5 Fields of application and working methods
5.1 General
Effi cient high presure cleaning is achieved by following a few guidelines, combined with your
own personal experience of specifi c cleaning tasks. Accessories and detergents, when correct-
ly chosen, can increase the effi ciency of your pressure washer. Here is some basic information
about cleaning.
5.1.1 Detergent and foam
Foam or detergent should be applied onto dry surfaces so that the chemical product is in direct
contact with the dirt. Detergents are applied from bottom to top, for example on a car body-
work, in order to avoid "super clean" areas, where the detergent collects in higher concentrati-
on and streams downwards. Let the detergent work for several minutes before rinsing but never
let it dry on the surface being cleaned. Note: It is important that the detergents do not dry up.
Otherwise the surface that has to be cleaned can be da maged.
5.1.2 Mechanical effect
In order to break down tough layers of dirt, additional mechanical effect may be required. Spe-
cial wash brushes offer this supplementary effect that cuts through dirt (especially by car wash-
ing).
