel of the machine and clean the drain filterin which breakaway particles of limescale may be stuck.
The door SM and rubber seal must be wiped with a cloth soaked in 1% citric acid solution. The remaining plaque on them should be easily removed. This completes the descaling process. It is important to wipe the rubber seal well so that you don’t have to replace sealing cuff.
Product Care Tips
Professionals recommend using special equipment regularly to prevent the appearance of scale. This advice can be ignored if every 4-6 months washing machine cleaning “Lemon”.
The frequency of the procedure depends on the hardness of the water in the region and the average temperature of the wash. The higher they are, the more often you need to clean the equipment.
Inside the machine, citric acid is in contact only with the heater and the working space of metal, plastic and rubber. She and her couples do not get on the engine, the electronic board and other critical elements of technology, so you should not be afraid of the regular use of LC.
Although the process of cleaning SM with citric acid is quite simple, it’s better to prevent the formation of scale than to remove it later.
The suggested tips will help reduce the deposits of insoluble salts on the internal parts of the machine and reduce the likelihood of its breakdown:
- After washing, keep the drum open until it dries completely.
- Buy powders containing water softening components.
- Pour detergent in the volume recommended for hard water.
- Do not machine shabby, decaying clothes.
- When washing, it is preferable to use modes with a maximum temperature of 40-50 ° C.
- Pull linen from the SM immediately after washing.
When descaling, do not exceed the established concentration of citric acid.This will not enhance the effect, but only lead to excess cash costs.
And we must not forget about the mandatory wiping of the sealing rubber cuff to dryness after the cleaning procedure.
