How to clean the ventilation? – independently in the apartment and car

Air conditioning, a device that allows you to create an oasis in the middle of a sultry desert, cooling any room to any temperature. You all know very well what this device is. Most of you, dear readers of AutoPulsar, have an air conditioner in your home, office or car, but not every one of you knows how to properly care for this miracle of technology so that it continues to work without causing us harm.

What kind of harm are we talking about - does anyone think to themselves? I will answer, in addition to the common cold, which is most often observed in those who do not know how to use air conditioning, devices of this type can cause many “sores,” mainly related to the respiratory system. Due to the constant temperature difference and condensation that occurs on the working surfaces of the air conditioner, harmful pathogenic bacteria collect on them. Progress does not stand still and modern “condos” already have so-called antibacterial surfaces that prevent the appearance of various types of bacteria. However, practice shows that in fact all this know-how is nothing more than a marketing ploy...

Therefore, in order not to catch something bad from your air conditioning device, it is necessary to carry out preventive cleaning of the air conditioner, that is, in other words, disinfect the car air conditioner .

Why do you need to clean your car air conditioner?

The car air conditioner requires periodic attention and maintenance. Its timely cleaning eliminates the occurrence of unexpected problems and unforeseen expenses, as well as health problems. The fact is that inside the device an ideal environment is formed for the development and reproduction of all kinds of bacteria. During operation of the air conditioner, moisture appears inside, which mixes with dust and dirt that gets inside along with the air. This indicates that cleaning the air conditioner should not be neglected. In addition to the listed nuances, due to the accumulation of contaminants, the performance of the unit deteriorates, which makes it difficult to maintain the required temperature on a hot day, and the appearance of an unpleasant odor in the cabin will be the last symptom indicating a problem with the device.

Conditioner treatment frequency

The most accurate information on cleaning the air conditioner is provided in the owner's manual for your car. If the frequency cannot be determined for some reason, then following the recommendations of specialists, preventive measures should be carried out 1-2 times a year. If you or your family suffers from allergies, then antibacterial treatment should be carried out more often. At the same time, it is necessary to take into account how often the car is driven and the air conditioning is used, what is the climate in your region, and the roads on which you have to travel. Basically, cleaning of a car air conditioner is carried out in the spring before the start of its operation, or in the fall - after its completion. However, no one prohibits cleaning at any time.

Signs that require disinfection

There are several signs that indicate that your device needs to be serviced:

The appearance of extraneous sounds. Their character can be different: crackling, noise, whistling.
Unpleasant smell. It may always be present in the cabin, but when the air conditioning is activated it will intensify.
Appearance of moisture. If it was noticed that when the air conditioner was turned on, moisture began to appear from the air duct, this indicates the need for immediate cleaning of the unit.

Consequences of bacterial contamination of the air conditioner

An unpleasant smell is not so bad. It appears due to moisture (condensation) accumulated on the evaporator. Fungi, bacteria, and mold form in it, which over time cover the inner surface of the air ducts. Gradually, the level of deposits increases so much that it leads to an unpleasant odor when the air conditioner is activated. However, the nuance is not only in the smell, but also in the fact that bacteria pose a danger to the human body.

In addition, road dirt getting between two radiators (cooling and air conditioning systems) leads to disruption of the compressor, which can cause its premature failure. Due to dirt, corrosion appears on the aluminum elements of the air conditioner, resulting in freon leakage.

How to ensure the functionality of air passages in the bathroom

Don't forget about personal safety

Ineffective air exchange in the room is indicated by the appearance of a veil of steam on the mirror surface and the deposition of liquid droplets on all internal surfaces. Or there is an unpleasant odor brought into the bathroom from the ventilation with reverse air flow. If the design of the house has a ventilation system, but it does not work, you need to know how to clean the ventilation in the bathroom. Please note the following:

If you find a channel heavily clogged with debris, it will be difficult to deal with it on your own, so it is better to turn to specialists.
If during the repair the ventilation grilles were masked with wall or ceiling panels covering them, direct access to them should be provided and the panels should be dismantled.
The fan or grille is cleaned. To do this, accumulated dirt is removed from the grate using a spatula or scraper from the chimney side. Fine dust and debris are removed with a vacuum cleaner.
Once in place, the grille is tightly fixed.
The draft in the bathroom is checked. If the result is unsatisfactory, you should try to check the operation of the shaft on the top floor of the apartment using the riser. If it works there, then the reason lies in the gap in the mine - a blocked air duct. In this case, you cannot do without the employees of the service company.

Timely and correct cleaning of the ventilation in the apartment ensures regular circulation of air flow. When installing fans in the ducts, the frequency of removing debris and dust may decrease, but these preventive maintenance operations cannot be canceled in general.

Cleaning your car air conditioner at home

Cleaning the air conditioner involves disinfecting it with special means. It is worth dwelling in more detail on how to use them and what processing methods exist.

Types and sequence of system cleaning

The car air conditioner can be cleaned in one of the following ways:

In the first case, aerosols and foam are used. It is worth considering that with aerosol products you can only disinfect the air conditioning system, but with foam you can also clean it. The mechanical method is resorted to if chemical agents do not give the desired result and an unpleasant odor remains in the cabin. The procedure is difficult because you have to remove the evaporator in the heater block. For chemical treatment of the device in question, you can use products from the following manufacturers:

Chemical method

After choosing a foam or aerosol, you can begin cleaning the air conditioner. Basically, all products are equipped with a tube. Aerosol treatment is performed as follows:

Let's start the engine.
Turn on the air conditioner and select the recirculation mode to maximum.

If you have to use foam products, the process consists of the following steps:

We remove the cabin filter.

Available means

Depending on the disinfectant chosen, you will have to pay about 150–1000 rubles. per can. Inexpensive cleaners can not only be ineffective, but also fill the interior with a not very pleasant odor that is difficult to remove. However, for effective antibacterial treatment it is not necessary to buy expensive products: you can also use improvised ones. To help deal with the nasty smell in the cabin:

Chloramine B;
Lysoformin 3000;
Chlorhexidine.

The essence of the treatment is to prepare a working solution from a powdered substance, for example, Chloramine B, which is diluted with water (1 tablespoon per 1 liter of water).

The resulting liquid is poured into a suitable container with a sprayer. During treatment with the listed means, all doors in the car should be open. The disinfection process is similar to using foam.

If the above methods fail to remove the unpleasant odor from the interior, the air conditioner must be cleaned mechanically.

Mechanical method

When performing mechanical antibacterial treatment of the air conditioning unit, tools will be required to dismantle the dashboard. It will also not be superfluous to replace freon, seals and pipes. The cleaning process is performed in the following sequence:

To gain access to the evaporator, remove the dashboard.

Despite the complexity of the process, the mechanical method is more effective.

Replacing the cabin filter

The main purpose of the cabin filter is to clean the air entering the vehicle. The correct operation of the heater, air conditioner, and ventilation system directly depends on the condition of this element. The need to replace the filter occurs when the windows fog up, an unpleasant odor appears, and the performance of the stove and air conditioner deteriorates.

It is recommended to change the filter element every 10–25 thousand km. mileage, depending on the operating conditions of the vehicle.

Most often, the filter is located near the evaporator. The element in question is made from corrugated paper with cellulose or synthetic fibers, often impregnated with carbon and shaped like a rectangle. To replace the cabin filter on a specific car, you need to read the owner's manual. The process itself consists of dismantling the used product and replacing it with a new one.

Cleaning air conditioning system elements

The cabin climate system includes such basic elements as an evaporator, a radiator, a cabin filter and air ducts. Let's look at cleaning each of them.

Cleaning the radiator and air ducts

First of all, the air ducts and radiator of the system in question are cleaned, removing dust and dirt from them. To do this, an air compressor is used to supply compressed air to the system elements. The procedure consists of two stages:

Using a jet of compressed air or using special means, remove dirt from the radiator. It is usually located near the radiator of the cooling system in the engine compartment.

After completing the described steps, you can begin to disinfect the evaporator of the car air conditioner.

Cleaning the evaporator

A large number of different bacteria settle on the evaporator, causing an unpleasant odor. Therefore, by cleaning a car air conditioner, many mean the evaporator, the treatment of which was discussed above.

Independent work on cleaning the ventilation duct

Special brush for cleaning ventilation

If the hose that removes exhaust air from the apartment to the central shaft is clogged, you need to know how to clean the ventilation in the apartment yourself. Work order:

Clear the space under the ventilation grille from furniture, flowerpots, and other interior items that interfere with cleaning.
Cover the floor covering with protective film and newspapers to prevent dust, dirt, and debris from entering from the channel.
The wall under the grille is covered with oilcloth and old wallpaper attached to it with masking tape.
The work is carried out on a serviceable and stable stepladder, pushed up against the wall.
The grille masking the ventilation hole is removed.
If there is an exhaust fan in the niche instead of a grille, it must also be dismantled by first unscrewing the screws securing the housing.
The grille and fan blades are washed well with a detergent that breaks down fatty deposits. Wipe dry.
If the condition is unsatisfactory or there is a lot of physical wear, the grille is replaced with a new one.
Work is carried out wearing mittens or gloves.
For mechanical cleaning, a thick (diameter 10-12 mm) cable is used. A ruff or a “doll” wound from rags is attached to the end. Using rotational and translational movements, moving up the channel as far as possible, clean it from dirt, grease, and cobwebs.
To avoid injuring your hands from possible debris inside (nails, remains of birds and rodents, glass), all contents at the bottom of the channel are removed using a construction spatula. You need to try to stick your hand as deep as possible.
Dirt stuck to the walls on the outside of the hole is also removed with a rubber, plastic or wooden spatula.
Small debris and dust that cannot be manually cleaned are removed from the cavity with a vacuum cleaner.
The grate is put in place.
Control check of traction with the window open.
If it remains unchanged, you need to contact specialists at the management company for more detailed cleaning.

Not only horizontal outlets, but also vertical ventilation structures are brought into proper shape. But the apartment owner should not do this. Only specialists should clean ventilation ducts in an apartment building.

Attention! Solving the problem of clogging a ventilation shaft in an apartment building on your own by burning out cobwebs and debris or using chemical compounds is prohibited.

How to prevent odor and delay repeated disinfection

The procedure for disinfecting and cleaning a car air conditioner is clear, but in order to resort to it as little as possible, you should follow some recommendations:

change the cabin filter promptly;
avoid the formation of dampness.

If the first tip does not raise any questions, then in the second case it is better to dry the air conditioning system naturally, and not with the help of a heater. In this case, the cooling should be turned off at least 5 minutes before the arrival point, leaving only the fan running to dry the system. Thus, condensation will form in a minimum amount, which will reduce the likelihood of an unpleasant odor.

Periodic maintenance of your car's air conditioner can minimize the occurrence of problems with the system and the need for expensive repairs. After reading the step-by-step instructions, every car enthusiast will be able to disinfect the device. If simple cleaning methods do not give the desired result, the air conditioning system needs more thorough treatment.

Causes of malfunctions

As soon as you have discovered that the stove on your Renault Megan Scenic 2 is not heating well, you should work closely on resolving this issue in the very near future. Don't wait until the heater fails completely.

Depending on how the Renault Scenic heater equipment behaves, you can potentially identify possible malfunctions.

Situation No1. The heater functions, turns on, but does not heat

If the stove behaves this way, there are several possible reasons:

The thermostat has failed. The device is jammed, so the cooling liquid circulates only in a large circle, without passing through the stove radiator. As a result, the engine may overheat, but cold air still flows into the cabin from the deflectors. The problem can be solved by replacing the thermostat;
The radiator is clogged. Usually it becomes clogged during long-term use, due to accumulated debris, due to improper mixing of antifreeze, or due to the banal use of water instead of coolant. The use of sealants that supposedly eliminate leaks in radiators can also lead to clogging. There are usually two ways out of the situation. The first option involves flushing the stove radiator, and the second, replacing it. You need to act based on the specific situation. Some radiators cannot be flushed, so there is no alternative to replacement;
There is not enough coolant in the expansion tank. The situation is extremely banal and simple to solve, but no less common among Renault Scenic 2 owners. Check the antifreeze level, top up if necessary. It is possible that a leak has formed in the system, so the liquid drains quickly. You will have to find the source of the leak and eliminate it. Also, be sure to check the functionality of the valve cover of the expansion tank and its ability to bleed off excess pressure and pump it in as needed;
Airing. Depressurization of the cooling system and wear of the cylinder block gasket can lead to the formation of a suction effect. Excess air enters the system, which contributes to the creation of an air lock. But even more often, a traffic jam occurs due to improper replacement of antifreeze;
Damper failure. This option cannot be ruled out. Although the dampers break quite rarely in the case of the Renault Scenic 2, it is better to check them than to disassemble half of the interior to get to the heater radiator;
Clogged cabin filter. Another fairly common reason for poor ventilation of the heater in the second generation Renault Scenic. Many car owners forget to change this consumable, although according to recommendations this should be done every 5-10 thousand kilometers, depending on operating conditions.

Situation No2. Heater fan does not turn on

If you are trying to turn on the stove on the control unit, but there is no reaction, the reasons may be the following:

The electric motor itself has failed. Removing it is not very difficult, but this procedure will take some time. The motor can potentially be repaired by lubricating the bearing and replacing worn brushes. If the electric fan does not work, it will have to be replaced. But first make sure that the problem is not in the contacts, and that the fuse is not blown. Otherwise, instead of 5 minutes and 30 rubles, you will spend the whole day and several thousand;
Damage to the control unit. It rarely breaks down, although sometimes this happens on Renault Scenic 2 cars of the French automaker. The main reason is the failure of the resistor. You can change it yourself. It's not that difficult. Sometimes the device can even be restored. The main thing here is to carefully remove the block of additional resistance (resistor) and install it in the reverse order;
Contacts are broken or wiring is broken. Because of this, no power is supplied to the equipment. Accordingly, the stove cannot turn on. You will have to check the condition of the contacts, change the wiring if there is damage, work a little with a blowtorch and restore all contacts;
The resistor or additional resistance has broken. This type of breakdown has a characteristic feature. It manifests itself in the fact that the stove does not turn on at the first 3 speeds, but at the last, maximum, it works. It's all about directly connecting the fan at the latest speed. And to reduce the speed of rotation of the blades, a block of additional resistance is used. If this resistor breaks, a number of speeds will not function.

Based on your current situation, you can begin further work.

How to eliminate odor

You can eliminate the smell from the air conditioner evaporator by either dismantling and washing the evaporator radiator, or cleaning it of bacteria without removing it from its original place. The first cleaning method allows you to clean the evaporator radiator better, but is more labor-intensive, and after assembly, the air conditioner will need to be refilled. You can clean your car air conditioner with your own hands, without disassembling it, using an aerosol or liquid as follows:

It is recommended that the air jet is not directed forward and that passengers are not exposed to large air jets. The nozzles should be vertical so that the cold air mixes slowly with the hot air. Dangers you create when using air conditioning.

The air conditioning in your car can be just as dangerous to your health as the air conditioning in your room. Legionnaires' disease or allergies can also affect drivers, not just housewives. Regularly changing the filter becomes a necessity, especially after the discovery of Legionella, the bacterium responsible for Legionnaires' disease, grows very well in fluids used for cooling or even in windshield washer fluid.

Dry the air conditioner radiator. To do this, warm up the engine and turn on the interior heater in the car for a few minutes.
Turn off the heater.
Remove the cabin filter for the car's fresh air ventilation.
Open the air intake damper from the street.
Open all the doors in the car wide open.
Cover the outlets of the air ducts into the passenger compartment with a loose cloth so that the cleaning agent drips less into the interior of the car.
Turn on the air conditioner and spray cleaning agent into the hole for the cabin filter.

Filters must be cleaned thoroughly and often. Filters should be changed within the time recommended by the manufacturer. That is, even if you're currently cringing when you hear your car's pollen filter. It's really effective, especially when you go with your little ones. From time to time, it gives your car the "luxury" of a complete interior cleaning, including sucking up dust in coats and banquets. For the simple reason that when using a recirculation system, you risk dispersing all the dust collected in the car into the air.

Start your air conditioning system in winter. Air conditioning can and even should be used in winter. Since the freon route consists of several elements connected to each other by some pipes. They have some oranges, some gaskets that don't lubricate for a long time, risk cracking and allow the freon to escape quickly. That's why it's good to drive in air conditioning in the winter, even if we don't have heat, even if we don't have paired glass, it's just the freon sneaking through the circuit and because the oil with which it mixes is lubricated and always wear pads.

Reasons for cleaning your car air conditioner

The main cause of unpleasant odors from the air conditioner lies in the moisture that accumulates on the evaporator. Where does it come from? When the car engine and the air conditioner itself are turned off, warm air enters the cooled air ducts from the street. With such contact, condensation of moisture in the air occurs.

Condensed moisture is not distillate. It inevitably contains various fungi, mold and bacteria, which, together with moisture, settle on the surface of the air conditioning system ducts. Over time, the level of such deposits increases, which, in fact, leads to the appearance of unpleasant odors when the car air conditioner is turned on.

It must be remembered that the mentioned bacteria are not only a source of unpleasant odors, but they themselves are dangerous to the human body. Therefore, if a musty smell appears when starting the car air conditioner, it is necessary to perform antibacterial cleaning as soon as possible.

When to clean your car air conditioner

There are three main signs, if at least one of them appears, it is necessary to clean the air conditioner in the car. So, these include:

The appearance of extraneous noise during operation of the car air conditioner. This may be whistling, crackling, buzzing. This “sound” clearly indicates a problem with the system. And the first thing you need to do is clean the air conditioner. If extraneous sounds persist after this, then additional diagnostic and repair measures must be taken.
The appearance of an unpleasant odor. The reason for its appearance was stated above.
Appearance of moisture. Condensation usually appears from the air duct. During normal operation of the air conditioner, moisture is removed through a special tube designed for this purpose. If moisture has entered through the air duct, it means that the air conditioner definitely needs to be cleaned because the drain tube is clogged.

Do-it-yourself car air conditioner cleaning

Before you clean the car air conditioner yourself, you need to consider two things - the design of the air conditioner, as well as the means with which you can carry out the appropriate cleaning. The air conditioning system in the car interior consists of the following main components: evaporator, radiator, air filter, air ducts.

These elements of the car air conditioner are cleaned using special cleaners. But if this is done at home, then sometimes a cheaper alternative remedy is used, which can be bought simply at the pharmacy (details are discussed below). Let's look at how to clean the radiator, evaporator and antibacterial cleaning of air ducts separately.

How to clean an air conditioner radiator

The first step is to get rid of dust and dirt in the air conditioning system ducts, as well as directly in the radiator. This can be done using an air compressor, directing compressed air into the system. For example, to do this, use a car tire pump. The work is carried out in two stages:

Using a jet of compressed air, you need to get rid of dust and dirt on the car air conditioning radiator (on the condenser). Located in close proximity to the radiator of the engine cooling system in the engine compartment of the car. The main task is to blow off all (or almost all) dirt and dust from its body. If possible, remove dirt with a brush.
Using the same air compressor, you need to blow out the air intake grille, which is located under the windshield. It is from there that the air enters the car interior. Similarly, it is necessary to blow out the deflectors located inside the car. They also accumulate dust over time, which is harmful to the human body in itself, and can also cause an unpleasant odor in the cabin in the long run.

Only after such a procedure can the evaporator of the car air conditioner be disinfected.

How to clean an air conditioner evaporator

It is on the evaporator that most of the bacteria and microorganisms mentioned above, which are sources of unpleasant odors, settle. Therefore, for many, cleaning the evaporator is associated with cleaning the car air conditioner as a whole.

For this purpose, two types of means are used - aerosol and foam. The algorithm for their use differs accordingly. Therefore, before using this or that cleaner, be sure to read the instructions for its use!

Please note that aerosol air conditioner cleaners are divided into two more types - those that require removing the cabin filter, and those with which this procedure does not need to be performed. Therefore, additionally clarify this information in the instructions directly on the aerosol can.

When using an aerosol air conditioner cleaner for disinfection, the sequence of actions will be as follows:

Start the car engine at idle speed.
Turn on the car air conditioner and install internal air recirculation in the car interior (without access to air flow from outside).
Open all supply and exhaust ventilation openings in the cabin.
Shake the aerosol can thoroughly, place it in front of the front passenger seat and start spraying.
Leave the car and close all windows and doors.
The duration of the procedure is indicated in the instructions for the specific product, but it is about 10 minutes.
After the allotted time has expired, you need to ventilate the interior well (by opening the windows and doors). Airing also takes at least 10 minutes, preferably even longer.

Foam car air conditioner cleaners work on a similar principle, but they must be added directly to the air duct system. Their advantage is that the foam not only disinfects, but also cleans the system of dust and dirt.

The algorithm for using foam cleaners for antibacterial cleaning of a car air conditioner will be as follows:

Treating the evaporator with a foam cleaner

Remove the cabin filter. If the car does not have such a filter, then you need to blow foam into the air conditioning system through the drainage hole.
The amount of foam and operating time of the composition are directly indicated in the instructions on the packaging of the cleaner. Typically this time is 10...20 minutes. However, you need to focus not on time, but on the moment when the foam turns into a liquid mass that flows down.
Start the engine at idle speed and turn on the air conditioning first at minimum temperature and at minimum speed of the drive fan. This is done so that condensation forms on the evaporator, which should subsequently wash away dirt from the evaporator. It is the foam that softens this dirt.
After cleaning, you need to thoroughly check the interior of the car.

It is up to the car owner to decide which cleaner to use - aerosol or foam. Aerosol disinfects better, while foam cleans better from dirt and bacteria.

A few tips for eliminating odor

First, you need to monitor your cabin filters. They must perform their task well. If desired, remove unnecessary debris and dirt from the filter between filter replacements. You should not skimp on the filter, as a cheap one may have gaps through which some of the unpurified air can get in. Such a filter will only cause harm. I think you have received the answer to the question of how to clean the air ducts in a car. There is one more recommendation.

Final Rule

. It is always necessary to dry the evaporator before the vehicle is left idle for a long period of time. To do this, you need to turn off the air conditioner in advance, for example 6 minutes. The fan does not have to be turned off. Since hot air will help the evaporator dry, thereby preventing bacteria from multiplying in a dry environment.

A car air conditioner cleaner is a product that not only restores the effective operation of climate control, but also ensures that its internal elements are cleaned of dust and dirt, in which, in turn, pathogenic bacteria (possibly even fungal infections) multiply, which cause unpleasant odor in the car interior and deterioration in the well-being of passengers.

Therefore, regular use of a car air conditioning cleaner will not only create and maintain a comfortable temperature in the cabin, but will also protect the driver and passengers from inhaling harmful substances. There are both factory-made products for cleaning air conditioners, and compositions that you can make yourself. It must be remembered that the cleaner is usually used in combination with other products intended for cleaning the interior, ventilation elements, and so on. And in order to figure out what cleans better and which cleaner best copes with the task, a rating was created based on the characteristics and results after use by real people.

How to clean the air conditioner in a car yourself at home

Cleaning the car air conditioner yourself video

To clean a car air conditioner, in principle, it is not necessary to buy expensive special products. There are two alternatives using medications. However, both of them allow only disinfection. Therefore, if you want to get rid of the problem for a long time, it is better to purchase products that will allow you to clean the evaporator from dirt.

How to clean an air conditioner evaporator with Lysol

In addition to using products specially designed for cleaning the air conditioner, many car enthusiasts (and not only them) use a product called “Lysol” for these purposes. It is also a “Cresol” solution based on soap and oil. The active ingredient is phenol.

It is used for professional disinfection (they produce disinfectants for hospital operating rooms, surgical instruments, air conditioners). Also often used in restaurants to remove unpleasant odors from grills. Therefore, there is no need to doubt its effectiveness.

For subsequent antibacterial cleaning of the car air conditioner evaporator, it is necessary to obtain Lysol in concentrated or diluted form. This thing is quite expensive, so it is advisable to use medical solutions. They even come with flavors. Kon is diluted in a ratio of 1:100, and surgical - 1:20. To work, you will need approximately 300...400 grams of the finished solution. Next, the procedure will be performed according to the following algorithm:

Fill a hand spray bottle with the resulting solution.
Open the windows in the car.
Start the car engine and turn on the air conditioner at full power, including turning the fan on as high as possible. In the cabin, direct the nozzles down towards the floor.
Get out of the car and use the mentioned hand sprayer to spray the solution into the air intakes near the windshield. You need to spray with cloud/fog. The procedure lasts two to three minutes.
Turn off the engine and wait about 10 minutes.
Restart the engine while the air conditioning and fan continue to operate at full power.
Turn on internal air recirculation on the air conditioner (prevent air from entering from the external air intake).
Spray the mixture from a bottle under the front passenger's feet, under the glove box. This is where the air intake in recirculation mode is located. The procedure lasts the same two to three minutes.
Turn off the ignition and wait about 10 minutes.

In most cases, such cleaning is enough to reliably get rid of the unpleasant odor from the air conditioner. In extreme cases, you can repeat the procedure again in about a day. Ideally, in addition to the described algorithm, it is also advisable to dismantle the interior elements in order to get to the evaporator and apply the Lysol solution directly to it.

Cleaning the air conditioner with chlorhexidine

Chlorhexidine has the same properties as Lysol described above. This drug is also used for disinfection in medical institutions. To clean your car air conditioner with chlorhexidine, you can buy a ready-made 0.05% solution of this product at the pharmacy. To increase its effectiveness, dilute with alcohol 1:1.

Cleaning the air conditioner with chlorhexidine is carried out according to the algorithm described above (sprayed from a sprayer onto the evaporator while the system is running). Please note that it is best to perform treatment with chlorhexidine at an ambient temperature of more than +20°C.

Instead of chlorhexidine solution, you can use other similar products, for example, Lysomorphine 3000. This is a Russian-made drug. Used for disinfection for medical purposes, including especially dangerous infections. To obtain a ready-made solution for cleaning the air conditioner, you need to dilute 50 ml of the product in one liter of water.

Another remedy is Chloramine B. Sold in the form of a white powder. To obtain the finished solution, you need to dilute one tablespoon of powder in one liter of water. Use according to the above algorithm. The main thing is to apply the product to the evaporator!

Renault Grand Scenic 1.5 dci k9k732 › Logbook › Cleaning the air conditioner evaporator

Every spring, when the weather warms up, I clean the air conditioner evaporator. I won’t describe in detail why this needs to be done, and how bacteria appear on the evaporator, which “stinks” and harms our health. There are a lot of articles about this on the Internet. Plus, the manufacturer himself recommends regular cleaning.

For me, the signal to clean is usually an unpleasant smell when the air conditioner is turned off and sudden snot in May
