The question of whether to wash the car immediately before going on a long trip, causes fierce debate among superstitious drivers and practitioners of the car service. Some believe that a clean car is an invitation to road dust and dirt, and a sure way to bring trouble or even an accident. Others insist that driving a dirty car is not only disrespectful to yourself, but also a potential safety hazard, as contaminated headlights and mirrors impair visibility.

The truth, as is often the case, lies in the middle, but requires detailed analysis in terms of physics, chemistry and even the psychological comfort of the driver. People's signsThe sensing systems passed down from generation to generation often have a rational basis, but in the past they were explained by mysticism rather than technical characteristics. For example, the ban on washing a car before the road could arise in those days when the roads were unpaved, and the quality of paintwork left much to be desired.

In today’s world, where the chemical industry offers aggressive reagents and navigation systems navigate routes through difficult weather conditions, the approach to car cleanliness must be considered. It is important to understand the difference between aesthetic washing and technical necessity. Driver.When traveling, you must take into account many factors: from the time of year to the state of anticorrosion protection of the body. Let’s look at this in detail, separating myths from reality.

There is a strong belief that says: if you wash your car in front of the road, wait for rain or dirt. This one superstitiousness It is based on the law of meanness and reverse causation. The logic is simple: if you washed your car and drove right away, and it rained or you drove into a puddle, the brightness of the contrast between the clean surface and the dirt that appeared creates the illusion of “punishment for cleanliness”. In fact, the weather is not affected by your actions with sponge and shampoo.

But there is a more rational grain in the old prohibitions. Before, when there was no quality wax-coating and ceramic, wet after washing the car in the cold season could be covered with a thin crust of ice or frozen dirt, which made it difficult to move and spoiled the body. It was also believed that a clean machine attracted the “evil eye” of envious or unkind spirits of the way. Today we can interpret the “evil eye” as the increased attention of traffic police to a neat vehicle, although this is more psychology than mysticism.

⚠️ Attention: Blindly following the signs about the ban on washing can lead to the fact that you will go to the highway with contaminated lighting devices, which is a traffic violation and increases the risk of accidents at night.

Some drivers believe that you can not wash away the “luck” accumulated over previous trips. This misconception has no technical basis. In contrast, a layer of dirt, consisting of a mixture of oils, reagents and abrasive dust, is an aggressive medium for paint coating (painting).LKKP). If you believe in energy, then a clean car, free from negative layers, should carry only positive to its owner.

Yeah, never wash before the trip.
No, mine is always for safety.
Only if the car is very dirty.
I don't care if I go.

Effect of dirt and reagents on the body in the way

From a technical point of view, ignoring pollution before a long trip can cause serious damage to the car. Road mud is not just an aesthetic defect, it is a complex chemical mixture. It includes the residues of fuel and lubricants, tire wear products, bitumen particles and, most dangerously, anti-icing reactants. When driving at high speeds, this mixture works like an abrasive.

The situation is especially critical in winter or in the off-season. Salt solution, getting on the body, begins the process of electrochemical corrosion. If the car was not pre-washed and treated with a protective composition, the salt penetrates into the microcracks of the varnish and begins to corrode the metal. Corrosion In such conditions, it develops many times faster than with static storage of a dirty car in the garage.

In addition, the sticky dirt can hide important defects. Cracks on the headlights, chips on the windshield or leakproof seals under a layer of dust may go unnoticed. On the way, under the influence of vibration and oncoming air flow, defects can develop into serious problems, up to depressurization of the cabin or failure of the optics.

💡

Use a contactless wash before your trip to remove the main layer of aggressive dirt, but be sure to dry the car with compressed air in hard-to-reach places so that the water does not freeze in locks and hinges.

It is also important to consider aerodynamics. A layer of dirt, especially on the front of the car, bumpers and mirrors, changes the streamlined body. While this impact is minimal for civil transport, at high speeds on the track, it can create additional vortices that will throw dirt even more intensely into the arches and on the rapids.

Risks for optics and traffic safety

Safety is the main argument in favor of maintaining the cleanliness of the car. Contaminated headlights and taillights are a direct threat to life. Even a slight decrease in optical light transmission due to a layer of dust or road film can be fatal in the dark or in fog conditions. The light beam becomes less intense and focuses less, which reduces the distance of visibility.

Particular attention should be paid to the side mirrors and windshield. Dirt on mirrors distorts view, creating “blind zones”. The driver may not notice the car going on overtaking or the pedestrian crossing the road. The windshield, covered with greasy coating, when moisture (rain, fog) enters, creates the effect of rainbow and glare from headlights, which causes rapid eye fatigue and reduces concentration.

Element of the car Type of pollution Implications of the journey Security risk
Windshield Fat film, insects. Glare, rainbow effect, poor outflow of water High (decreased view)
Headlamps for headlamps Dust, oxidation of plastic Decrease in brightness, scattering of light Critical (night)
Side mirrors Dirt, water from wheels Reflection distortion, blind spots High (rebuilding)
Rear lights Road dust, salt The car becomes less visible from the back. Medium (risk)

There is also a risk of mechanical damage. Large pebbles or pieces of dirt stuck in the tread of tires or arches, when driving at high speed can fly out and damage the LCP of your car or car following behind. Regular cleaning The wheel arches before the trip minimize this risk.

The Year: When is it Dangerous to Wash?

Seasonality plays a key role in making a washing decision. In winter, at low temperatures, a classic wash with plenty of water can cause moisture to freeze in door locks, a gas tank hatch and, worst of all, in the brake system if water hits the calipers. In such cases, the answer to the question “can I clean” becomes negative if cleaning means washing with water.

In frosty weather, it is recommended to use dry cleaning or express care using special aerosols that do not require washing off with water. If the washing is necessary (for example, wash off salt), then it should be carried out in a warm box followed by careful cleaning. blowing All the hidden cavities of compressed air. Going out into the cold immediately after washing is strictly not recommended.

⚠️ Warning: Attempting to wash the frozen wiper brushes or the ice crust on the body with hot water can lead to instant cracking of the glass or damage to the paint coating due to a sharp temperature drop.

In the summer, it's different. Here the main enemies are insects and poplar down. If you leave them on the body for a long time, especially under the influence of sunlight, they can “eat” in the varnish, leaving indelible traces. Acid secretions of insects can damage even the persistent LCP in a matter of hours. Therefore, in the summer, washing a car before a trip is not only possible, but also necessary to protect the body.

In spring and autumn, during the period of active use of reagents, washing is mandatory before putting the car for storage, but before the road it is also useful for removing the aggressive layer. However, it is important to consider the weather forecast: if a rainstorm with hail is promised, it may make sense to postpone a visit to the sink so as not to feel disappointed by the sight of a stained car, although technically it is not so scary.

Psychological aspect and driver comfort

Do not discount the psychological factor. Driving is a process that requires high concentration. Being in a clean, neat cabin, behind the wheel of a shining car, subconsciously sets up for disciplined driving and gives a sense of control over the situation. This phenomenon is sometimes called the “clean car effect”.

Dirty interior, a patched windshield, sticky steering wheel - all this creates background stress. The driver may not realize this explicitly, but his attention is dissipated in an attempt to compensate for the visual noise. Comfort. In a long trip, it directly affects fatigue. Clean windows provide better visibility, and the absence of unpleasant odors in the cabin (which are often masked by flavors in a dirty car) keeps the mind clear.

In addition, the neat appearance of the car often affects the attitude of other road users and road services employees. Psychologically, people are more likely to miss a tidy car in a dense stream or to be more condescending to a minor driver error than to the owner of the “dirty”, who, according to stereotypical thinking, may be less attentive to the technical state of his transport.

The link between purity and attention

Studies show that visual order in space (including the interior of the car) reduces cognitive load on the brain. Less distractions, more concentration on the road.

Protection technologies: how to keep clean

Modern autochemistry offers solutions that allow you to combine the desire to have a clean car and the fear of rapid loss of this condition. Use of the hydrophobicThe so-called "anti-rain" or ceramic compositions, creates a slippery layer on the surface of the body. Mud and water simply cannot catch on such a surface and are easily blown away by the oncoming airflow at speed.

Applying this coverage before a long trip is the best investment. Even if the car gets dirty, the nature of the contamination will be different: it will be easily washed off plaque, not ingrained dirt. In addition, the “anti-rain” on the windshield significantly improves the view in a shower, causing the drops to roll under the action of aerodynamics without the inclusion of wipers at low speeds.

It is also important to use the correct washing technique. Contact washing using dirty brushes can do more harm than good, leaving micro scratches that will accumulate dirt even more actively in the future. Preference is worth giving contactless washing followed by manual drying or washing self-service using soft chemistry.

Don't forget the hidden cavities. Before the trip, it makes sense to treat the bottom and arches with special protective compounds, if this has not been done previously. This will create an additional barrier between the aggressive environment of the road and the metal of your car.

💡

Using hydrophobic coatings before a trip not only keeps the car clean for longer, but also really improves safety by improving visibility in the rain and simplifying headlight cleaning.

Should I wash my car if it rains tomorrow?

In terms of physics, yes. Mud combined with rain turns into abrasive porridge that scratches the varnish. A clean body with a hydrophobic coating will self-clean in the water flow faster than a dirty one. In addition, clean headlights are critical in cloudy weather.

How to remove insects from headlights before leaving?

Use special sprays-cleaners insects (Bug Remover). Apply the remedy, wait 2-3 minutes (not allowing it to dry), and rinse with water or wipe with a soft microfiber. Do not rub dry insects with a cloth - scratch the plastic.

Is it true that birds are more likely to sit on a clean car?

There is no scientific evidence for this. Birds are attracted by parking under trees, the presence of food nearby or the reflection of the sky in a glossy surface. The color of the car (especially red or white) can make a bigger difference to birds than its cleanliness. However, on a smooth, clean surface, it is easier to remove the droppings until it dries.

Do I need to wash the disks before traveling?

I will. Brake dust on the discs is very aggressive and when heated during movement can damage the lacquer coating of the discs. Also, clean drives are easier to wash on the way back, removing fresh road dirt.

What to do if the locks freeze after washing?

Use a lock defrosting device or an alcohol-containing liquid. Do not pour hot water – it will freeze even faster. For prevention, always purify locks and seals with compressed air after washing in winter and lubricate with silicone.
