Cleaning tips to protect against viruses, bacteria & germs

Learn everything you need to know now about cleaning.

Washing our hands protects us from viruses and bacteria

Washing our hands protects us from viruses and bacteria. Cleaning the air conditioning is just as important for our health.

Hand washing shows why the regular cleaning of car air conditioning systems plays such a major role in our good health. Regular hand washing with soap is not just a key part of life during pandemics and the annual flu season. We also have to do it during our “normal” everyday lives to protect us from bacteria, viruses, germs and fungi.

Micro-organisms can enter our bodies not only through the objects we touch, but also through the air we breathe: outdoors in nature, in buildings and even in cars – as a result of dirty air conditioning systems.

This is exactly why regular hygienic cleaning of air conditioning systems is just as important for our good health as daily hand washing is.


Sinner’s Circle

The four factors behind every effective cleaning job

How is efficient cleaning defined, and which factors play a role in it? An effect mechanism that is critically important to all cleaning processes is the Sinner’s Circle.

According to this principle, the effectiveness of cleaning is based on four factors: the cleaning agent, the mechanics, the time and the temperature.

  • The cleaning agent triggers the cleaning process, loosens foreign matter and holds it in suspense until it is transported away.
  • The mechanics can be performed by brushes, sponges, hydraulic pressure (in the case of airco well®) or gas pressure. The mechanic force shortens the application time of the cleaning agent and accelerates the cleaning process.
  • Another factor is the application time of the cleaning agent, that is the time between the cleaning agent is applied and the foreign matter is absorbed.
  • Finally, the cleaning process can be accelerated further by increasing the temperature of the cleaning agent in use.

All four parameters interact with one another and can be used to different degrees. If the role of one factor is expanded, then the total effect of the remaining three factors decreases.

If two or more parameters are changed, the interplay of the factors must be carefully coordinated in the end to achieve the same cleaning result.

Let’s now take the example of hand washing one step further: If you reduce the water temperature, you will have to wash your hands longer (time), rub them more intensely (mechanics) or use more soap (cleaning agent) to achieve the same cleaning result.

The effect mechanism can be applied to the cleaning of a car air conditioning in the very same way: The key factors:

  • the airco well® cleaning solutions 996 and 994,
  • the special high-pressure rinsing produced by the pressure cup gun,
  • the length of the cleaning process and


The VDI (Association of German Engineers) recommends: cleaning with airco well®

The VDI guideline 6032 recommends regular cleaning

As an important guideline provider, the Association of German Engineers (VDI) has also taken up the need for car air conditioning systems to be cleaned regularly. VDI Guideline 6032 recommends a procedure for this which describes the current state of the art. The method used by TUNAP consisting of cleaning the pollen filter environment, changing the pollen filter and cleaning the air conditioning system evaporator corresponds to this procedure.

This means that airco well® has been proven to be the best solution for healthy breathing air in the car, as shown by comprehensive internal and independent external tests.

For example, the ECARF Institute (European Center for Allergy Research Foundation) has awarded the airco well® process the title of allergy-friendly.
