How to properly wash a car with a Karcher - instructions and tricks

Not every driver wants to pay huge amounts of money every month for car wash services. Of course, if you live in a huge high-rise building and have a parking space of several square meters, there is no special choice. But if you have a garage or cottage, you can easily get rid of car washing fees. It is enough to purchase a mini-wash, for example, Kärcher, and learn how to use it correctly.

In order to properly wash your car with Karcher, you need not only to obtain information on the operating features of your particular device, but also to purchase the necessary automotive chemicals. It is highly desirable that these products are recommended by the washer manufacturer.

Introduction

A high-pressure washer will help you clean any surface to a shine - be it a car, a sidewalk or, for example, a carpet. The water pressure it creates allows you to wash away dirt even from the narrowest crevices, which is impossible to achieve by hand washing.

These machines differ in pressure and water consumption, type of pump and engine, as well as equipment.

There are professional and household sinks. Since the article is mainly aimed at a wide range of readers who buy equipment for personal use, we will further discuss the choice of household sinks. Professionals usually know what to buy.

And I also want to note that household units are designed for washing cars or minibuses. That is, those vehicles whose body surface is smooth. For trucks that have various cracks where dirt gets clogged, I recommend purchasing at least semi-professional devices with a pressure of 150 atm or more.

After such a digression, I will continue my story.

Instructions for washing a car with Karcher

The presence of hundreds of would-be advisers on the Internet has become a real problem. In every second article about “proper” car washing, you can read information that you need to wipe dry dirt with a rag or other useful advice that will help you quickly decide to repaint the entire car. If you wash your car with Karcher, then there should be no contact actions. This is a contactless car wash; the machine will do all the work for you.

If the car is too dirty, you must first remove the dirt from it using water pressure. And here again there is a lot of advice that active foam is applied to the body only in dry form. This is a myth - it is in combination with water that the foam will work most effectively. So, the process of washing a car with Karcher is as follows:

• remove dust and dirt from the body using high water pressure from the device;
• wait a few minutes until most of the water drains;
• apply the selected element of automotive chemicals (shampoo, foam, etc.) to the body;
• The body must be completely covered with this solution, including the glass;
• give the active elements of chemistry a few minutes to work;
• thoroughly rinse off the foam using high water pressure;
• If necessary, wipe the car with a soft cloth or let it dry.

While performing all these procedures, do not forget about the wheel arches, the wheels themselves, the lower part of the sills and bumpers. These places often go unnoticed during self-washing, and the result of the entire process does not please the owner. Car shampoo also requires special choice.

If you buy cheap automotive chemicals, the washing result will be unexpectedly bad. Official chemistry from Karcher is also not universal and is not suitable for all types of paintwork. Manufacturers often make recommendations regarding the chemicals used for care. These are the recommendations that should be followed.

How to choose a high pressure washer for your car. Accessories

What additional accessories do I need to purchase for my high pressure washer? Many sinks are already equipped with all the necessary accessories. These can be replaceable nozzles or the entire barrel with nozzle, brushes and containers for detergent. Also, if the kit does not include the necessary accessories, you can purchase them separately. They help you perform certain specific tasks faster and easier.

Car wash brush. It is an attachment to a spray gun and helps remove thin road film, as well as stubborn dirt on the body and wheels.

Additional nozzles or lances (barrel with nozzle). You can purchase an additional barrel with a nozzle that allows you to change the spray direction for washing the bottom and arches. There are also attachments that allow you to effectively wash other surfaces in addition to your car. For example, the Dirtblaster nozzle sprays water with a stream of small diameter, while rotating at high speed to increase the surface of impact.

• There are a wide range of specialty chemicals that can be used with a pressure washer to improve cleaning performance. Pressure washers use one or two ways to add detergent. Basic budget sinks usually have a detergent bottle (foam nozzle) that can be attached to the gun. The venturi effect is used to force the product out of the bottle as the water passes through the gun. Other models have an integrated reservoir. You can read more about applying foam to a car in the article “how to wash with a high pressure washer.”
• Hose with filter for connecting to a tank filled with water. Allows you to use rainwater from a barrel.
• In addition to the sink, you can purchase a good extension cord that can withstand the load of a working sink. When using an extension cord, the cable must be completely unwound.

Is it possible to “kill” a motor by washing?

If the high-pressure washing technology is violated, then:

• the car will not start;
• the engine will start, but immediately stall;
• some electrical appliances will stop working;
• unstable engine operation is observed;
• there are dips when pressing the gas;
• no traction.

The main troubles will affect the electronics , since the mechanical part is protected from water penetration. Some signs will appear only after a certain period of time, for example, this concerns the oxidation of contacts.

If most problems in the operation of an internal combustion engine can be eliminated by getting water on the spark plug wells by drying the contacts of the distributor, then if the electronic control unit fails, you will have to invest a lot of money in its repair. Therefore, before washing the car, you should carefully prepare it.

Mistakes in using a mini-washer

The high-pressure cleaner is easy to use, however, owners make many mistakes when trying to wash their vehicle.

Some of them are worth talking about separately:

1. If you have little experience using a mini-wash, then do not take the initiative to clean someone else’s car. This is fraught with unpleasant consequences.
2. We wash the car using moderate pressure. Otherwise, the putty may fall off the body.
3. When buying cleaning products, you should not give preference to those that form strong foam. There were cases when she ate the top paint layer.
4. Do not make sudden movements when using the washing machine.
5. Surface cleaning agents should be applied evenly.
6. Carefully direct the stream at doorways and other body gaps so that the liquid does not leak into the car interior.
7. Try to avoid the radiator grille.

The direction of water flow does not really matter: whether it will be from bottom to top or vice versa. In the latter case, the rinsing process occurs faster.

The main mistakes that beginners make when mastering a mini-wash were presented here. To get a complete overview, it is recommended to watch the video, which clearly shows how to properly wash a car with Karcher.

So, let's summarize. If a car owner decides to save the family budget by regularly visiting private car washes and buys a high-pressure washer for personal use, then the first thing you should do is thoroughly read the operating instructions for the device. Otherwise, washing at home will ruin the appearance of the car. Read, listen and put into practice only proven advice. They will help keep the surface of the vehicle in its original appearance.

Safety precautions

Before washing your car with Karcher, you need to study the safety rules . Water flies out of the nozzle under very high pressure, so if the device is used incorrectly, this can lead to dire consequences. Particular care should be taken when using nozzles that produce a pinpoint and narrow stream of water.

You cannot come closer than 15-30 cm; the surface begins to be processed from a distance of 60 cm. It is forbidden to use the sink while standing on a hill. When the trigger is pulled, there may be kickback, causing you to fall.

It is safer for the operator and the paintwork to spray with a wide spray pattern. It takes longer, but the risk of damage is much lower. Do not use a contactless car wash near a power line or point the nozzle with pressurized water at people or animals.

Selecting nozzles and brushes for a high pressure washer

Initially, high-pressure washers were intended for cleaning surfaces in a non-contact way - that is, simply with a stream of water supplied with high pressure. After sinks became available to a wide range of users, manufacturers, in order to increase their capabilities, began to equip washing guns with a variety of attachments. Some of them change the shape of the water jet, while others are additionally equipped with brushes with bristles of various lengths and hardness - this allows you to combine the effectiveness of non-contact cleaning with the ability to remove dirt by contact or foam detergents.

Bristle hardness

Bristles are usually used in two types of hardness - soft bristles, for smooth surfaces, and hard bristles, which are convenient for cleaning dirt from places with a rough surface. Hard brushes are also used for cleaning shovels and similar garden tools that there is no danger of scratching. The location of the brush can be arbitrary - along the handle or across it, like a mop.

How to properly wash a car under the hood

Before you start washing the engine, you need to remove decorative and protective screens, plastic elements, and disconnect the wiring . Cover the tanks and body parts with inscriptions and plates; waterproof material is suitable for this.

Close with polyethylene and tape:

• electrical equipment parts;
• terminals;
• connectors;
• air intakes.

It is advisable to remove the battery . You cannot start washing the engine while it is still hot, the chemical composition will evaporate quickly and the result will not be visible. The engine temperature should be 40-50 degrees.

Before the procedure, be sure to remove dry leaves so that they do not fall into the drainage holes. Coat the motor with a special compound and wait the prescribed time. There is no need to apply foam liquid liberally; it will take a long time to rinse off, which poses a danger to electrical wiring. The engine must be flushed gently so as not to damage plastic and rubber parts and wiring. It is better to wash the engine in warm weather. In cold weather, water may remain on the moving parts, this will negatively affect the condition and operation of the engine. Drying is necessary after washing .

A high pressure washer is also used to wash the engine.

Operating instructions for the Kärcher mini-washer

There is an opinion among Internet users that before you start using a mini-wash, you will first need to clean the entire surface of the body from dirt with a dry cloth. Such judgments are made by ignorant people. Don't make these mistakes. Karcher is a contactless way to wash your car.

Shampoo dissolved in water is applied to a dry, dirty or dusty surface of the car.

There is no need to do any preliminary meaningless manipulations. If the body is wet, the cleaning agent will not have time to react with the dirt, but will roll to the ground.

So, the rules for operating a car wash require the following actions:

1. Prepare the vehicle for cleaning. It should be dry.
2. Apply auto chemicals from bottom to top. At this stage, drivers often make the mistake of spraying it from top to bottom. It is wrong to do this, because the dirt, reacting with the product, actively swells and creates a barrier, which helps prevent the shampoo from rolling off the body.
3. You should start applying special substances from the rear of the car in a clockwise direction. Leave the roof and hood for later.
4. It is also necessary to wash the car from the bottom up due to considerations of the time the product remains on the surface of the body.
5. At the end of the process, it is recommended to rinse the car with clean water so that no trace of detergent remains.
6. To achieve perfect results, use a faux leather cloth when wiping your washed car dry.

Advantages of a contactless car washing method

When using this modern device, materials and compositions that negatively affect the properties of varnish and paint and contribute to corrosion are not used. The car surface remains bright and shiny. The touchless wash takes about 15 minutes.

Thanks to the new technique, it is possible to remove dirt both from the surface of the body and from hard-to-reach places :

• bottoms;
• engine compartment area;
• spaces under the seats;
• wings;
• wheel rims.

Another plus is the affordable price .

A touchless car wash can thoroughly clean your entire car.

It is difficult to imagine any modern cleaning or washing process without the use of such a convenient and practical device as a high-pressure washer. It is easy to use, affordable, and effective on large surfaces. By purchasing a mini-wash for private use, you get a real assistant who can facilitate any work related to cleaning the house and the surrounding area, cleaning the territory, washing a car, walls, roofs, facades, garden equipment and agricultural implements.

Choosing a mini-wash is a process that requires special scrupulousness and seriousness. It is no secret that German-made Karcher high-pressure washers are the most popular among consumers. They are so popular and widespread that many buyers call any washing unit from another company Karcher. A real Karcher is distinguished by its versatility and reliability. Such a machine is suitable for performing almost any task, so the demand for this equipment is growing every day.

The reason for its popularity is that Karcher specialists were the first in Europe to produce high-pressure washers, and therefore have extensive experience in developing new models. Over decades of productive work, they managed to study this issue thoroughly, introduce several patented technologies, and select ideal materials for the washing mechanism.

How to make the right choice of mini-wash

Karcher has several classes of sinks. Each model has a type designation: – K2, K3, K4, K5, etc. Also on the packaging of each sink there is a diagrammatic illustration of what can be washed with it. The classes differ from each other in performance, power, price, and, most importantly, the material from which the pump is made.

We will help you understand the main types of mini-washes from the renowned German manufacturer in order to find out their features and performance characteristics, because these indicators determine performance and determine their purpose.

There is a common opinion among users that they need to be guided by size. The small one washes small objects, the medium one washes, respectively, medium-sized ones (including a small and not very dirty car). And the big one - everything of size, including trucks and trucks, tractors and combines.

There is a grain of truth in this statement. But it’s better to look not at the size of the washing machine, but at its technical characteristics.

1. Entry-level mini-washers K2 and K3 are characterized by a low price and small body parameters. Their advantage is light weight, ease of storage and transportation. They are compact and fit in the trunk. But they don't wash well. K2 are suitable for garden equipment, benches, borders, bicycles. As a rule, they are purchased for rare and short-term work on occasional cleaning of small areas. K3 will wash both a motorcycle and even a car, but not too dirty. The pressure in such models does not exceed 100-110 bar. Classes K4 and K5 are the most optimal and popular among users. These devices are practical, easy to use, and designed to perform a wide range of tasks. They have a long working life and a durable aluminum pump. The outlet pressure can reach 120-140 bar, it is possible to work with any source of water, it can be connected to a tap or to an artificial reservoir, a water tank, or a barrel. This is the most optimal option for a mini-wash, including high technical characteristics and an affordable price. It is also worth noting that this class is equipped with:

• Quick connect system;
• forced cooling of mechanisms, which promotes long-term operation;
• hoses included, K-4 – 6 m, K-5 – 9 meters.

2. There are also high-class Karcher industrial units K6 and K7. They can work without interruption for cooling, that is, constantly on. This feature is important in large service stations, when washing large areas in enterprises. The speed and performance of such machines are worthy of respect; no other manufacturer can compare with them. The devices are large, heavy, and equipped with wheels for transportation. For a home there is no point in buying such a unit with such power, but for a business it is just right.

What is needed for a quality wash?

In order to choose the right model that will best satisfy your needs, you need to familiarize yourself with the features of each, the range of its operation, the rated power and the capabilities that it provides to the mechanism.

You will be able to use Karcher correctly only when the technical characteristics of the washing unit perfectly match the future volume of work.

The tips located on the box of each unit will help with this - the areas of application of the model that it can cope with are drawn here. Instructions for use of each device are included in the box; you should also read them carefully. The standard package of Kärcher miniwashers has everything necessary for the device to fully operate, but some models do not have a low-pressure hose. Sometimes it can be replaced with a garden hose of a suitable diameter.

The cleaning performance is affected by the material of the piston and pump. Karcher always has a steel piston, and regarding the design of the pump, its material comes in different types:

• Fiberglass. The strength is not bad, but it does not tolerate heavy loads. Installed in the lowest class, K2 and K3.
• Die-cast aluminum. Surprisingly durable and light at the same time. Does not rust. Resistant to deformation and loads. Used in classes K4, K5.
• Brass alloy. Combination of copper and inca. It is considered an “eternal” material that does not change its appearance for decades.

High-quality washing is also determined by the detergent; it must be special, designed for high-pressure washing.

Washing stages

The first stage of working with a mini-wash in a home or industrial environment is to clearly determine the source of water: a stationary water supply or a prepared container.

Connecting a Karcher sink to a water supply is the most popular method of using it. To enable it you need:

1. You need to attach a filter and fitting to the supply pipe. A filter is not a prerequisite, but water, even from a tap, is never absolutely clean. Therefore, it is better to protect the unit from damage.
2. Using an adapter, attach the hose. Ideally, the adapter should be quick-clamping, keyless, and even with an aqua-stop to stop the reverse flow of water.
3. On the other side, the hose is connected to a water tap. Here’s a simple way to connect to a centralized water supply. Before connecting the Karcher to a barrel or natural source, we do the same thing, only we hook the hose not to the tap, but lower it into a container. And we suck it in a little (like gasoline from a canister). It is very convenient when an outlet with a fitting is cut into a barrel or tank. Then the hose can be attached to it.
4. We check the clutch points, the possibility of water leakage and troubleshoot problems
5. Apply detergent to the contaminated surface. To carry out a touchless wash, detergent is applied to dry dirt.
6. After rinsing, the surface should be wiped if necessary.
7. It is worth noting that when using contaminated water, it is still necessary to resort to the use of special filters to purify the liquid. If we pull from a barrel, then the filter must also have a check valve (so that water does not leak out).

Pros and cons of self-service car wash

Types of specialized car washes

Before washing your car at a professional car wash, you should decide for yourself what type of service you prefer. All sinks can be divided into two types. Some will be able to provide you with high-quality equipment, highly effective chemicals and an experienced cleaner. Others provide the same thing, only without a washer.

Usually, if a car enthusiast has a limited budget or great confidence in his abilities, then he chooses the second type of car wash. Here you can, for little money, clean your car of dirt yourself and put it in order exactly the way the owner likes it.

The disadvantage of such a car wash is obvious - inexperience and lack of knowledge cannot guarantee the same quality that is possible at a car wash with staff.

Washing a car with Karcher: tricks and secrets

When washing with Karcher, special car shampoos , which are concentrated formulations. They are diluted in the proportions indicated on the packaging. Do not direct the jet directly at the gaps between the panels; water may penetrate into the interior. Headlights and glass are washed with less pressure and a wider torch. It is not always possible to remove dirt particles embedded in the paint with a high-pressure apparatus. You can remove it using special clay for cleaning the body. a rotating nozzle (tornado) to wash your car . It can easily damage the paintwork because it is very aggressive. To ensure that no streaks remain, wipe the surface dry with a clean, dry cloth.
