A trip along a freshly laid highway or parking at a facility under construction often turns into an unpleasant surprise - the car body is covered with black sticky spots. This is bitumen, which, drying, turns into a hard crust, capable not only to spoil the appearance, but also to damage the paintwork with an inept cleaning attempt. Car owners often panic, starting to rub stains with rags or trying to scrape them off with their nails, which is categorically impossible to do.
There is. Best Removal of BitumenIt dissolves the resin in minutes without affecting the paint. However, the market of autochemistry is saturated with offers, and it is difficult to choose a truly effective product among dozens of bottles. In this article, we’ll break down the chemical composition of cleaners, compare popular brands, and find out why some methods of “grandfather” cleaning can cost you expensive repainting.
It is important to understand that bitumen is a complex hydrocarbon and requires specific solvents to dissolve it. The usual water or shampoo is powerless. The right chemistry It allows you to soften the structure of the pollution, turning a solid mass into a liquid emulsion, which is easy to wash off with a jet of water.
Why bitumen is dangerous for the body of the car
Bitumen spots are not just an aesthetic defect. When heated in the sun, the resin softens and can penetrate into the microcracks of the varnish, and over time, oxidizing under the influence of ultraviolet light, it hardens so much that its removal becomes a difficult technical task. If left untreated for a long time, they can cause corrosion of the metal under the paint layer.
Mechanical removal without the use of chemistry often results in scratches. Trying to wipe the stain with a sponge, you rub abrasive dust particles contained in the bitumen itself into a paint coating. As a result, instead of a black spot, you get a matte area with a network of micro scratches that will require polishing.
Especially dangerous is the effect of bitumen on plastic body elements and rubber seals. Aggressive components of road tar can cause deformation of the plastic or its turbidity. Timely cleaning special compositions - the only way to maintain the factory condition of the LCP and avoid expensive restoration work.
It is worth noting that some types of bitumen contain active chemical compounds that, if in prolonged contact, can react with components of automotive paint, especially if it is of poor quality or has already been restored before.
⚠️ Warning: Never try to pick up frozen bitumen with a knife, blade, or hard brush. This is guaranteed to damage the varnish, which will then have to be rebuilt with polishing or painting.
Criteria for Choosing an Effective Cleaner
Choosing. Best Removal of BitumenIt is necessary to pay attention not only to the price, but also to the chemical formula of the product. The basis of a quality cleaner is a mixture of organic solvents that do not aggressively affect automotive enamel. It is important that the composition is absent of strong acids or alkalis.
The form of release also plays a role. Aerosol cylinders are convenient for spot application and work with hard-to-reach places, as they create pressure that helps to penetrate the layer of pollution. Bottled liquids are more economical for processing large areas, but require application to rags or spraying pulverises.
- 🧪 Safety for LCPs: The product should be labeled as safe for all types of automotive paints, including acrylic and metallic.
- 🛡️ Protective additives: The presence of components that create a temporary protective film will prevent the dirt from sticking again immediately after washing.
- 👃 Smell and toxicity: Less toxic compounds have a less pungent odor, which is important when working in a garage or without supply ventilation.
When buying, you should pay attention to the manufacturer's recommendations regarding the exposure time. Fast-acting products work in 1-2 minutes, but can be more aggressive. The softer formulations require 5-10 minutes to react, but guarantee complete safety for rubber and plastic.
Be sure to check the production date. Solvents tend to evaporate or change their properties during long-term storage, especially if the packaging was leaky. Fresh produce It always works more efficiently and predictably.
Overview of popular brands and means
The autochemistry market offers a wide range of solutions, from professional chemistry to budget options for the mass market. The leaders of the segment are traditionally considered brands specializing in child-raising, such as Kerry, Grass, Liqui Moly and Runway. Each of these tools has its own characteristics.
Products Kerry The article KR-935 is famous for its accessibility and a good balance between bitumen aggressiveness and paint safety. It is a great choice for regular use. Resources from Grass (e.g., Grass Bitum Cleaner) are often used by professionals in washing due to the high concentration of active substances.
German brands such as Liqui Moly Teer EntfernerThey are often more expensive, but offer high quality cleaning and the presence of protective oils in the composition, which reduces the risk of overdrying rubber bands. Budgetary options like Runway or Hi-Gear They also show good results, but may require more consumption on heavily polluted sites.
| Brand | Type of packaging | Time of action | Features |
|---|---|---|---|
| Kerry KR-935 | Aerosol 520 ml | 2-5 minutes | Good penetrating ability, affordable price |
| Grass Bitum Cleaner | Trigger 700ml | 1-3 minutes | Professional concentration, economical expenditure |
| Liqui Moly Teer Entferner | Aerosol 500 ml | 3-5 minutes | Contains protective oils, safe for plastic |
| Runway Bitum Cleaner | aerosol 400 ml | 3-7 minutes | Budget option, requires washing with water |
When choosing, you should focus on the scope of work. For the rare cleaning of the thresholds after a trip to the south, one cylinder is enough. If you plan to process the entire body or regular use, it is more profitable to purchase concentrates or large volumes in trigger bottles.
Can I use a cleaner on matte paint?
Matte paint coatings require special care. Most aggressive solvents can leave glossy spots on the matte surface. Before using any means on a matte body, be sure to test on an inconspicuous area or use specialized chemistry marked Safe for Matte Paint.
Technology of proper removal of bitumen spots
The cleaning process requires a certain sequence of actions to achieve an ideal result. First, the car must be washed with a conventional shampoo to remove surface dust and dirt. If you rub bitumen on an unwashed car, the sand will scratch the body.
After washing the body must be dry. Water can create a film that will reduce the efficiency of the cleaner. Apply the product to the surface or on the microfiber, let it act specified by the manufacturer time. Do not let the composition dry out in the sun - this can lead to the formation of difficult divorces.
☑️ Body cleaning algorithm
To remove softened bitumen, use a soft microfiber. The movements should be smooth, without strong pressure. If the stain does not move away the first time, repeat the procedure for applying the cleaner, but do not rub it with all your might. After removing all the stains, be sure to wash away the residues of chemistry with plenty of water.
The final stage is recommended to apply protective wax or polyrene. Bitumen cleaners often degrease the surface, leaving the varnish vulnerable. Protective layer It will help restore hydrophobic properties and facilitate future washings.
⚠️ Warning: Avoid getting bitumen cleaner on rubber seals of doors and windows, as well as on unpainted plastic. Prolonged contact can cause them to swell or change color.
Folk methods: kerosene, white spirit and diesel
In search of savings, many motorists turn to “people’s” means, such as kerosene, white spirit, diesel fuel or even gasoline. These substances are indeed solvents and are able to remove bitumen, but their use carries serious risks for LCPs.
Gasoline and kerosene are very aggressive and can dissolve not only bitumen but also the varnish itself, especially if it is old or low-quality. In addition, they greatly degrease the surface, leaving behind greasy rainbow spots that are difficult to remove. White Spirit It is considered a more gentle option, but its frequent use is not recommended.
The main problem of folk methods is the lack of special additives that protect paint and plastic. Professional chemistry contains corrosion inhibitors and softeners that minimize the harmful effects of the solvent on the body. Using a diesel fuel, you risk getting a matte spot instead of a black one.
If the use of alternative remedies is inevitable, apply them only on the rags, and do not splash on the body, and immediately thoroughly wash off with water and shampoo. However, given the low cost of specialized aerosols, the savings in this case do not justify the potential damage.
Before using any, even the safest-looking means, test on an inconspicuous area of the body (for example, inside the doorway) to make sure that the paint does not react.
Common mistakes and precautions
One of the most common mistakes is ignoring the instructions for the shutter time. Users either flush the product too early, preventing it from dissolving the resin, or over-contain it, allowing the solvent to begin attacking the paint layer. The optimal exposure time is usually 1 to 5 minutes, but not more than 10.
Another mistake is working on a hot body under direct sunlight. Heating accelerates the evaporation of the solvent, because of which it does not have time to react with bitumen, but only spreads, soiling clean areas. In addition, on hot metal, chemistry can behave unpredictably.
- ❌ Use of rigid sponges: The abrasive side of the dish sponge is guaranteed to leave scratches on the varnish.
- ❌ Lack of flushing: The cleaner left on the body continues to work and can damage the beauty when heated in the sun.
- ❌ Neglecting PPE: Pairs of solvents are harmful to breathing, and getting fluid into the eyes is dangerous, so it is better to carry out work in gloves and a mask.
It is also important to keep fire safety in mind. Most bitumen cleaners are flammable. Do not smoke near an open balloon and the surface to be treated. Keep the cylinders away from heat sources and direct sunlight.
The key to successful cleaning is not the friction force, but the correct time of aging of the chemical composition. Let the solvent do its job.
Frequently Asked Questions (FAQ)
Can I remove bitumen in the winter in the cold?
It is not recommended to use bitumen purifiers at temperatures below +5 ° C. In cold weather, the chemical reaction slows down, the product becomes less effective and may not have time to act before drying. In addition, in the cold, the lacquer becomes more fragile, and the risk of damage increases. It is better to wait for the thaw or drive the car into a warm box.
Is a bitumen cleaner dangerous for rubber mats and tires?
Short-term contact with rubber is usually not scary, but prolonged exposure can lead to drying and cracking of the rubber. If the product got on tires or mats, they should be immediately washed with plenty of water and soap. Specialized formulations labeled "Safe for plastics/rubber" are less aggressive.
How often can a bitumen cleaner be used?
Frequent use of aggressive chemicals (more often than once a month) can thin the layer of wax and polish, and in the long run – and the varnish itself. After each treatment with a bitumen cleaner, it is recommended to apply protective wax or ceramic coating to restore protection.
What to do if the cleaner hits your eyes?
Rinse your eyes immediately with plenty of clean running water for 15 minutes. If the irritation does not go away, seek medical help. Always wear safety glasses as aerosol cylinders are under pressure and can accidentally splash in an unpredictable direction.
