Rust cleaner with el contacts. Liquid for cleaning and protecting contacts Composition. Hi-Gear HG5507 - Protection of the high voltage part of the ignition

What and how to clean contacts? Why, in general, do I need processing, protection and lubrication of contacts? Reply to these and other questions in this small article.

It so much that the electrical equipment system is slightly deprived of the part of the car owners and remember it only when either the next lamp went into the world forever extreme things, or when at the most inappropriate moment the starter does not respond to the rotation of the ignition key.

It is also worth noting that the fault of the faulty wiring happens more than all the fires of cars and occurs instantly and unpredictable.

Therefore, the electrical equipment system, like all other car systems, requires regular maintenance.

Moreover, in our time this procedure is even more important than before. This is explained by two reasons:

• cars have literally stuffed with electronics
• applying engine control systems

Well, with the first reason it is clear - the more wires, the more possible problems.

Why does the engine control system require high attention?

This is due to the use of lower voltage in the wiring of the engine control system and the use of pulse signals.

The thing is that the higher the voltage - the smaller the loss.

And what do we get? Previously, only 12V or, on some - 24V, was used in the electrical equipment. And now the ECU works mainly with a voltage of only 5V, and some sensors are completely with Milvoluts.

The ignition systems have become more powerful and are no longer controlled by non-banal closure / opening of contacts, and pulses of a certain duration defined by the control unit.

All these minimal chains should always have a minimal and constant resistance, and they work in constant temperature drops among the washesized and dusty air under the hood. Condensate, puddles on the roads, constant vibration and corrosion inevitably make their own adjustments to the system.

I can confidently say that the lion's share of all problems in the engine control system is related to the state of the wiring.

And most weak link In this chain are all sorts of contacts and connecting blocks.

What to clean and protect contacts?

All contacts sooner or later begin to corrode and coated with other oxides, violating the system.

Therefore, the question arises logical - what and how to clean the contacts?

The mechanical way to clean the contacts is extremely not desirable. Yes, and in modern systems they do not fit to them. Folk methods with eraser, soda and the like do not give the desired result. And the use of these ancient methods in the 21st century I consider the struggle with windmills.

I, as a radio mechanic, have long used modern chemistry in solving these tasks. The same chemistry broke with success in the automotive industry.

From practice, as for me, special attention Deserve two such funds.

Electrical Contact Lubrication

One of them is contact 61.

And the second - Liqui Moly. Electronic-Spray.

This is a means for cleaning, lubricating and protecting all sorts of electrical contacts as low voltage and high

The price tag for these funds is not quite budget - 200ml worth 180-200 UAH. (approximately 8 American money). But it is worth it, believe me. Moreover, it will be enough for him very and very long.

One processing is enough for a minimum for a year, so once spent time spent time will give you confidence for the whole year that in the most responsible moment the contacts in the wiring will not be submitted.

About Liqui Moly Electronic-Spray completely little information on the Internet and other sources. Therefore, reasonably many questions arise from many. One of the main - does this tool spend and whether there will be no closures and leakage currents?

I used it for a long time and I can say that it is quite the opposite, it prevents wandering currents, current leaks, heating contacts, sparking, as it improves contact, filling microscopic cracks and roughness on contacts.

I find it use where only you can - Contacts Avtogynitolas, connectors of all sorts of sensors, terminals, terminals rechargeable battery, contacts lamps, transition connectors, switches and switches, ignition system, etc. And it is only in the car! And in the everyday life and repair of all kinds of techniques of applications is no less.

There was a case with a car VAZ. The man asked to see where the signals of turns were missing. He spent all day to find a problem, replaced already stealless switches, and the problem was not solved.

In five minutes, I simply processed an alarm button with such a means and returned a flashing type of car even without replacing the button!

To use this spray is very simple. If the contacts are not very dirty, then the pixyat is completely a bit for contacts and connect the connector into place. If the contacts are dirty, then also pshikham and wait for the rapid reaction with the release of foam and connect everything back. If the contacts are very dirty, then pshikam, we are waiting for 10-15 minutes, we remove the mud or squeezed air and repeat the processing again. But the last option is extremely rare and usually everything is cleared from the first time.

There are means separately for cleaning, separately for lubrication and separately to protect and displace moisture. For example, a series of contact has a lot of them, sharpened under a certain task. Kontakt U - Purifier Purifier and Fluses, Kontakt S - Cleaner contacts from oxides and sulfur connections, Kontakt 60 - Anticorrosive Contact Protection, etc.

But the means of Kontakt 61 and Liqui Moly Electronic-Spray are positioned as universal. So to speak, the budget option.

The price and properties of them are almost the same, so you choose, solve yourself.

Attention! Be careful and always give a report to your actions. In this article, we are talking about a universal means to protect contacts with a slight cleaning effect! There are funds for sale for cleaning contacts. Whether in ignorance, or on negligence, but sellers do not warn that after the contact cleaner, the contacts must be protected to protect the contacts !!! Otherwise, the contacts are "green" and the processed surfaces are literally corrosive. Including the board in the engine control unit. The car becomes unsuitable for operation and requires expensive repairs. There are no little such cases. Be careful! I mentioned this in the video at the end of this article.

How to Clean Contacts

First of all, I advise you to handle the detonation sensor connector and connecting other low-voltage sensors.

Attention! I do not advise you to process the oxygen sensor connector in this way! The reasons are set forth in the article about

Battery terminals.

It is worth noting that for terminals there is a special lubricant in LiQui Moly Tubes "Batterie-Pol-Fett". But I only use spray.

Connecting Pad Wiring Harness

Well, of course, the connector of the ECU itself

You also need to pay attention to air and coolant sensors, position sensor contacts distributional shafts, generator and starter. Well, and necessarily

Separately, I want to stop on the elements of the ignition system.

Processing contacts high voltage wires And the ignition coils must be performed at one first. As for prevention, so and if there are failures and surveillance in your car harsh pressed Gas pedals. The thing is that if there are problems in the ignition system, they will manifest themselves with sharp pedaling. This is due to the fact that several factors affect the magnitude of the breakdown voltage and one of them is pressure.

On the idling The pressure in the cylinders is not large, but at the time of opening throttle valve It increases sharply, increasing the breakdown voltage on the candle electrodes. And if there is a defect in the ignition system, then it will definitely show its influence at this moment. Talk about it in one of the nearest articles.

So, one of these defects is often a slightly increased resistance of contacts in Wires and, especially, in low-voltage connectors of the ignition coils. And the usual multimeter will not show this.

And very often cleaning and protecting contacts helps to correct the situation. Business for three minutes, and the result will be 100% for the better!

Especially if the car is more than three years, then this procedure is simply obligatory.

First of all process low-voltage contacts ignition coil. Remove the block and apply spray

Next, lubricate high-voltage contacts. To do this, it is not necessary to pour the cleaner into the conclusions of the coil, and it is enough to apply the remedy on the BB of the wire, put it on the coil terminal and slightly twist there. It is also necessary to hold the wire with contact up so that the spray penetrate deeper - in the place of the connection of the tip with the wire itself

We also do the same on the other end of the wire

This procedure I advise you to do even on new wires and coils.

The same applies to other contacts and connections. If you put a new sensor or connect a new automagnetol - apply spray to contacts. After all, the main task of these funds is not only in cleaning, but also in the creation of a microscopic protective film on contacts. This film protects contact from moisture and air, preventing oxides and corrosion.

And do not forget about mounting blocks Fuses and relays. Pulled out relays, handled the connector and inserted back. Nothing cunning

After these uncomplicated procedures, you will definitely notice that the behavior of the car has changed for the better! And the engine control system, electrical equipment and the ignition system will work easier, which will turn into an enlarged resource of the entire engine as a whole.

Here are video about processing and protection of contacts

All peace and smooth roads !!!

Cleaner contacts Allows not only to get rid of dirt and rust on the current parts of the car's electrical circuits, but also improve contacts, so that they did not overheat and ensure reliable operation of the electrical system of the machine. Some tools for cleaning contacts in the car also have a preventive effect so that the contacts processed by them in the future are not so subjected to pollution and oxidation.

The market presents a wide variety of electric contact cleaners. As a rule, they are implemented in two aggregate states - in the form of fluid and in the form of spray. The first type is suitable, rather, for point processing, while it is better to handle a large area, that is, several contacts at the same time. However, in the package to most sprays there is a thin tube, which also allows you to point to apply. In addition, it can be reached to hard-to-reach places.

As for the range, it is wide enough, but ten cleaners are most popular among domestic car owners. electronic contacts - WD-40 Specialist, Liqui Moly, Abro, Kontakt 60 and others. Next is given full list and a detailed description with an indication, efficiency, operational features and prices.

Properties and Functions of Cleaners

When choosing one or another contact oxide cleaner in electrical scheme Car must define with what properties should be the optimal agent. Ideally, the cleaner must:

• effectively launder dirt and / or corrosion from electrical contacts, terminal and bolted connections, twists and other elements of the electric system of the car;
• do not dissolve the lacquer coating on chips;
• prevent the appearance of wandering currents, its leaks, sparking, heating contacts and improving their quality (usually it is achieved by the fact that the elements are included in the contact cleaners to fill the roughness on their damaged surfaces);
• do not contain in its composition silicone (or similar insulating compounds);
• to give a car enthusiast ease of use (here you need to choose between a liquid cleaner and aerosol);
• quickly dry after applying.

Often, automobile contact cleaners can be used in household electrical engineering. However, it is important to take into account how much the tool is calculated, because in household outlets, the voltage is much higher than in electrical system car!

The above properties provide him with the ability to effectively perform the functions assigned to it to which:

• cleaning electrical contacts from various contaminants, dust, dirt, aggressive chemical elements, and so on;
• protection of contact elements from corrosion (both from both water and chemical, which may occur under the influence of electrolytes, acids and other compounds);
• effective removal of oxide and sulfide deposits (i.e., corrosion caused by moisture and / or chemical reagents);
• reducing the electrical resistance of contact compounds, that is, preventing their overheating and load on their external isolation.

Modern manufacturers of contact cleaners offer their consumers as narrowly specialized (cleaning), and universal (which other protective properties are also equipped with cleaning properties.

What and how to process in the car electrical system

Now, when it became clear what means it is better to use to eliminate pollution and corrosion in places of electrical connections, it makes sense to discuss the question of which distress places in the car must be processed with their help. In this case, the information has a recommendatory nature, and the fact of processing or not processing depends on the state of the contact. That is, it is just a preventive measure. So, with the help of the cleaner contacts from oxidation makes sense to process:

• contacts Avtogynitola;
• sensor connectors (detonation, DDA in the intake manifold, air temperature and coolant);
• limit switches;
• rechargeable battery terminals;
• contact connections of lamps (external and internal);
• transition connectors;
• switches / switches;
• throttle knob;
• connectors and contacts nozzles;
• connection block of wiring harness;
• absorber valve contacts;
• fuse connectors and relays;
• connectors directly electronic block Engine control (ECU).

Mandatory in preventive purposes it is necessary to process contacts in the ignition system, especially if problems are observed in its work. It is processed both low-voltage and high-voltage contacts.

Cannot handle contact cleaner oxygen sensor connector!

The processing of electrical contacts in this case should be performed in strict accordance with the instructions given or on the packaging of information. Be sure to read it to the use of the fund, and not after! However, in most cases, the traditional algorithm - it is necessary to apply a certain amount of cleaning agent on polluted contact, and then wait for a short time in order to give a substance to absorb. Further, when a chemical reaction occurs and dirt / corrosion, it is possible to remove them with a vein, napkins or tassels from the surface of the electrical contact.

In particularly launched cases (or when the cleaning agent is ineffective), the situation is possible when it is necessary to process the electrical contacts two, and then three times. If dirt / corrosion on contacts are a bit, then instead of the vet, you can use the air compressor, with which you can simply blow mud deposits.

Often, before using a special cleaning agent, it makes sense to perform a mechanical processing of an oxidized (contaminated) surface. You can make it using sandpaper, brushes or other similar tools. This will save the consumption of the contact cleaner, and therefore money. However, remember that it is possible to do this only if you are sure that you do not harm the electric contact or another element of the scheme.

Contact Purifier do-it-yourself

The medium-listed means although they help to quickly and efficiently get rid of dirt and / or corrosion on electrical contacts, thereby improving their conductivity, but they all have a significant drawback - a relatively high price. Accordingly, buy for laundering a couple-triple problem seats It does not make any sense. Instead, it is better to take advantage of one of the "folk" methods and means that there is actually a lot. We give the most common and effective of them.

Recipe number one. It takes 250 ml of aqueous concentrated ammonia and 750 ml of methanol (pay attention, methanol is harmful to the human body) or ethyl alcohol, which is denatured by gasoline. You need to mix these two substances in a glass vessel, which has a hermetic lid. The composition can be used to clean electrical contacts, and it is necessary to store it in a closed form, away from heat sources and not under the influence of sunlight.

Recipe number two. About 20 ... 50 ml of medical vaseline oil should be dissolved in 950 ml of extraction gasoline, after which mix well until complete dissolution. The composition can also be used for cleaning. Store similarly, away from heat sources and sun rays.

Even for cleaning contacts, you can use the following means ...

Cleaning paste "Asidol" (one of the species)

Eraser. With the help of an ordinary stationery, especially if its composition has small-cell elements. However, for deep contaminants, this method will not fit.

Solution food Soda . Its composition can be prepared from the proportion of 0.5 liters of water 1 ... 2 tablespoons of soda. With the help of the resulting solution, you can also get rid of simple contaminants (from complex or hard).

Lemon juice. It is enough to drop a few drops of this composition on the oxidized contact and wait a couple of minutes. After that, it is quite possible to clean almost shine.

Alcohol. For cleaning, you can use technical, medical or ammonia alcohol. A fairly effective means that can be used paired with others.

Cleaning paste "Asidol". It is intended for cleaning various household items "to shine". Therefore, it can be used for cleaning electrical contacts.

Sandpaper. It is better to use an fine-grained option in order not to damage the contacts.

The listed "folk" agents usually show good efficiency in the general case, if they interact with the pollution of the weak or average levels. Unfortunately, with multi-layer oxides, they can be copfer, as a rule, unable. Therefore, in difficult cases, it makes sense to take advantage of a professional. But in order to save money, you can first try to clean the contacts with undergraduate means, and if it does not help - use the factory cleaners listed above the factory cleaners.

The aerosol composition of the combined action. Removes metal oxides and fatty contaminants in a single process. Restores the electrical conductivity, blocks leakage currents. Does not damage parts from metals and plastics. - Cleans contaminated contacts - breaks and removes salts of oxides - reduces contact resistance - does not contain silicone using kontaktreiniger allows you to quickly and easily clear contacts from oxides and contaminants, saves time and improves the quality of electrical equipment service.

Application

Contacts Disable from the power source. The product spray to contacts and, depending on the level of contamination, leave about 5-10 minutes. Remove the dirt with a napkin, brush or compressed air. In the event of a product from entering lacquer or plastic surfaces, wipe them with a damp cloth. After cleaning, protect contacts using Elektronik-Spray (Art. 3110) or LM 40 Multi-Funktions-Spray (Art. 3390). Note: Connect to the power source 10 minutes after the cleaning is completed.

The modern chemical industry produces many drafts of the useful means of cleaning and protecting electrical contacts from corrosion and oxidation. But it is not necessary to discount the recipes of such cleaners, as they can also come in handy when working with those or other devices. This article describes several available chemical compounds for cleansing and protecting contacts.

Cleaning products for contacts can be relatively easy to prepare at home, and you do not need any exclusive materials.

After any of the cleaners given, you need to move the contacts to make up the composition of the all meta treated surface. You also need to wait about 15 minutes, in order to evaporate the solvent, after which it is necessary to wipe the contacts to remove dissolved contamination and excess solvent.

How to make liquid for cleaning electrical contacts Recipe first:

You need to mix in a glass jar of a substance observing the proportion:

250 ml of ammonia aqueous concentrated

750 ml of methanol (this substance is poisonous) or ethyl alcohol denatured by gasoline.

The mixture is stored in a well-closed glass container.

How to make liquid for cleaning electrical contacts Recipe Two:

It is necessary to dissolve 20-50 ml of vaseline (medical) oil in 950 ml of extraction gasoline. After you need to mix thoroughly and pour into a bottle.

Composition for cleaning silver contacts:

If it is possible to remove the contacts and put them into the solution, that's what you can use:

Contacts are first degreed by washing in trichloroethylene, ether or tetrachloromethane. Degreased contacts are immersed in a bath with a 5% solution of potassium cyanide (you will be very careful if it is poison !!!). Immersed in solution Contacts (no more than 1 min) It is recommended to move the part. If during this time does not dissolve the dark layer on silver contacts, it is necessary to immerse the parts into a new solution (the former is already saturated).

When pollution disappears, silver contact is necessary to rinse well in running water.

Note that after such removal silver is very subject to new oxidation! Therefore, your contacts must be placed in the composition of a concentrated (25%) pure ammonia solution, no more than 3 minutes (stir the composition continuously). Then it is necessary to rinse well with running water, or in ethyl alcohol, denatured by gasoline or ether and dry well.

After such operation, silver contacts will no longer be oxidized under the influence of the external environment.

Recipe defenses for contacts:

If you need to "put it up for a long time" electrical contacts, then do the following: In the porcelain cup, dissolve with weak heating 10 - 30 g of stearic acid and 980 ml of trichloroethylene (instead of trichloroethylene, tetrachloromethane or tetrachloroethylene can also be used.).

It is necessary to give a solution to stand and pour into a bottle with a good plug. This solution has a protective "preservative" action. Such a solution must be applied to carefully cleaned, skimmed and dry contacts with a homogeneous layer.

P.S.: I tried to visually show and describe not cunning tips. I hope that at least something will be useful to you. But this is not all that it is possible to invent, so dare, and look through the site

Let's remember the time when, in the era of the total deficit of the planned economy, the meager content of the consumer basket of a simple car owner accounted for not only the share of the inhabitants of the apartment, but sometimes the share of the steel horse, especially if urgent repairs in the house took place. Judge yourself: to flow in the cooling system were stopped by a mustard powder, whining threaded connections We were developed by acetic essence, and a piece of simple economic soap often and with due diligence and certain skills it was possible to tighten through the end-to-end damage to the gas tank. Obviously, similar to the then home-grown technologies, even the most insignificant repairs turned into a tedious and often unsuccessful event.

Another thing is in our time when the abundance of a variety of auto chemicals does not only inspire, but also causes a sense of some confusion even from the most experienced and matturists. With all this, the range of offered auto chemicals is growing, both on yeast, and in geometric progression. There are more and more new features to accelerate and facilitate the repair process without attracting professional professionals.

Auto chemistry agents are quite logical in their signs into two groups: branded drugs and little-known means. Moreover, the separation here does not mean the name of the specific brand of the manufacturer of auto chemicals, but by appointing the drugs themselves. Slightly below, we will carry out a small concise review of a little-known automotive chemistry to most readers.

In this review, we will look at some decent aerosol funds for the care of electrical wiring and electrical equipment of the car. The main habitat of these drugs is specialized shops and catalogs for professional repairmen. But this does not mean that these funds are too difficult to purchase, and they will be interesting to many.

Spray properties for wiring

Spray for electrical wiring should have in its composition, perfectly displacing moisture (for example, synthetic oils) and having a high dielectric constant, as well as certain additional components that contribute to the cleaning and protection of electrical contact materials from oxidation, providing excellent compatibility with elastomeric and polymeric materials.

Springs to care for electrical wiring perform the following main functions:
