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 experi-
ence of specifi c cleaning tasks. Accessories and deter-
gents, when correctly 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 bodywork, in order to avoid "super clean" areas,
where the detergent collects in higher concentration 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 surfac 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. Special wash brushes
offer this supplementary effect that cuts through dirt (es-
pecially by car washing).
