Car enthusiasts that are particularly often air conditioned, often face the problem of an unpleasant smell of air from the salon ventilation system. So you turn on the fan, and instead of the expected cool breeze, the smell of the garbage bucket is "dumped". This unpleasant smell is especially strong in case of high humidity. There are already two alternatives, or to roast on the heat, or tolerate the smell, covering the nose with your hand. Although no, there is one more. Try to find the source of the smell and eliminate it. It is the question wherever he and on alternatives to get rid of this smell we will deal with this article.
In fact, the smell is the result of rotational processes, the reproduction of microorganisms on the surfaces of the ventilation system of the car. Indeed, the most favorable place for the growth of bacteria and for accumulation of garbage is an air conditioner evaporator. In fact, the evaporator is a radiator that cools the air. The air is dragged through the cabin filter or through the air intakes in the cabin (if recycling is enabled), then passes through the evaporator and is sent to the cabin. The evaporator at the same time, as all radiators have a very developed area and a complex shape, it is this feature that contributes to a large number of dirt and dust on its surface. At a time when air conditioning is turned on, the evaporator has a temperature below the ambient air, respectively, condensate will be formed on it. When we come to the parking lot and turn off the air conditioner, then the evaporator often remains the moisture, which now, together with the mud, heats up to the ambient temperature.
As a result, we have all the factors for breeding bacteria, the occurrence of rotting on the evaporator is water and dirt. So it turns out the smell, which as is not called: the wet rag, the smell of the refrigerator and in a joke, the smell of the old Japanese.
Of course, bacteria accumulates on other elements of the ventilation system, the fungus multiplies, but it is less massive. So, with the source of the smell of going on when the air conditioner is turned on, we figured out, now consider the options to get rid of it.
How to get rid of smell from the car's air conditioner do it yourself?
The answer to this question is simple, but the solution is multifaceted. Of course, from ventilation of the car, it is necessary to remove all the garbage, or at least neutralize bacteria living in secluded corners. In order to clean like the ventilation and get to the evaporator of the air conditioner, in some cases it is necessary to disassemble the instrument panel, and this oh, how not to hunt, and sometimes it is also not easy. An alternative to not to disassemble the instrument panel and not climb in search of malicious bacteria in the debris of your car, the use of gas, foam and liquid antibacterial drugs. Of course, the effectiveness of such treatment is torn, and relapse with an unpleasant smell higher, but the complexity is significantly lower.
Getting rid of the smell of air conditioner using a gas antiseptic
One of the most simple ways to get rid of smell, this is a gas antiseptic.
The sequence of its use is as follows. First of all, we turn on the air recirculation mode in the cabin, turn on the fan to the middle position. We find holes through which the saloon air fence occurs. As a rule, they are located at the foot of the driver and passenger. To detect air flow, you can apply a flame lighter. We base the cylinder in such a way that the emerging stream is headed into the air duct. Next, open the cylinder.
We close the car and leave minutes by 10. The processing was carried out.
If we talk about the pros, then this is the minimum effort. If we talk about minuses, then minimal efficiency.
Such a version of the antiseptic for cleaning the air conditioner resembles a cylinder with mounting foam and tube extension.
Used as follows. We remove the cabin filter and release the maximum volume of foam into the ventilation and air conditioning system.
Next, we start the engine and warm up the cooling system. The foam will still expand somewhat and go further. We are waiting for the foam, after about 10 to 15 minutes. After turning on the heater to work in different modes, in order to dry the foam and pull the antiseptic pairs into the system. The effectiveness of this method is somewhat higher than the previous one. Here foam is used locally and the concentration of the substance is higher, even there is a chance that it comes to the evaporator (if it is under the panel).
Processing with a liquid antiseptic will require you to maximize the penetration of the dislocation of bacteria, as in other times and in the previous cases.
In order to prepare an antiseptic with its own forces you need to have:
- chlorhexidine - 500 ml 0.05%. (Medical preparation is used to handle medical instruments, surgeon's hands, for preventing sexual diseases)
- You can add alcohol to this solution (1 part of the alcohol to 5 parts of chlorhexidine)
- At your request, aromatic fragrance can be added.
Without high-quality education, steam is an antiseptic, the effectiveness of its application will be minimal. To spray the system, it is best to use a spray gun for spraying plants. The mixture is used to flush the air ducts and evaporator.
Couples are absorbed through recycling air intakes with a fan turned on. Next, the processing is carried out through the hole for the installation of the cabin filter, towards the evaporator, also with the operating fan
Of course there are specialized solutions in liquid form for washing air conditioners. (example in the photo below)
Their main feature is a loyal effect on the evaporator materials, they do not react, do not oxidize the metal. If you apply COMET, DOMESTOS or their analogues, then in the future you can easily fear for serviceability, the tightness of your evaporator. Household chemicals can harm the integrity of aluminum parts. That is, if you decide to wash a liquid solution purchased in the store, then take the specialized composition.
And here is the apogee in the methods of cleaning the evaporator and the ventilation system and, as a result, getting rid of the unpleasant smell by 100%. This method will not be replaced if your evaporator is in the depths of the instrument panel. You have to disassemble the ventilation system, cleaning the ribs of the evaporator radiator, plastic cabinet parts with a dust and a rotor fungus.
To clean the aluminum parts, apply the composition of the liquid described in the previous version (not importantly purchased or manufactured by himself). For cleaning plastic can apply household chemicals.
As they would not be simple and at first glance, the methods described above are effective, but you will never remove the reason from the air ducts - the body - the body (dust, insects, seeds, foliage), if they were there, then there will be a "slow motion bomb", Which will show itself again. The photo below shows that it was found in disassembling the ventilation system, which filter did not cope with which volume of garbage he missed the evaporator.
Fungus on the walls of the ventilation system parts.
The fungus sometimes and with direct contact is very difficult to destroy, and remotely do it even more difficult. Disassemble and clean the most effective, but the most time-consuming way for those who want to get rid of the unpleasant smell.
Recommendations of preventing not pleasant smell when you turn on the air conditioner in the car
First of all, follow the cabin filters. Filters must effectively cope with their task. If possible, even in the interval between the replacement of the cabin filter, pull it out and remove the dirt and dust from it. The use of high-quality filters is also associated with the filter efficiency. So sometimes saving, we buy not an original filter. There is nothing terrible in this if the filter is made according to the size of the original. There are cases when the filter has obvious gaps through which an alternative, not purified air flow falls, such a filter is evil, and the savings are doubtful.
The second is a simple rule. Dry the evaporator before you put the car on a long parking lot. For this, prudently need to turn off the air conditioner in advance, 3-5 minutes before arriving at the place of your following. Fan Do not disconnect until the end of the trip. The warm air dries the evaporator, relieves it from moisture, respectively and bacteria will deprive the possibilities comfortably fruit in the womb.
The main reason for the unpleasant smell of the car is considered contaminated evaporator. If he was not washed for a long time, the cause of the smell may be bacteria that are formed on it. After reading the entry, you will learn how to eliminate it yourself at home.
Colonies of bacteria appear in the device of the air conditioner due to the constant circulation of cold and hot air. If, after a long operation, the air conditioner is turned off, the cold air from the street falls on its main part after active work. Such air creates condensate, which is removed by drainage tubes, but its appearance is enough to become a good place to form bacteria.
The cause of the smell is exactly what. Working while driving a car, air conditioning, namely, its main part, evaporator, heats up. After turning off the air conditioner, it enters cold air from the street. Interacting with a heated detail, the air settles as moisture, as a result of which the colonies of bacteria appear on it. The smell from them can be both weak and strong, but always it looks like a smell of a wet cloth, left for several days in a locked point. 
Such condensate from mold and bacteria gives it to know yourself, starting to smell during the next inclusion of the air conditioner, filling the salon unpleasant wet and fine air. The air vents in the process of operation of the device are dried, and there are direct access to neoplasms, which are the cause of the smell.
Elimination by chemistry
Solve the end of the air at best can be correct operation of the cooling device. Turning it off to the stop, you alone give the system to ventilate, and already on the car parking lot your air conditioning will expect the next turn on dry and clean. But this approach does not always solve the problem completely, and his minus is that you are obliged to sacrifice our comfort, without exploiting the possibilities of your car fully.
Another way to get rid of harmful bacteria colonies is on time or periodically disinfection of the cabin, and most importantly - air conditioner with evaporator. Usually, chlorine is used for disinfection of cranes and any other products. But for the car, this method of cleaning is hardly suitable, although the chloric is a very strong reagent, it will have to use it in the respirator or even a gas mask. Agree that in our days there are more practical and convenient methods of disinfection, and use chlorine to clean the airlows of your vehicle is a bit incorrect.
The best option for washing the evaporator is a tool that can advise in any pharmacy or medical institution. Moreover, they use it even for disinfection of medical devices. The tool is called cresol, it does not have a strong third-party, they are cleared tools before surgery, medical gloves, and it kills it a large number of bacteria of different types, including cholera. Crezol is called the main component of the Lizol, which is diluted with soap-oil fluid.
The disinfectant properties of cresol are very strong, and the reason is the valid element phenol. It is the main ingredient of the compositions that are used for the disinfection of cars. Professional cleaning of air conditioners, hotels and educational institutions is carried out by professional means, which can sometimes be expensive. Packaging such a means may be enough for a long time, and for cleaning the air-conditioning machine, it may take quite a bit of such a composition.
Flushing evaporator
The washing of the evaporator is carried out in several stages. These steps should be performed consistently, and as a result, you can get a completely new evaporator and the air conditioning system that will not smell, and will fill the interior with clean fresh air without sweat and bacteria. 
- First you need to buy a cleaning agent, namely Lizol. If it is not, you can find any other composition containing this drug. You can also buy a concentrated liquid based on lysol.
- The composition is divorced in water in accordance with 1 to 100, and 300-400 milliliters funds should be enough.
- Cleaning liquid to pour into a bottle or sprayer. Escape a bottle of sprayer and add a little essential oil - so work will be carried out simply and with the smell that you like.
- Open the windows of the machine and the hatch of the manifestation - to work a constant influx of fresh air from the street is necessary.
- We include ignition, and with it air conditioning and fan. The nozzles of the air lines in the area of \u200b\u200blegs or faces
- A solution is disseminated into the hole of the air intake, it is desirable to do it not with a jet and not large portions. But it should not save, because Lizol should get inside and struggling with bacteria. It is best to create large clouds of small drops of cleaning fluid.
- Disconnecting the engine, allow the solution to perform its task inside the air-conditioning system.
- After some time, we turn on the system again, and we spat out the residues inside the cabin. If all the steps are performed correctly, soon in the cabin will again begin to circulate clean air.
The frequency of using the air conditioner affects the appearance of bacteria directly. Conditions of operation in this issue are playing not a latter role. A dusty country road is much worse displayed in a condition of the capacitor, rather than the urban view of the level asphalt. Well, of course, the cleaning of the capacitor on the service is much lengthens the service life and the correct operation of the air-conditioning system.
Since the unpleasant smell is unable to force anyone, it is best to protect yourself from his appearance. The result of the correct operation of the air conditioner will never bring trouble to the driver in the cabin. The first signs of his pollution is best removed immediately, and if you feel that soon your salon will be filled with not fragrances, but in the air, small prevention does not hurt. Best of all while driving, namely, a couple of minutes before the stop, turn off the air conditioner. Having ventilated with fresh air already without heating and cooling, the air conditioner will cool down to the moment of stop, and there will be no problems with the next time it will be. This approach will reduce the amounts of cleaning and extend the ride time with its use for several weeks or even a month.
Disinfection should be carried out with open doors and even a hatch, because, airing the interior with the engine is on, you will protect yourself from moisture residues and unpleasant odor.
Simultaneously with the cleaning of the heater, the entire volume of the body of your car is also ventilated. 
Repeated disinfection is carried out inside the cabin. Thus, Lizol kills completely all bacteria, allowing you not to return more to this problem topic. Spraying the solution into air intakes, it is necessary to monitor its amount. You can not send a stream of solution into the holes of the air lines and at the same time it cannot be saved hard. The solution should fully interact with accumulated inside the air purification system moisture and bacteria.
Video "Eliminate the unpleasant smell of car air conditioner"
On records, the motorist shows how correctly at home can be cleaned with an air conditioner evaporator.
We understand the root cause and remove the unpleasant smell of the air conditioner in the car.
The problem of unpleasant odor with the subsequent inclusion of air conditioner or climate control worries, perhaps, of any car enthusiast. Someone is simply not happy with the disgusting smell, the other in addition are aware of the harm of this air.
In this article, we will look at the reasons for its occurrence, indulgence and, actually, the possibility of its removal.
And it is worth starting with the fact that the principle of operation of cooling the cabin (that the air conditioner is that climate control) is one, with the exception of temperature control. With air conditioning, you yourself decide which intensity and duration of work you need. "The climate" is doing everything for you - put the temperature, and he himself, at the expense of sensors in the cabin, it will reach and will support it.
Where does the unpleasant smell occur?
The air conditioning system is constructed in such a way that the warm air, passing through the radiator cooled by Freon, significantly reduces its temperature. This process is accompanied by condensate falling on the cooling radiator itself. The warm and wet environment creates ideal conditions for the appearance and subsequent reproduction of the colonies of bacteria. The most fruitful this process is developing when you drove with air conditioning or "climate", and then drowned the car and left.
In this case, the system stopped ventilating, and the condensate already formed in excess and bacteria arranged a feast. With the subsequent inclusion of the fan, be something with or without air conditioning, avalanche of bacteria with the incoming air fills the interior.
What's wrong with such a smell?
Many things that bad smells, but does not harm. But not in our case. The bacteria breathed by us, and even in such a concentration, significantly reduce immunity, provoking different types of respiratory diseases. It is also worth noting that a sharp decrease in the temperature of the inhaled air, as, in fact, the hypothermia itself, inevitably fraught with at least cold.
Thus, it is simply necessary to fight this smell in order to stay in health.
How to deal with him?
The most correct way is the cleaning of the evaporator in order to remove mechanically all sediments and pollution. But for this you have to make out part of the car, which is not entirely comfortable and quickly. The most optimal, but, in fact, partial solution will be special sprays for cleaning auto air conditioners. They are easy to use and do not even require partial disassembly of the car. They are a soap-chloro alcohol solution, which perfectly disinfects both the evaporator and air ducts.
Partial this solution can be called because of only a minor removal of dirt from the evaporator. Yes, the smell will disappear due to disinfection on a couple of weeks, but such a procedure is not deleted by all sediments, and therefore his secondary appearance is inevitable.
It should be understood that the timely replacement of the salon air filter is capable of significantly postpone all the above problems.
What is this cleaner in practice?
This is a very bulky spray, having a long but thin hose. Its length can sometimes reach one meter. At the end there is a sprayer.
In use, everything is simple - turn off the climatic installation, insert alternately into all air ducts the spray tube - and spray the solution. Dirt from the evaporator merges through the drain hose under the bottom of the car. After that, let's work climate (air conditioning) 15-20 minutes at maximum intensity with the enabled recirculation mode. All, cleaning is over.
conclusions
Each will decide how to overcome the problem: someone will remove the evaporator and cleaner everything thoroughly, without regretting the time. Others will be forced to resort to the help of spray. But in that case, you not only get rid of the unpleasant smell, but also worry about the health of yourself and our loved ones.

The main source provoking these rather unpleasant moments is often bacteria accumulated over time in the evaporator. And the shaft smell arising in the process of their livelihoods is not the worst result of such pollution. There are cases when microorganisms have been provoked by the driver and passengers of the disease.
All of the above are quite well-known and studied facts, and therefore, regular prophylactic cleaning of the automotive air conditioner nodes enters the list of mandatory procedures recommended by dealers for most modern foreign cars. Such prevention is guaranteed to avoid unpleasant smell in Condeya canals.
However, as evidenced by the service practice, the owners of the Iron Horses, especially used, rarely, when they themselves order this procedure. The main reason is its relatively high cost.

However, today to clean the air channels of the ventilation system, as well as the air conditioner nodes, joined it, is quite independently, due to the appearance of specialized in the Russian market. With their help, even a novice car enthusiast can carry out the so-called duodorization of air ducts with their own hands.
One of these products is the "Cleaner of the Klima Anlagen Reiniger air conditioner", developed by the chemists of the German company. Unlike a variety of other analogues presented in our market, the drug Klima Anlagen Reiniger has some functional features.
If we speak more objective, the German product is supplied to us in the cylinders of the larger volume, each such a canister has a special device in the form of a long plastic probe equipped with a sprayer. This design of the probe allows you to move it away to the internal cavities of the air ducts and process them much better than ordinary aerosols.

Experts checked the German aerosol cleaner in the case - on one of the editorial machines, in the cabin of which, when the "Condishna" was turned on, a unpleasant smell began to appear. Proted the drug and began to prepare for the procedure. As it turned out during the preparation, for the use of Klima Anlagen Reinigen, a flexible probe (or rather, its return part) should be pre-fixed on the cylinder lid.
It turned out that the probe is fixed rather tenaciously, which is very important when conducting preventive treatment. As for the composition itself, according to the attached description, it is an aqueous solution of bronophole, destroying all known, including those and dangerous to Legionella. Curious moment: the remains of the bacterial biomass after using the drug together with the liquid are removed by grades through the drainage of the air conditioner, due to which, in fact, the characteristic shaft is eliminated from the machine.

When using a cleaner, two thirds of the means are recommended to spray the evaporator, after removing the cabin filter, and the remaining third is spent on the processing of air ducts. Our experience has shown that at first stage - dismantling the filter and spraying the evaporator channel - you will need ten minutes to fifteen. Another about the same amount will go to the unhurried cleaning of all air ducts. With the help of the probe, we were processed through the central air ducts, where there were several powerful injections of cleansing spray.
Feel the unpleasant odor from the air conditioner? So it's time for his disinfection.
A modern car is not a luxury for a long time, but a means for comfortable movement. The car stuff provides for all sorts of situations: from secure parking before creating a microclimate inside the cabin. Almost any car coming from the conveyor is equipped with air conditioning or climate control systems.
Scientists have established a clear relationship between the situation in the car and driving safety and came to the conclusion that the temperature is 20-22 degrees, the level of humidity is 30-50% for humans. At temperatures above 30 degrees, the person's response slows down.
And on a hot day you can get a heat strike: so before sitting in a car, which was on the sun for a long time, it is better to open the windows, doors, blow the hot air and only after that start moving.
Provide a comfortable driving mode in hot weather can only air conditioning system.
If you feel that the air conditioner has become worse to calm down - this is the first sign that it is time to perform diagnostics and eliminate malfunctions in the air conditioning system.
However, there are such situations when it is ok, but when you turn on the air conditioner, you feel an unpleasant smell. Most often, it arises due to accumulated bacteria and fungi. To breathe them and uncomfortable, and harmful - they can cause allergic and colds. Eliminate this problem will help special tools for servicing the air conditioning systems.
Cleaners of air conditioners contain a special package of detergent additives, which eliminates various contaminants, including bacteria and fungi.
The air conditioner cleaner provides a pleasant smell, preventing the appearance of an unpleasant "dull".
By eliminating bacteria and fungi, allergic reactions are also prevented.
Household cleaners of air conditioning systems are easy to use. Consider the example of the "Airco-Fresh" cleaner "Wynns" (this drug was created on the basis of professional Clean Set (Double Treatment) PN 60605, which consists of two products: Airco Clean Pre Wash and Airco Clean Antiseptic. However This drug can only be used at maintenance stations equipped with special equipment. Therefore, in 2001, the manufacturer began to produce Airco Fresh PN30202 in a convenient aerosol packaging. Of course, in its characteristics, it is weaker than professionally, however, with periodic use (once a year) it fully justifies itself ).
Suitable for use in all air conditioning systems, both equipped with a dust filter, and not. If you have a dust filter, remove it.
The first method of use is through the engine compartment.
Remove the dust filter (Fig. 1).
Install automatic mode and maximum fan speeds (Fig. 4).
Set the temperature control to the cold air position (Fig. 3), but it is necessary to turn off the air conditioner (Fig. 2). For automatic climate control systems, set the temperature controller to the minimum position and turn on the ECO mode if possible, or disconnect the air conditioner (Fig. 2). (See Car Operation Recommendations).
Before using the tool thoroughly shake.
Spray the cleaner in air conditioning air intake
(More often it is located in the motor compartment from the passenger side) (Fig. 1).
Spray the tool for 3 minutes with an interval of 3 seconds.
The second way of use - through the interior.
Set the air output only through the central duct.
Turn on the air recirculation mode and set the maximum fan speed (Fig. 4 and 5).
Install the temperature controller to the cold air position (Fig. 3), but it is necessary to turn off the air conditioner. For automatic climate control systems, set the temperature controller to the minimum position and turn on the ECO mode if possible, or disconnect the air conditioner (Fig. 2). (See Car Operation Recommendations).
Means thoroughly shake.
Position the canister at the most powerful air intake and spray the tool for 1 minute. More often, this air intake is located under the torpedo from the passenger side (Fig. 6).
After 10 minutes you can enjoy air conditioning.
