Why Your Car's Air Conditioner Smells

Your car's air conditioning system provides heat relief in the summer and clears up foggy windows on cold or rainy days. The ability to pull moisture from the air is also directly related to an unpleasant odor that can develop when running the air conditioner. The core of the air conditioning system, which draws moisture from the air in order to cool it and reduce humidity, is a haven for pollen, dust, and odor causing pollutants due to constant moisture exposure. 

Klima Cleaner Pro is a highly effective, water-based cleaner for the air conditioning system. It removes pollen and dust while eliminating sources of odor by flushing the evaporator core. With one treatment, you'll achieve cleaner and fresher smelling air and possibly improve the cooling efficiency of the evaporator. Plus, the results are long-lasting and Klima Cleaner doesn't contain harsh or aggressive chemicals. 

Caution: This application method will require you to disassemble interior trim and is recommended for advanced users only. Nextzett USA is not liable for any damage that may occur if the procedure is done incorrectly.

 

Directions

Step 1evaporator-diagram.jpg

Read directions completely before application. Please do this so you have an idea of what to expect.

Step 2

Turn off vehicle power.

Step 3

Once glove box is removed, remove blower fan to have open access to ducting that leads directly to evaporator (you will need to refer to instructions for removing the blower fan from your car's vehicle manual, forum boards, etc). A video at the end of this tutorial shows Klima Cleaner applied to a vehicle in which the the blower fan was removed.

Step 4 

Shake Klima Cleaner Pro can well prior to application. For cleaning the automotive evaporator, remove the included red direct application sprayer from the top of the can and attach the supplied application tube to the can.

FYI, the red direct sprayer is for use if you plan on cleaning a non-automotive AC unit such as your house AC's condenser or a window unit.

Step 5 

Insert tube as far into ducting and dispense entire contents of can - about 1-2 minutes. While dispensing, hold can as upright as possible. DO NOT invert can. As you spray, the solution will foam on to the evaporator and surrounding evaporator housing.

Step 6 

After dispensing product, wait 20 minutes for product to clean the system. During this time this would be a good time to replace the cabin air filter. 

The filter was replaced on this vehicle and you can see how dirty it is. By replacing it with a clean one, you will remove any possible remaining odor causing contaminants, improve air flow, and allow the air conditioner to run more efficiently.

Step 7

Re-install all components such as the blower, cabin air filter (if removed) and glove box. You'll also notice at this time that the product will be draining from underneath the car.

Cleaning solution will drain through the drain tube of the evaporator housing.    

Step 8 

After the 20 minutes are complete, open windows to allow fresh air to enter vehicle. Turn on fan to maximum setting with A/C setting in ON position for approximately 1 minute to dry system.

Procedure is now complete!

 

Follow-up

Treat your system once a year or as necessary to clean the air conditioning system and keep your cabin air clean, healthy and smelling fresh!

einszett Comes to North America

In 2000, einszett entered the North American market for the first time, beginning with a small number of specialty dealers who recognized the quality and potential of the brand.

Among the earliest was Newport Beach Porsche, which became einszett’s first dealer in 2001. From those first placements, English-language product labels, catalogs, and marketing materials helped introduce einszett to a new audience of enthusiasts and professionals in the United States and beyond.

The Products That Defined an Era

From groundbreaking formulations to iconic packaging, these products shaped the automotive detailing industry and set new standards for excellence.

Gummi Pflege Stift

One of einszett’s most recognizable products in North America. Gummi Pflege became a favorite for conditioning rubber weather seals, helping reduce sticking, squeaks, and freezing in cold weather.

Cockpit Premium

One of the products that changed expectations for interior care. Cockpit Premium was among the first interior detail sprays to leave a factory-matte finish instead of the glossy look common at the time, setting a standard that many later products would follow.

Glanz Wax

At a time when carnauba waxes dominated the market and synthetic protection was still relatively uncommon, Glanz Wax offered a pure synthetic polymer alternative. It stood alongside early enthusiast favorites such as Klasse and Zaino as part of the shift toward longer-lasting synthetic paint protection.

Kristall Klar helped lead the move toward highly concentrated windshield washer additives long before concentrated tablets and similar formats became common. A small bottle treated a large volume of washer fluid while delivering strong cleaning and low-streak performance.

Part of the Enthusiast Community

From Porsche events and club gatherings to dealer shows and trackside sponsorships, einszett became part of the enthusiast community it served.
