Decontamination of large equipment and vehicles
Vehicles are treated using wet chemical decontamination in a three-stage process consisting of pre-treatment, main treatment and post-treatment. During these processes, high-performance units from Kärcher treat the entire surface of the vehicle, including the underbody.
The three steps of vehicle decontamination

Pre-treatment
During pre-treatment, coarse dirt is removed from the surface of the vehicle. Cold water pressure washers are mostly used here, to gain better cleaning results and reduce the amount of water used. This removal of coarse dirt also gets rid of CBRN contaminants adhering to it. This process already considerably reduces contamination, and makes sure the surface of the vehicle is ideally prepared for the main treatment to come.

Main treatment
Decontamination agents are only applied in the main treatment phase. The suitable agent for the type of contaminant is selected and applied to the vehicle as a foam or thin film. A high-pressure pump or special application pumps are generally used for this. In some cases, thermal energy is used in addition to improve the decontamination result.

Post-treatment
During post-treatment, reaction products or particles from the main treatment process, encased by the treatment agent, are washed off the vehicle surface. Pressure washers are used for this too, to improve the cleaning result and reduce the amount of water used. In some cases, thermal energy is used additionally to improve the decontamination result.
