An easy way to clean various types of dirt from any surface is dry ice cleaning - cryoblasting. Blasting devices are considered abrasive-blowing devices, during which air under high pressure is supplied to the surface for cleaning. The main substance is ice granules in crystalline form. It is obtained from carbonic acid, which does not have a water base, which is why this technology is called cryogenic blasting.
What it is?
Cryogenic blasting has been popular for over 25 years. Technologically, the procedure is similar to sandblasting of parts. In the first version of cryoblasting, cleansing is performed with dry ice granules, which, when they hit the surface, are converted into a gaseous state. In the second case, cleaning is carried out with small hard particles, which exhibit a grinding effect and spoil the processing plane. The granules are frozen to -80 degrees Celsius. Dirt and stains are broken down and removed from the surface. Frozen granules undergo evaporation and do not harm the thinnest and most fragile parts.
A clean, tidy car: something about washing your car at special car washes
For many car enthusiasts, the topic of cleaning a car at a car wash is constantly relevant. It would seem that such a simple process, and there is nothing special to say here. However, so many contradictory words have already been said and various videos have been made on the topic of car washing that many are beginning to doubt whether they are doing the right thing. To understand how to wash, when, and how often, you need to familiarize yourself with all aspects of this simple process, and draw the right conclusions for yourself.
Why wash your car at a car wash?
Before moving directly to car washes, it should be said that washing a car at home has also attracted quite a lot of conflicting thoughts. However, they are in many ways similar to the topic under consideration, so they are not worth mentioning separately. For those who want to become more familiar with this issue, there are many videos on this topic on the Internet.
A very simple question that still causes difficulties for some. Indeed, why wash your car at a car wash if you can save a lot of money by doing it at home. The answer to this question is as simple as the question.
Firstly, a specialized car wash has equipment that can much more effectively clean the car of stubborn dirt. This is especially true for hard-to-reach places such as the bottom, arches and engine compartment. Professional equipment allows you to effortlessly cope with even those contaminants that are beyond the power of the most avid car enthusiast.
Secondly, specialized car washes are staffed by experienced personnel. Workers who work at a car wash wash so many cars in one working day that they certainly accumulate a huge store of knowledge about how to do it correctly. They also often listen to the special wishes of car enthusiasts, which each have their own. This makes it possible to apply the experience gained on each subsequent machine, constantly improving the quality of work.
In addition to all this, not every car enthusiast can afford to buy quality car care products. And not because they are quite expensive. But because they simply don’t know which is the best and which is not worth buying. Professionals are more familiar with these nuances, again due to their experience.
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.
How often should you wash your car at a car wash?
Another question that misleads many, despite its simplicity. There are only two answers to this. Is the car dirty? You need to wash, and not pay attention to how many hours or days have passed since the last wash.
If you delve deeper into this issue, you can come across opinions that if you wash your car too often, its paintwork will quickly come to an end. In part, there is some truth here. However, this truth most likely refers to outdated concepts about car washing. Nowadays, modern equipment is used for washing cars, which does not particularly affect the paint of the car.
The same applies to body care chemicals. Modern chemical formulas are much different from those that existed before. The chemical carefully removes dirt and other deposits from the car. But she doesn’t touch the paint. Naturally, all this applies only to those car washes where they choose the right chemicals and use the equipment correctly. More about this.
How to choose the right car wash?
To achieve the maximum effect from visiting a car wash, you need to choose it correctly. This is quite easy to do. The first thing you should do is ask your friends and acquaintances. Listen to their opinions on this or that issue about each car wash they visited. Preference should be given to those services that your friends have visited repeatedly. Repeated visits to the same car wash says a lot.
The same can be done directly at the car wash. If there is a long queue and you need to sign up in advance, then this indicates regular customers who trust the service. You can also watch the car wash from the side. Pay attention to what cars drive there. Expensive foreign cars? Cheap and rusty scrap metal piles? Draw conclusions.
And finally, you will have the opportunity to verify the quality of the wash yourself. No one will forbid you to stop washing if you see that your car is being treated like a tin can. At professional car washes, the workers treat someone else's car as if it were their own. You can verify this by at least watching several videos on this topic.
The nuances of washing a car in winter
Washing a car in winter is a separate issue that requires a few words. There are also a lot of opinions and disagreements here. However, most are inclined to the following general advice:
- It is necessary to wash your car in winter as often as in summer;
- Do not use hot water for washing;
- Before washing, you should take care of the locks and seals. If water gets there, and it does, you may not be able to get into your car in the morning;
- After washing, be sure to wipe the body dry. Some car washes use compressed air to dry the car, and such services should be given priority.
In winter, washing your car is simply necessary, since the road is full of substances that have a detrimental effect on the paintwork. And these substances are much more aggressive than the cheapest car wash shampoo.
And it is in winter that it is important to visit professional car washes, since washing a car at home in the cold is a rather difficult task that not everyone can do.
What equipment is needed?
A special feature of the method is the mobility of the equipment, which supplies dry ice granules under high pressure. Small size cleaning unit. It consists of wheels and handles for comfortable transportation, the weight is 30-100 kilograms. The units operate from ready-made ice, which is pre-immersed in a special special container.
Many devices are powered by compressed air; certain models must be connected to an electrical outlet. In each case, together with the design, you should purchase a high-quality compressor that meets the established requirements. The capacity of small machines is 10-30 kilograms of ready-made ice; in industrial ones it is possible to use up to 200 kg. For an ordinary wash, the lowest pressure of 6-9 bar is sufficient; for difficult mud deposits, you need to use the full force of 15-19 bar. To support the washer, manufacturers provide many different attachments that improve the supply of granules and make it possible to reach remote areas.
A few words about the main thing
The engine needs to be washed, and there are a number of good reasons for this:
Definition
As practice shows, for the query “dry engine washing”, search engines return articles telling about technologies for washing the engine compartment that are different in nature, which indicates a certain confusion present in this area.
Chemical washing
Oddly enough, the dry cleaning method is sometimes described as washing using foam engine cleaners. To use you need:
As you yourself understand, this method of cleaning the engine compartment will have something in common with a dry wash only if you blow off the active foam with air pressure, and not wash it off with water. Unfortunately, this method is not very effective, since the air will only disperse dirt from the front surfaces, leaving a lot of deposits in hidden cavities.
Advantages and disadvantages
This cleaning method copes with any dirt on all surfaces.
The key advantages of cleaning the surface with this method, identified by users, are:
- Productive cleaning method. Eliminates all kinds of blockages and dirt stains, including complex, old and difficult to remove.
- Ease of use. There is no need to dismantle complex equipment and its elements.
- Cleaning hard-to-reach areas.
- Soft cleaning. Cryoblasting is considered the most gentle method in relation to the surface of the equipment.
- Multi-purpose use. Dry ice cleaning can be used on a variety of surfaces.
- High speed. Cleaning occurs several times faster than usual.
- Antibacterial method. Dry ice, when exposed to cold temperatures, instantly kills fungus and dangerous bacteria.
- Protection. It protects against liquid penetration, therefore this method can be applied to electrical equipment.
The main disadvantage is the lack of stable use without purchasing the necessary special equipment. It is also not always possible to do without disassembling the equipment into separate elements for easier cleaning. For complete safety, it is recommended to turn off the power supply to the cleaning object when carrying out cleaning procedures.
This is a process in which new generation special technological equipment is used. Therefore, it is impossible to carry out the procedure with your own hands; cleaning with dry ice can only be performed by a special service.
Is it possible to make the device yourself?
To assemble the device, you need components that cannot be made with your own hands. Buying ready-made parts violates the very concept of do-it-yourself production. And the final price will be rounded up to such a figure that purchasing ready-made equipment will be more economical.

Dry steam
It is steam washing that is most often passed off as dry engine washing, which is a mistake. A powerful jet of steam is used to remove oily, bitumen deposits. To understand the technique, the following characteristics are important:
The dirt is supposed to initially dissolve and then be blown away by the steam pressure. Adherents of steam washing claim that cleaning the engine with this method relieves car owners from the main disadvantages inherent in high-pressure washers:
Is the steam really dry?
Of the entire spectrum listed above, we are interested in the point about the absence of moisture getting to the contacts. It is this risk that discourages many drivers from the idea of washing the engine. There are often cases when, after using high-pressure washers, engines do not start, stall, or operate intermittently in certain modes; Automatic transmission control units are not immune to this problem.
The concept of dry steam really exists. In the world of physical phenomena, this term refers to steam heated to a temperature exceeding the boiling point at a given pressure. As you know, if you heat water to 100º C, a certain amount of steam is formed, which will fill the volume free of water. If we continue to heat steam in a closed space, we will get dry steam. In contrast to regular steam, dry steam has an important feature:
Superheated steam is used in various cycles of heat engines to increase efficiency. The temperature of superheated steam can reach 400-450ºС. And now we invite you to carefully watch the video in which a dry engine is washed with steam. As we can see, condensation inevitably forms on the walls, which, as in the case of water, can damage the contacts of electrical circuits. We agree that in the case of steam washing there will be less moisture, but it will still be there.
Cleaning technology
The dry ice cleansing technique is considered multi-level. The first process is cryoeffect. The crystals at the exit from the nozzle have a temperature of -80 degrees Celsius, so the clogged surface becomes fragile and is simply cleaned of small dirt spots. The next stage is kinetic. The granules reach the speed of sound when leaving the nozzle. A lot of kinetic energy, which is released when touching a fragile plane of contamination, will form cracks of minimal size, through which crystals fall. The third stage is sublimation. Dry ice, getting into the middle of the blockage, instantly evaporates. When changing from a solid state to a gas, its size increases 600 times, creating an explosive result that tears apart the dirt inside. Low-temperature blasting technology makes it possible to easily remove various contaminants.
