Liqui Moly air conditioning foam cleaner: the full guide

With the onset of the hot season or, conversely, when turning on the stove in winter, many car owners face an unpleasant smell emanating from the ventilation system deflectors. This is a sure sign that the evaporator Klimaanlagen-Reiniger Bacteria and mold have settled, which actively multiply in a humid environment. Ignoring this problem not only reduces comfort in the cabin, but can also adversely affect the health of passengers, causing allergic reactions.

One of the most popular solutions in the automotive industry is air-conditioner German company Liqui Moly. This product is designed specifically for deep disinfection and cleaning of hidden cavities of the air conditioning system without the need to disassemble it. Unlike simple sprays, deodorants, foam is able to penetrate deep into hard-to-reach places, mechanically displacing dirt and destroying microorganisms.

In this article, we will analyze in detail the composition of the tool, its advantages over analogues and provide step-by-step instructions for safe use. You will learn how to properly prepare the car, what precautions to follow and how often the procedure should be carried out to maintain the perfect cleanliness of the cabin air.

Principle of operation and composition of the means

The effectiveness of any cleaning product depends on its chemical formula. foam cleaner from Liqui Moly It is based on a combination of surfactants (surfactants) and special antibacterial components. When exiting the cylinder under pressure, the gas-expeller converts the liquid into a plentiful, dense foam that increases in volume. It is this foam that provides deep penetration into the ribs of the evaporator.

The key component here is active oxygen or specific biocides that destroy the cell walls of bacteria and mold spores. The uniqueness of the Liqui Moly formula is the absence of chlorine and aggressive solvents, which makes the tool safe for aluminum parts and rubber seals of the system. After application, the foam settles, dissolves fat deposits and dust plaque, and then drains into the drainage system along with the dirt.

It is important to understand the difference between cleaning and deodorization. Ordinary fresheners simply mask the smell with fragrances, whereas air-conditioner It eliminates the very cause of the odor, the biological mass. The active substances remain on the surfaces of the evaporator, creating a temporary protective layer that prevents the rapid re-formation of bacteria colonies.

⚠️ Attention: Despite the safe composition, do not allow concentrated funds to hit the paint coating of the body or leather salon, as surfactants can leave difficult to remove spots.

The cleaning process takes place in several stages: application, waiting for a reaction and draining condensate with dirt. Liqui Moly recommends using the product at a temperature of about 20 ° C for optimal foam yield. A bottle that is too cold can produce a less efficient, watery jet that won’t penetrate deep into the system.

Benefits of using Liqui Moly aerosol

When choosing a means to service the climate system, motorists often fluctuate between different brands. Products Liqui Moly It has proven itself as a reliable solution thanks to German quality control and thoughtful packaging. The main advantage is the high penetrating ability of the foam, which fills the entire volume of the evaporator, which cannot be reached mechanically without disassembling the torpedo.

The tool does not require complex equipment or special skills. The whole procedure takes about 15-20 minutes of active time. Besides, cleaner It is compatible with all types of air conditioning systems, including modern climate control with fine filters. It does not damage the humidity and temperature sensors installed in ducts.

• 🌿 Eco-friendly: the formula contains no freon-depleting components and is safe for the environment after draining into the sewer.
• 🛡️ Anticorrosion protection: the components of the tool create a thin film on the metal that protects aluminum from oxidation.
• 💨 Smell elimination: effectively removes the smell of dampness, tobacco and mold, rather than masking them.

Another important aspect is cost-effectiveness. One 300 ml cylinder is usually enough for 2-3 complete handling of a mid-range car or for one very thorough cleaning of an SUV. This makes regular maintenance financially affordable for any car owner.

It is also worth noting the universality of application. Although the product is designed for cars, it can be used to clean air conditioners at home, if access to the evaporator allows you to enter a spray tube. However, concentration It is selected specifically for automobile volumes and air flow speeds.

Preparing the vehicle for cleaning

Before the procedure, the vehicle must be properly prepared. This will ensure maximum efficiency of work. foam-cleaner It will protect the cabin from accidental contamination. First of all, the car should be parked on a flat surface, preferably with a slight slope towards the drainage hole of the air conditioning system, if it is possible to determine visually.

The engine must be shut off and the key removed from the ignition lock. The air conditioning system must be completely turned off. Liqui Moly recommends pre-heating the cabin or, conversely, cool it to room temperature to avoid sharp changes that can affect the condensation of the foam. The optimum ambient temperature is from +10 to +25 ° C.

Be sure to remove the cabin filter. It is usually under the glove compartment or under the toad (plastic lining at the windshield). If the filter has not changed for a long time, it is better to replace it with a new one, since the washing often does not give the proper result, but only spreads dust through the system. Cleaning without changing the filter It can cause the smell to return in a couple of days.

It is important to ensure good ventilation during the procedure. Open all doors and windows. Although the composition is safe, the high concentration of solvent vapor and dislodged dirt in the air is not good for breathing. It is also worth protecting the seats and carpets with plastic film or rags in case the extension tube slips out of your hands.

Step-by-step instructions for use

The cleaning process requires care and consistency of actions. First, shake the balloon thoroughly for 5-10 seconds. This is necessary for mixing the components and the release of the displacement gas. Put a long flexible tube on the cylinder valve. The tube should be fixed tightly so that the pressure does not tear it during operation.

Turn on air recirculation in the cabin. To do this, press the button with the image of the car and the arrow inside. The fan should be turned on at maximum speed, but air conditioning (A/C button) It must remain off so that the compressor does not work. The air intake should be closed with a recirculation valve so that the foam does not go directly outdoors, but circulates through the evaporator.

Insert the end of the tube into the hole where the cabin filter was located, or direct the jet directly into the ducts if access through the filter is limited. With short presses (for 2-3 seconds), release the foam, giving it time to settle. Do not try to spew out the entire balloon in a volley - the foam should have time to dissolve the dirt. Treat the central part, left and right sides of the evaporator.
