To maintain good visibility in inclement weather, the operation of windshield wipers (the so-called wipers) is not enough. To wash away dirt flying from under the wheels of other cars, special sprayers are installed near the front window of the car. Their main problem is clogging of the calibrated holes through which clean water or non-freezing liquid is pumped. The issue can be solved in two ways: you need to clean the windshield washer nozzles or replace worn parts with new ones.
Method for cleaning windshield washer nozzles
A clean windshield is important for the driver, as it directly affects his safety, as well as the safety of passengers and other road users. That is why such parts of the car as windshield wipers (windshield wiper arms, blades), windshield washer nozzles (sprayers), and washer reservoir must always be in full working order if the car goes out on the road. Therefore, every driver must ensure that the windshield cleaning system is fully operational before setting off on the road. Please note that despite the functionality of the entire windshield cleaning system, every driver may encounter a problem. We are talking about the failure of the washer nozzles, which supply water or antifreeze liquid under pressure to the windshield. As a result, this tiny element can cause you a lot of problems, turning your trip into a nightmare. Let's find out how you can easily and simply solve the problem of cleaning your windshield washer nozzles.
Every day, millions of drivers on the road face problems cleaning their windshield due to clogged nozzles, which stop delivering windshield wiper fluid under pressure to the glass. Unfortunately, most people do not pay attention to this for a long time. This increases the risk of getting into an accident, since good visibility while driving is the basis of your safety on the road.
So, how can any car owner use a simple solution to clean their windshield washer nozzles themselves?
If the windshield wiper fluid nozzles no longer effectively supply water or antifreeze to the glass, do not consider replacing them with new ones. First, you can try to clean them. After all, perhaps they were simply clogged.
Yes, it’s easier, of course, to buy new ones, but why waste money when you can clean sprayers that will probably last for a very long time.
Here's how you can quickly clean your windshield washer nozzles without much effort.
A simple method for cleaning windshield washer nozzles
Before you start cleaning the windshield wiper fluid nozzles, you should check the functionality of the entire windshield wiper system to be sure that the reason is the lack of water supply or antifreeze fluid in the washer nozzles. After all, the reason could be, for example, the hoses coming from the washer reservoir and which could also become clogged. In this case, to clean them you need a compressor, which, by supplying air under pressure, can easily clean the wiper hoses.
In addition, it is recommended to clean the hoses that supply windshield wiper fluid to the injectors. For example, this can be done using a cleaning solution. Please note that after washing the hoses they may also become clogged. As a result, you will have to re-blow them with a compressor.
So let's move on to cleaning the washer nozzles. To clean the nozzles you will need: a syringe with a needle and enough windshield washer fluid to fill two syringes (you may need even more fluid if after two cleaning attempts the injector efficiency is not restored to 100 percent).
To clean the windshield washer nozzles, it is recommended to use a very thin needle so that you can insert it into the spray nozzle. A regular syringe (10 ml) will do.
Then do the following sequentially:
— Fill the syringe with windshield washer fluid
-Then secure the needle.
— Insert the needle into the tiny hole of the nozzle nozzle and spray the liquid with the syringe while pressing the plunger. This will force pressurized fluid into the windshield washer system. Try to pour in the liquid under maximum pressure. To do this, press the syringe plunger down as quickly as possible.
— Then clean the second injector
— Then insert the key into the ignition and press the windshield wiper lever for a few seconds (make sure that the nozzles apply the windshield wiper fluid evenly and with sufficient pressure to the glass).
- Turn on the windshield wiper blades to ensure that the glass is completely cleaned and is clean after cleaning
Please note that if you use a syringe needle that is too thick, you may change the spray direction of the nozzle!
If you do change the direction of fluid supply to the windshield, you can easily return the spray angle of the washer nozzle to its original place.
To do this, insert the needle back into the nozzle hole and move the nozzle back to its original place.
Check where the liquid is supplied to the glass by turning on the washer. If the spray angle is not ideal, repeat adjusting the position of the hole in the washer nozzle.
In principle, this is the entire process of cleaning the windshield sprayer. Of course, there are a lot of methods for cleaning windshield washer nozzles. We have described only one out of a thousand. If you know your own method for cleaning windshield sprayers, please describe it in the comments below.

Adjustment
Another important element of maintaining your car's windshield washer system is adjusting the nozzles. It is required if the jet coming out of the nozzle is directed in the wrong direction.
The process itself is simple and will take just a few minutes. And how to adjust? There is no need to remove or dismantle anything. Just do the following:
- take a regular needle or pin;
- insert it with a sharp edge into the nozzle (there are 2-3 nozzles in total);
- depending on where the jet is directed, start turning the needle in the required direction;
- if the jet goes above the glass, we turn it down, and if it sprays very low, we move up;
- left and right are adjusted in the same way.
Such manipulations are possible due to the fact that the sprayers themselves have the shape of a ball rotating inside a plastic housing. Therefore, a simple needle can act as an excellent adjustment tool.
As you can see, cleaning and adjusting the windshield sprayers on your car is very simple. You just need to monitor their condition and carry out preventive measures on time. But if the injectors completely stop working, then you will have to spend from 60 to 600 rubles, depending on the car, and replace the old devices with new ones.

How can you use citric acid to clean your car's windshield washer system in summer?
When operating a car, many experienced owners often add citric acid to the washer reservoir, which helps eliminate all possible contaminants. This prevents the occurrence of various breakdowns, the elimination of which in the future will require significant financial costs. Let's talk in more detail about whether it makes sense to add citric acid or any other chemical to the washer reservoir.
Features of using the glass washer system
Many drivers do not think about the importance of proper operation of the windshield washer system. The fact is that various contaminants that constantly appear on the glass significantly impair visibility, and accordingly, the safety of driving a car directly depends on this. In the slushy winter, you need to wash the dirt off the windows almost every couple of minutes, using not only the wipers, but also the clean water and washer fluid supply system.
This window washing system consists of an expansion tank, a powerful pump, pipes and nozzles that spray water onto the glass under high pressure, which eliminates all possible contaminants. In the cold season in winter, instead of ordinary water, a special non-freezing liquid is used, which has a low crystallization temperature, which prevents rupture of the pipes and the tank with nozzles.
The problem is that the water contains various dissolved salts and calcium, which subsequently settle on the tubes and nozzles, creating a dense calcium deposit, which ultimately disables the entire system. Therefore, to avoid such breakdowns, it is necessary to clean the washing system on a regular basis, for which special chemicals are added to the water.
Washing methods
To flush the injector, there are two solutions for cleaning the injectors:
- ultrasound procedure on a special stand;
- use of liquid.
In the first option, ceramic, old and very dirty injectors are excluded, since there is a risk of damage. Separately, after such a procedure, it is worth replacing the microfilter and sealing rings. Such parts are not cheap.
The second option involves washing the injectors without removing them from the engine. This method helps save money.
Flushing procedure
To carry out high-quality washing, you should have a second fuel pump, a container for cleaning fluid, a hose and the actual injector cleaner.
Adding rinse directly to the tank is not effective enough. Carefully remove the hoses and prepare a temporary power supply system.
Such a system, when supplying liquid to the injectors, acts as a fuel pump, but instead of gasoline it supplies the prepared solution. To create the system, a cleaner is poured into a plastic bottle. The calculation of the required quantity is related to the engine size. The template is a 2.5 liter unit, for which a liter of liquid is used. For larger volumes, the amount of solution is increased by 100 grams for every 0.5 liter of unit.
Gasoline is poured into the wash. It is taken in half the total volume of liquid. A hose is put on the bottle and secured with a clamp. The prepared fuel pump is inserted into it. The engine starts and warms up to operating condition. Next, remove the fuse from the fuel pump.
The engine is restarted. This relieves pressure from the fuel system. Then the hose is removed, through which gasoline is supplied to the injector. It is in its place that the fuel system bottle is fixed. When the fuel pump is turned on, it pumps fluid.
After running the engine for five minutes, it is allowed to rest. This time is enough to dissolve deposits on the injectors. At the next stage, the motor runs for half an hour. After disassembling the system, the engine should run for another 10 minutes. The remaining liquid burns off.
The optimal fluid for many types of engines is LIQUI MOLY. It is well suited for cleaning injectors without removing the engine. A soft effect has the disadvantage of leaving carbon deposits on the valves.
Wynn's can remove any carbon deposits and resin deposits. It is quite caustic and suitable for cars made in the 2000s. But to use it, it is necessary to check the characteristics for a particular car so as not to harm the injector.
Gentle and high-quality cleaning is provided by the less popular Carbon Clean brand.
But Laurel repeats Wynn's in its characteristics, but due to the high price it is used much less often, only it costs much more, so it is used less often.
Result of injector cleaning
As a result of flushing, the injection speed increases.
The liquid is capable of peeling off the resulting accumulations of resins, both from injectors and valves. In 30 minutes of uninterrupted supply of the solution through the injection system into the engine under pressure of up to four atmospheres, in addition to removing deposits from the injector and cleaning the walls of the combustion chamber, the injection system will be updated.
Next, the spark plugs are changed. It is also recommended to change the oil at the same time.
The advantages of flushing without removing the engine are the prevention of the fuel rail, carbon deposits are washed off from the intake valve seats. In addition, deposits are removed from the walls of the cylinder and piston, and the inlet-outlet capacity of the valves is increased.
The simplicity is that such washing on an injection engine can be done in a garage.
Most owners of cars with injection engines begin to worry if the car behaves suspiciously. The first alarm bells are the engine shaking strangely at idle. Popping noises are heard and the tachometer needle may jerk up and down randomly. Then you feel that when driving the car no longer accelerates so quickly, and the fuel from the tank seems to evaporate. Many continue to drive and put up with the unsatisfactory condition of the car. It’s worse when the engine shakes so much that vibrations go through the car body. Such a malfunction is difficult not to notice. But experienced motorists know that flushing the injector would quickly eliminate the problems and bring the engine into a healthy state. The cause of engine malfunctions is contamination of the fuel supply system. Dust, sand, and water that enter the tank are easily retained by the fuel filter. But after replacing it, the situation may not change. Then we can confidently diagnose contamination of the injectors and intake manifold.
Using ready-made chemicals or citric acid
In auto chemical stores you can find various specialized products, the main purpose of which is to eliminate such dense calcium formations and clean the windshield washer system. Despite their effectiveness, such products are still not widely used on the market, which is explained by their high cost. Therefore, you should not be surprised by the fact that many car owners use improvised means the old fashioned way, especially since they are completely safe and effective.
One of these time-tested folk recipes for cleaning the washer reservoir and the entire system is citric acid. The cost of lemon juice is minimal, and provided that the maximum permissible dosages are observed, plaque can be completely eliminated, returning the original elasticity to the pipes. The use of such a chemical allows you to remove contaminants from the spray nozzles, which again efficiently wash the windshield, ensuring its complete cleaning.
Citric acid effectively breaks down various solid deposits; it is an inexpensive and completely safe product to use. All you need to do is add a small amount of lemon juice to the water in the expansion tank, then lightly spray the glass with water so that the cleaning solution reaches all tubes and spray nozzles. It will be necessary to let this liquid work for several days, which will be enough to completely remove the existing plaque.
The undoubted advantage of using such citric acid is its minimal aggressiveness, which eliminates the possibility of damage to the paintwork at an increased concentration of the solution. However, remember that you should not use pure lemon for such cleaning, so it must be diluted with water, at least in a one-to-one consistency.
As an alternative to citric acid, you can use Coca-Cola, which does not contain sugar. It contains a small amount of phosphoric acid, which perfectly removes all dense deposits and cleans the washer fluid reservoir. Literally a half-liter bottle of Coca-Cola is enough to completely eliminate existing plaque. This service should be carried out at least once a year.
Let's sum it up
During the operation of the vehicle, a small dense deposit appears on the pipes and nozzles in the glass washer system, which significantly reduces the permeability, makes the tubes brittle, and, ultimately, leads to the need to replace the pump and expensive nozzles. To avoid such problems, it is necessary to clean the washer reservoir annually by pouring a solution of citric acid, Coca-Cola, or various purchased specialized cleaning compounds into it.

Advantages and disadvantages
There is nothing wrong with driving a car with classic jet injectors. They also have certain advantages and have a number of advantages.
You can think about a replacement if the advantages of fan systems outweigh the possible disadvantages.
Fan nozzles have several key advantages:
- uniform distribution of washer fluid. When water is supplied, it falls on the surface of the windshield in a dense layer of small drops. Distribution occurs over the entire surface covered by the windshield wipers, and sometimes even beyond it. This already depends on the settings. Separate jets pour the bulk of the liquid onto one zone, skipping other areas. This makes the wipers do a worse job of removing dirt,
- The efficiency of the windshield wiper blades increases. This follows from the first advantage, since the wipers move along the wetted surface along their entire working area. The jet leaves behind dry and dirty areas. Because of this, wipers have to walk part of the way through dry dust and dirt,
- Fans do a better job of removing dried insects and stuck-on solid dirt. Some people find that the jet removes hard dirt better. In fact, small drops fall on the entire surface of the dirt, soften it faster and help the wipers complete cleaning,
- the number of scratches produced is reduced. When the wiper passes over a dry surface that the jet of a classic nozzle has failed to moisten, the brush scratches the glass. If there is a layer of dust or dirt, the abrasive properties increase significantly. As a result, the windshield becomes covered with small scratches and its attractive appearance is gradually lost.
- Windshield washer fluid consumption decreases. This does not happen on all cars, but on most vehicles. Although washer fluid is not the most expensive consumable, even such savings are important.
Some will say that you have to pay for such benefits. But no, the price is quite reasonable. Fan-type injectors do not cost much more than jet nozzles, so you won’t have to spend a fortune on them. Cost cannot be considered a disadvantage.
But fans do have disadvantages. There are two main negative points here.
- Freezing. Due to the peculiarities of its design, the fan nozzle is less protected from negative temperatures. Therefore, they are capable of freezing more often than their inkjet counterparts. To solve this problem, special nozzles equipped with a heating system have been developed. If you live in a region with very cold winters, it makes sense to install heating. In such conditions, even jet models can freeze, so it’s not worth calling this drawback purely the prerogative of fan sprayers.
- Covering a large area of the windshield with water. Advantage sometimes acts as a disadvantage. Since the entire glass is covered with small drops, until the windshield wiper passes over it, the driver’s visibility of the road is impaired. Under difficult conditions, even a second loss of control over the situation can cause the driver to act incorrectly. But this minus is conditional. With the correct setting of the wipers, the driver quickly gets a good view after applying a spray of liquid from the windshield washer reservoir.
Despite the conventionality of the disadvantages, they should also be taken into account when choosing the optimal injector option for your vehicle.
If you are completely satisfied with the fan devices, this will be a great addition to the windshield wipers on your car. But you will also have to learn how to clean and adjust the fans yourself. There is nothing complicated about this, because every car owner must cope with the task.
Peugeot 206 1.6 on the handle › Logbook › Flushing the windshield washer system
I used to stutter a couple of times about cleaning the windshield washer on my car, now I’m telling you the details,
We need to start with the fact that since 2003, the Pyzhi 206 has been equipped with very clever sprayers (jets) on the windshield washers: the old ones pour two streams onto the glass, and the new ones spray water evenly in a certain sector, which allows you to wash the glass much more efficiently, economically and quickly .
By the way, the guys from the tire shops, whom I pestered about blowing out the clogged sprayers with compressed air, said that they only have 2-3 atmospheres and this simply is not enough: 5-6 atmospheres are needed, which is usually what those who do painting have. In the end, I never got to the second one. However, this gives us an idea of the pressure required for blowing: no vacuum cleaner or tap water pressure can handle this, not to mention “blowing with your mouth.”
