Which carburetor cleaner is better

A carburetor is an important element of an internal combustion engine, designed to prepare a combustible mixture. The serviceability of the engine and the reliability of the vehicle depend on its technical condition and cleanliness. In the article you will learn about methods for flushing this unit, the best means for this procedure, and you can also read about “folk” methods for cleaning the carburetor.

Features and types of cleaners

The main advantage of products for cleaning the carburetor and its parts is that, due to their composition, carbon deposits and dirt on the parts gradually soften. Modern carb cleaners serve not only as a cleaner, but also as a kind of lubricant for carb units that are in constant motion. The cleaner also covers the parts with a protective film, increasing their service life.

All carb cleaners are highly flammable. When working with the cleaner, you must follow all fire safety rules. The work area must be well ventilated.

Modern carbliners are available in two forms:

The method of application of these two forms differs. Some cleaners are suitable for manual use, while others are suitable for automatic use. In manual mode aerosols and sprays ; they are equipped with special tube attachments. The length of the nozzle allows you to spray the cleaner in the most difficult to reach places. Today, sprays are most popular among car enthusiasts.

The second form of release of the purifier is liquid. The use of cleaning liquid is considered to be automatic, since the process takes place directly without human intervention. The product is poured into the fuel tank, where the carbocleaner is mixed with fuel and enters the carburetor. During the combustion of gasoline, cleaning components are released into the carb, helping to soften and gradually remove contaminants. Carbon deposits are removed through the exhaust pipe.

Selecting a cleaner

Carburetor cleaner - which one is better to choose? This question worries every car enthusiast. There is a wide selection of cleaners on the automotive market, the most popular are:

liqui moly (spray);
ravenol carb (spray);
xado jet 100 ultra (spray);
mannol 9970 (spray);
hi gear (liquid).

Carburetor cleaners (composition) have almost identical components:

acetone;
Tuluene;
benzene;
acids;
organic compounds;
inorganic compounds.

Descriptions of cleaners vary. Liqui moly is considered a high-quality and quite popular cleaner. It is used not only for cleaning parts from carbon deposits, but also for cleaning channels, throttle valves and injectors. Ravenol carb quickly removes carbon deposits from intake valves, piston crowns, throttle valves and carburetor channels. Xado jet 100 ultra is considered a universal carb cleaner.

Mannol 9970 provides high-quality cleaning of all carb parts and is capable of cleaning high-temperature carbon deposits. Responsible for optimizing fuel consumption. Recommended for cleaning two- to four-stroke gasoline engines. Hi gear carefully removes dirt, avoids breakdowns and expensive repairs.

Cleaning with a carb cleaner is considered to be a preventive measure; it only extends the service life of the carburetor.

Instructions for use

The algorithm of action when working with aerosols is approximately the same. In most cases, dismantling the carburetor is required. Step-by-step carb cleaning:

remove the carb and disassemble;
a cleaner is applied to the surface of each part;
leave the sprayed parts for 5-10 minutes;
Use a brush or rag to remove soaked carbon deposits.

Cleaning the carburetor is a simple task. When carrying out this kind of event, it is important not to lose parts of the mechanism.

What's the result?

Considering all of the above, it is obvious that even with the relative simplicity of the carburetor design, it still requires additional timely maintenance. To keep the unit clean and in good working order, some experts recommend cleaning and adjusting the carburetor at least twice a year. It is recommended to do this in the off-season, that is, before the onset of severe frosts or warm weather. This measure allows you to maintain fuel consumption at an optimal level.

If you notice noticeable sagging when you press the accelerator pedal, then in parallel with cleaning the carburetor itself, remove the carburetor cover, and then pay attention to the accelerator pump nozzle. This element must be thoroughly cleaned with a carbon cleaner; in addition, it can be blown with compressed air from a compressor.

It should also be added that cleaning without dismantling and disassembling using various cleaners is more effective in case of downtime problems, and also helps to externally clean the surfaces of the carburetor itself from dirt.

In other situations, it is best to disassemble and clean the dispenser as quickly as possible. This also applies if the carburetor is for some reason very dirty or has never been cleaned before.

Consumer Reviews

Reviews from professional auto mechanics about the above products are positive. Masters note that with the help of cleaners, cleaning takes much less time.

I have been using aerosols to clean carburetors for a long time. My work is directly related to cars, so the use of special tools allows me to significantly reduce repair time. Spray cleaners allow you to effortlessly clean dirt and carbon deposits from fuel combustion. Liqui moly is considered the most popular; it allows you not only to clean all parts, but also to lubricate all moving parts.

Car enthusiasts who prefer not to contact specialists and carry out cleaning on their own note:

Aerosols themselves are very convenient to use. After 5-10 thousand kilometers, I try to clean the carburetor to extend its service life. With modern means this is very easy to do; the nozzle helps to spray the cleaner onto the necessary parts without dismantling the carburetor.

Carburetor clogging with carbon deposits is an inevitable occurrence. Over time, they are deposited in different parts of the system, complicating its functioning. This leads to engine interruptions and uneven idling. More fuel is consumed, and the toxicity of exhaust gases increases. In such a situation, cleaning the carburetor will help. Hi-Gear carburetor cleaner will help you do this.

Indications for cleaning

The fuel used to operate vehicles is often not of high quality.
It contains water, dirt and products that can cause corrosion. They cause pollution. Flush the carburetor in several cases:

If lowering the power unit becomes difficult.
If you press the accelerator pedal, there will be a delay.
The engine does not idle well.
You're using too much fuel.

It is worth noting that all this may indicate other vehicle malfunctions, for example, malfunctions in the ignition system. But in any case, cleaning the carburetor will be appropriate. This is especially true in cases where it has not been carried out for more than a year.

To properly wash the carburetor, you need to remember one feature. This device consists of several small parts. For some of them, rinsing will be sufficient. Others will also need to be cleaned.

With smaller elements other difficulties may arise. Take, for example, attachments with 2mm channels. Cleaning them will be problematic. In this case, it is necessary to blow with compressed air. But before that, it is better to soak the parts in some solvent. The same applies to large elements.

Carburetor Cleaner

Another effective aerosol product with excellent reviews (most motorists note the high effectiveness of the spray). It efficiently removes various types of deposits, restoring the operation and performance of even a heavily contaminated carburetor without resorting to disassembling it.

Purpose and compatibility

The purpose of this drug is to clean the carburetor in those parts and elements that cannot be cleaned using standard detergent additives poured into the tank. It will serve as an excellent addition to them for complete cleaning of the fuel system.

Action

This is what this aerosol does:

effective removal of deposits and contaminants from the internal surfaces of the carburetor, from its channels and holes;
neutralization of the harmful effects of using low-quality fuel;
reducing the harmfulness of exhaust gases.

A clean carburetor works longer and better, the engine becomes more responsive, and starts easier – even in winter.

Application

To restore smooth idle speed, cleaning the outside of the carburetor is not enough. Its channels need to be cleaned. Decarbonization with carb cleaner is carried out as follows:

clean the outside of the carburetor (as is the case with a synthetic cleaner);
with the engine running, unscrew the economizer solenoid valve (EPV);
inject the aerosol into the mounting hole;
return the valve to its place;
rev it up a few times.

After this, use cleaning additives that are poured into the fuel tank.

In order not to stumble upon a counterfeit composition, remember the article number of the product.

Other washing methods

Sometimes there is no special cleaner for the control panel nearby. In these cases, solvent No. 646 can help. However, don't rely on it too much. The efficiency of this cleaning method is quite low; moreover, it is able to remove dirt from the surface of the carburetor only for a short time.

The proper functioning of this part depends not only on how often it is cleaned, but also on the product used. In order not to make a mistake when choosing this product, you need to carefully read in the store about its composition and properties. It is imperative to consider the activities involved in using the cleaning product. In addition, we should not forget that all elements of the fuel system must be cleaned regularly. To ensure proper functioning of the carburetor, it is recommended to clean it every 10-15 thousand kilometers.

Trouble-free operation of a car depends on many components, not the least of which is the carburetor. Every car owner should regularly check its condition. This is especially true for those who use low-quality fuel. This factor increases the likelihood of clogging by an order of magnitude. But you can avoid the negative consequences caused by a dirty carburetor if you clean it regularly.

Every car owner can handle this task with his own hands, so you don’t even have to turn to specialists for help. Only when disassembling this power supply is it necessary to remember the location of the main parts. But first you need to understand the best way to flush the carburetor.

This must be a special composition designed to remove contaminants from the internal and external surfaces of the working unit. It is not recommended to save on the purchase of cleaning fluid, otherwise this may soon cause new, even more serious problems for the car enthusiast, which will require not only more time, but also greater financial costs.

Expert advice

The main harm of deposits that appear in the system is that these products interfere with the process of normal mixture formation. Consequently, fuel burns worse and more is required. In this case, the dynamics of the vehicle suffers. An effective way to correct the situation without disassembling the system is to use cleaners.

Is it possible to wash it at home without special products?

If you do not have the opportunity to use special carburetor cleaning products, you can do it without them. Simply soak the necessary parts in kerosene (gasoline, acetone) overnight and start cleaning and cleaning them in the morning. With the right approach, the effect will not be worse. But under no circumstances follow the advice of “experts” who recommend pouring acetone into the tank or carburetor to clean the fuel system! Yes, acetone is great for dissolving and removing dirt, grime, paint residue and even water. But it also dissolves plastic and rubber seals, gaskets and valves!

As you can see, washing a carburetor with your own hands is not at all difficult. The main thing is to have a good cleaner, the necessary tools and a few hours of free time. And to prevent this process from becoming habitual, fill only high-quality fuel into the tank of your car.

Which carburetor cleaning spray is best to buy?

So let's get back to purifiers. When choosing a liquid in a tank or aerosol can for cleaning carburetor systems, you should study the instructions and recommendations of the manufacturer of a particular product. This will allow you to study in advance the possible nuances associated with the use of a specific composition. Since cleaning the carburetor manually is the most effective way, we will focus on aerosol products.

These compositions are based on organic substances, various solvents and groups of inorganic compounds. The active components are responsible for dissolving, softening and washing away deposits. Additional properties such as lubrication, anti-corrosion, etc. provide special additives. The more active chemical compounds that are included in the cleaner, the more effective the carburetor cleaner will work. In other words, the impact will be on the widest possible range of different types of pollution. If the product does not contain components for removing complex (for example, tarry) deposits, then the cleaning efficiency after its use is reduced. The solvent in an aerosol cleaner is usually gasoline or organic based. The type of solvent determines the duration of action of the cleaner, the degree of its effect on the carburetor elements and the overall quality of cleaning.

The right decision in such a situation would be to choose products from a manufacturer that has a good reputation and is a well-known market participant. At the same time, you should study customer reviews about the product, and also look for additional information about it. The fact is that tests of carburetor cleaners are often carried out by various printed publications; test results can often be found on the Internet. This will help you decide on the choice of a particular product.

Based on the test results, among carburetor cleaners we should highlight the Liqui Moly product, which can effectively remove stubborn dirt, remove varnish deposits, clean channels, jets and throttle valves. This product goes on sale in an aerosol can, which allows for external and internal cleaning, washing the carburetor body, etc.

As you know, you can find quite a lot of carburetor cars on domestic roads. Their main advantages are rightly considered to be affordable price, simplicity of design and maintenance, and unpretentiousness to the quality of engine oil and fuel. In parallel with this, one of the weak points of such cars is the engine power system, or more precisely, the carburetor.

We also recommend reading the article about what a carburetor dosing system is. From this article you will learn about the design, principles and features of the carburetor.

Today there are a large number of carburetor cleaning products on the market. Similar products are found in specialized auto stores, in auto goods departments in large shopping centers, at gas stations, etc. Taking into account the variety and price range, it is logical that every car owner strives to purchase a good carburetor cleaner inexpensively, which will effectively remove all contaminants without harming the dosing device. In this article we will talk about which carburetor cleaner to choose, and also answer the question of how to clean a carburetor with carburetor cleaner correctly.

Why and when you need to clean the carburetor

Let's start with the fact that carburetor injection, like any other metering system in the general power supply circuit of an internal combustion engine, is located in the engine compartment and constantly interacts with the components of the fuel mixture (fuel and air). Also, a carburetor is a mechanical device that consists of a number of moving parts. Some elements are open and subject to significant contamination along with the general contamination of the engine compartment.

If the pollution is strong, then the following symptoms occur:

power decreases and fuel consumption increases noticeably;
smoke, increased toxicity of exhaust gases;
difficulty starting a cold and/or hot engine;
unstable operation at idle, the speed fluctuates, the engine troits;
failures during acceleration, slow response to the gas pedal, etc.

Please note that these symptoms may also occur for other reasons. To eliminate possible problems, the motor requires diagnostics. In parallel with this, on carburetor cars, the metering device is still a common culprit. If this is the case, then you need to clean the carburetor, that is, you will need to use special equipment. To effectively remove contaminants, you must use a high-quality cleaner. In such a situation, you can either deliver the car to a service station or clean the carburetor yourself, deciding on the choice of cleaning agent.

Carburetor cleaners

Before the rapid development of the auto chemical market, many drivers made carburetor cleaner with their own hands, since there were simply no other options. Most often, diesel fuel and kerosene were used for this task, and their cheapness and availability allowed everyone to wash their carburetor. Some also experimented with different solvents, acetone, etc.

Today, there is no need for such actions, since special compounds for cleaning the carburetor are available at any auto store. As for the efficiency of their work, the end results are much superior in terms of cleaning quality to the use of, for example, diesel fuel. Moreover, the cleaners contain a number of additives that allow you to remove contaminants without the risk of damaging the mechanical elements of the device. Let us add that, as before, every car owner can use carburetor cleaner, since the price of such products remains quite affordable.

There are two types of formulations available for sale:

special cleaning liquid;
cleaners in aerosol cans;

The use of these solutions involves self-cleaning of dirt or manual removal of dirt after treatment with a cleaner. In the first case, removal/disassembly of the carburetor and other elements of the fuel system is not expected, since the cleaning fluid is poured into the fuel tank. Next, the composition is mixed with fuel, after which the cleaner enters the carburetor along with the fuel naturally, removing dirt and deposits occurs gradually.

The disadvantages of this method rightly include the duration and effectiveness of such cleaning, since the car must travel several tens of kilometers to obtain results. As for quality, this method is much less effective than cleaning the carburetor with disassembling the device and is rightly considered a preventive measure. For these reasons, manual cleaning using aerosols is much more popular.

Homemade carb cleaner

Costs: 173 rub.

Carburetors have been used in the automotive industry for decades, and during this time, craftsmen managed to invent their own recipe for a drug that could be used to clean such units. To prepare such a product you will need:

acetone;
Gasoline Galosh;
White Spirit.

These three substances are mixed in equal parts, approximately 33% each. The result is, of course, not Liqui Moly. However, the liquid produced in this way can be successfully used to decarbonize the carburetor instead of professional means. The exception is cases with a heavily contaminated vehicle fuel system.

In addition, you can wash the metal parts of the carburetor with a “garage” cleaner. For other elements of the device, it is better to use just gasoline.

Conclusion

In fact, a modern car with a carburetor on board is a rarity. Owners of classic cars equipped with these devices may find one of the above-described drugs very useful. For the most part, they have universal use, but only for preventive purposes. The use of even an expensive cleaner cannot be an alternative to full maintenance of the fuel system with its diagnostics, flushing and tuning.

How to use carburetor cleaner

A special composition, which many call “carbicleaner,” is supplied in pressurized cylinders. There is also a dispenser and a special device in the form of a thin tube-nozzle, which allows you to apply the product to different surfaces, taking into account access features.

Attention! Carburetor cleaners are flammable. For this reason, safety precautions must be observed when applying them! Do not use the product in areas with poor ventilation, near potential sources of ignition, etc.!

This cleaning method requires partial disassembly of the carburetor, after which the elements of the device are processed manually. The result is to remove maximum contaminants from both external and internal surfaces.

We also recommend reading the article on how to clean the carburetor without disassembling it and removing it from the car. From this article you will learn about available methods for cleaning the carburetor directly on the car.

Once a carburetor cleaner has been selected, the application and cleaning process itself consists of spraying the product onto the surface of the parts. External carburetor cleaning is usually done before the cleaner is applied to the internal parts. First, the air filter cover is removed, the filter element is removed, after which the carburetor is actively washed from the outside. At the same time, the mesh filter is also cleaned, which requires cleaning every 40-50 thousand kilometers. Then you can begin processing internal elements, cleaning dampers, channels, etc.

Which carburetor cleaning spray is best to buy?

Based on the test results, among carburetor cleaners we should highlight the Liqui Moly product, which can effectively remove stubborn dirt, remove varnish deposits, clean channels, jets and throttle valves. This product goes on sale in an aerosol can, which allows for external and internal cleaning, washing the carburetor body, etc.
You can also pay attention to the product of the company Mannol. The carburetor cleaner from this company removes carbon deposits and deposits well, and washes away dirt from the body, throttle valves, jets and other elements. If you use such a cleaner with a certain frequency, then you can talk about a general improvement in the performance of the fuel system. The product is also used not only for the carburetor, but also to remove dirt from other internal combustion engine parts.
A fairly popular and widespread solution is Hi-Gear carburetor cleaner. Tests of products of this brand have confirmed that the composition effectively removes carbon deposits and all kinds of soot. This became possible due to the fact that the manufacturer developed a special synthetic formula. The company offers several types of cleaners, which differ in the aggressiveness of their impact on different elements, allowing you to clean the carburetor without disassembly.
Car enthusiasts also recommend ZM brand products. The carburetor cleaner of this brand not only removes all types of contaminants, but also lubricates mechanical components. The product consists of 2/3 volatile organic compounds that are harmless to the environment. Such a solution can also be considered universal, since it is used not only for cleaning carburetor systems, but also for cleaning the crankcase ventilation, as well as a number of other elements.
Let us add that the Jet 100 Ultra carburetor cleaner is in good demand. This aerosol is used to treat the dosing device both externally and internally. The product is quite active and allows you to quickly remove contaminants in the form of oil and gasoline films, dirt, deposits, varnishes, carbon deposits, etc. In parallel with this, the solution has good lubricating abilities.
