The oil pallet is the bottom of the engine lubrication system, which is constantly exposed to aggressive environmental influences, and the dirt, reagents, water and, of course, oil dripping from the gaskets or the oil glands, creates a dense layer of lobe, which not only spoils the appearance of the car, but also degrades the heat sink, which is critical for the life of the engine.
Many car owners are asking themselves, squirtThere are many ways, from aggressive chemistry to proven folk methods, and it is important to understand that the choice of product depends on the degree of contamination and the material of the pallet itself (aluminum or steel).
In this article, we will discuss professional solvents, household cleaners and mechanical methods of removing dirt, you will learn how to safely perform the procedure without removing the part from the car, and what precautions should be taken when working with caustic compounds.
Types of pollution and choice of cleaning product
Before cleaning, you need to assess the nature of the contamination. Common dust is washed away by water, but oil film mixed with bitumen and road dust requires a more serious approach. Oily scoop It has the property of polymerizing under the influence of high temperatures, turning into a solid crust.
For fresh oil stains, conventional degreasers or white spirits are great. flush out And the multi-year tar layers, they require specialized tools, which contain active components that break down complex hydrocarbons.
When choosing chemistry, consider the composition. Acid cleaners can damage aluminum alloys by causing corrosion; alkaline products are safer for metal but require careful flushing; for plastic suspension elements located nearby, aggressive chemistry can also be dangerous.
Important: Some formulations can damage the paint on the pallet itself or adjacent body elements. Always check the reaction of the product on an inconspicuous area.
Before applying any chemical, warm the engine to operating temperature, but not to a hot state. Warm metal responds better to cleaners, and the process goes faster.
Professional Autochemistry for Engine Cleaning
The modern market offers a wide range of specialized cleaners, divided into aerosol cylinders and concentrates for dilution with water or solvent, and aerosols are convenient for point treatment of hard-to-reach places where the brush will not crawl.
Concentrates, such as Liqui Moly, Hi-Gear or FelixThey are often used in professional washers, they have high penetrating power and effectively emulsify oil, and often they don't require even mechanical friction, so you just rinse the foam with water under pressure.
- 🧪 Bitumen stain cleaners They do well with road tar, but can be aggressive to rubber.
- 🚿 Engine foam cleaners - are applied to a cold or warm engine, foam and wash out dirt.
- 🛢️ Universal degreasing agents - suitable for regular care, but old garment may not cope.
When working with professional chemistry, be sure to use personal protective equipment. solvent vapors are toxic, and getting concentrate on the skin causes burns. Ventilation Work or work in the open air is mandatory.
Folk methods and available solvents
You don't always have the ability or the desire to buy expensive auto chemicals, and experienced drivers have been using affordable products for decades, often as good as branded ones. diesel or kerosene.
Diesel dissolves oil very well and doesn't evaporate as quickly as gasoline, allowing it to penetrate deep layers of dirt, but it leaves a greasy film that you still have to wash off, it's more aggressive, it's better at defatting, but it's fire-prone and it's bad for rubber hoses.
Another effective method is the use of soda-calcifiedSoda solution in hot water (porridge) is applied to contaminated areas and left for a while. The alkaline reaction breaks down the fatty deposits. After that, the dirt is easily washed away with water.
⚠️ Warning: Never use pure gasoline to wash the engine in a hot car or in an enclosed space. Gasoline vapors are heavier than air and can flare up from the spark of a starter or generator.
It's also popular. WD-40 Although it was originally designed as a water repellent, it is a great way to deal with rust and light oil pollution.
Mechanical cleaning: tools and technologies
Chemistry works wonders, but without mechanical action, it's hard to deal with old-fashioned soda. You'll need brushes with different stiffnesses to work with. Plastic brushes are safe for aluminum, metal brushes can leave scratches that become centers of corrosion.
To remove a thick layer of "plasticine" dirt is convenient to use scraper It's a soft metal, or even a wooden spatula, and the key is not to damage the integrity of the pallet, or to break the drain plug thread, and after the chemical has been softened, the dirt is cleared with light movements.
If the pallet has a complex embossed surface (ribs), use brushes for hard-to-reach areas. Ideally, after chemical treatment and mechanical cleaning, you need to wash the residues with water under pressure (Kercher).
- 🖌️ Painting brushes - to apply chemistry to narrow slits.
- 🪥 Toothbrushes - Perfect for cleaning threads and small parts.
- 🧽 Abrasive sponges - for the final polishing of the surface after removal of the main coar.
Remember, mechanical action can damage the oil or temperature sensors if they're protruding into the pallet.
Can I wash the engine with a kerkercher?
You can, but with caution. Don't direct a high-pressure jet of water directly to the electrical connectors, generators and air intakes. You'd better use foam mode or low pressure to flush the chemistry.
Comparison of cleaning methods: efficiency table
To make it easier for you to choose, pan-wash In your case, we've put together a comparative chart that will help you estimate the amount of time, money and effort that you're spending.
| Method | Efficiency | Safety for metal | Cost |
|---|---|---|---|
| Special. Aerosols. | High. | High. | Medium |
| Diesel fuel | Medium | High. | Low. |
| Soda ash | High. | Medium (oxidation risk) | Low. |
| petrol | High. | High. | Low. |
As you can see from the table, specialized tools benefit from a combination of safety and convenience factors, but when budgets are tight, traditional methods also have the right to live in safety.
When choosing a method, consider the material of the pallet. Aluminum is softer and more chemically active than steel. Steel pallets are often covered with enamel, which is easily damaged by abrasives or strong acids.
The safest and most effective method is combined: applying a professional foam cleaner, exposure of 5-10 minutes and flushing with low pressure water.
Safety and vehicle preparation
The process of washing the engine and pallet requires strict compliance with safety rules, especially with regard to the protection of electrical equipment, water and chemistry should not get to the generator, starter, fuse block and candle wells.
Before the start of work, it is recommended to close sensitive nodes with polyethylene or special caps. Battery It is better to remove or carefully isolate the terminals, since the electrolyte hit (if it leaks) or the closure of the water can disable the electronics.
Work with chemical-resistant gloves and safety glasses. Cleanser sprays that get into your eyes can cause serious damage to your cornea. If that happens, wash your eyes immediately with plenty of water.
⚠️ Warning: Do not wash the engine if it is hot. Dramatic cooling can cause the cylinder head to deform or crack in the exhaust manifold.
It is also important to ensure good ventilation if you wash your car in the garage, and solvent vapors build up below, near the floor, and can cause choking or poisoning.
☑️ Preparation for pallet washing
Final treatment and protection of cleaned surface
After you've succeeded. rinseThe metal is prone to oxidation, and moisture residue can start the corrosion process, so it's important to finish the procedure correctly.
It's recommended that you blow out hard-to-reach areas with compressed air to get the water out of the joints and mounts. Then let the engine dry completely. To speed up the process, you can start the motor for 5-10 minutes, the heat will dry out the moisture.
It can be used to protect against future pollution. heat-resistant They create a film that gets less dirt stuck to it, and the next time you wash it, it gets washed away much more easily, and it also gives the engine a neat, store-like look.
Regular, at least superficial washing of the hood space (once every six months) will prevent the formation of thick layers of sodium, which then have to be cleaned with the risk of damaging parts.
Why blacken the pallet after washing?
Heat-resistant paint or ink not only improves the appearance, but also creates a barrier layer. To a smooth painted surface, oil dust sticks less than to rough oxidized aluminum.
Can I wash the engine pan with gasoline?
Technically, gasoline is a great solvent, but it's dangerous because of the high flammability of vapors and aggressive to rubber pipes and plastic cells, and it's better to use less aggressive solvents.
How often should the engine and pan be washed?
It is recommended to carry out a thorough wash once a year or when selling a car. Surface removal of dust and dirt can be done more often, for example, at every second wash of the body, if gentle chemistry is used.
Is the kerkerker dangerous to the engine?
Yes, if you use a narrow jet nozzle with high pressure (turbo nozzle), it can penetrate the hood insulation, damage the cells of the radiator or drive water into electric connectors. Use a wide fan stream.
How to wash oil from an aluminum pallet without chemistry?
Without specialized chemistry, it's hard. You can try hot soap solution and hard brush, but the efficiency is low. You'd better buy an inexpensive universal cleaner from a car store.
