During car washing, a high-pressure water
flow has a physical effect on contamination.
It is important to choose the optimal distance
between the surface of the car and the
nozzle of the spraying gun. This will help to
ensure a balance of the impact force of the
water flow. We recommend a distance of 30
cm.
The washing efficiency depends on:
- The qualities of used chemicals
- Concentrations of chemicals
- The exposure time of chemicals on
the car exterior
- Mechanical impact
- Temperature
The effectiveness of touchless car wash is
determined by the combination of the above-
listed factors. Of course, it is possible to
compensate for one of the factors with
others. For example, a lower concentration
of chemicals can be compensated by an
increase in mechanical action. But at the
same time, the increased mechanical impact
can result in scratches on the car exterior or
an increase in the concentration of shampoo
or the time of its exposure – can chemically damage the paintwork of a vehicle.
