5 Fields of application and working
methods
5.1 General Effi cient high presure cleaning is achieved by following a few guide-
lines, combined with your own personal experience of specifi c
cleaning tasks. Accessories and detergents, 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 (especially by car washing).

5.2 Typical fi elds of application

Foam sprayer,
Car Combi Cleaner
1. Apply Car Combi Cleaner with the foam sprayer. Always
start from the bottom and work upwards. Let Car Combi
Cleaner act for at least 5 min.
2. Wash the car with the car nozzle, which has been optimized for
quick and gentle cleaning of enamelled surfaces (the jet is wider
and not so sharp). Start at the front of the car and work backwards to avoid water from penetrating by the door mouldings.
3. Use the brush for removal of traffi c fi lm which is not removed by the
nozzle. If the car is very dirty, apply Car Combi Clean er again.
4. Attach the undercarriage nozzle and clean undercarriage and
wheel arches.
5. Remove water from the surface of the car with the scraper
on the car brush. Make sure that all grains of sand etc. have
been removed before using the scraper. Wipe with a wash leather where the scraper cannot reach.

Be careful! The high pressure jet may damage the tyres.
Wash towards outlets or the like. On surfaces with moss or
algae you may start by applying Stone & Wood Cleaner with
the foam sprayer. Wash before the soap dries. Another
more effective and quicker method is to use the Patio
Cleaner. Thus you will also avoid splashes.
Apply Wood Cleaner and wash before the soap dries.
