5 Applications and methods
5.1 Techniques
Effi cient high pressure cleaning is achieved by following a few
guidelines, 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 Soaking
Encrusted or thick layers of dirt can be loosened or softened by a
period of soaking. An ideal method within agriculture – for example,
within pig sties. The soaking method can be achieved by use of foam
or simple alkaline detergent. Let the product lie on the dirty surfaces
for around 15 minutes before pressure washing. The result will be a
much quicker high pressure cleaning process.
Foam or detergent should be applied onto dry surfaces (not in direct
sun light) 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. 5.1.2 Detergent and Foam
5.1.3 Temperature Detergents are more effective at higher temperatures. Greases, oils
and fats can be broken down more easily at higher temperatures also.
Proteins can be cleaned at temperatures of around 60°C. Oils, traffi c
fi lm around 70°C, and grease can be cleaned at 80°C - 90° C.
5.1.4 Mechanical Effect In order to break down tough layers of dirt, additional mechanical
effect may be required. Special lances and rotary or wash brushes
offer this supplementary effect that cuts through dirt.
5.1.5 High Water Flow or
High Pressure
High pressure is not always the best solution and high pressure may
damage surfaces. The cleaning effect also depends upon water
fl ow. Pressure levels of around 100 bar may be suffi cient for vehicle
cleaning (in association with hot water). Higher fl ow levels give the
possibility to rinse and fl ush away large amounts of dirt easily.

1. Soaking – apply foam to all surfaces (bottom to top)
and wait for approx. 15 minutes.
2. Remove the dirt from surfaces with the high pressure
lance or chosen accessory. Again, clean from bottom
to top on vertical surfaces.
3. To fl ush away large quantities of dirt, change to low
pressure mode and use the higher fl ow to push away
the dirt.
4. Use recommended disinfectant products and methods
to ensure hygiene. Apply DES 3000 disinfectant once
the surfaces are perfectly clean.

Tractors
ploughs etc. Detergent injection
Powerspeed lances
Curved lances and un-
derchassis washers
Brushes 1. Apply detergent to vehicle or equipment surfaces in
order to soften up dirt and grime. Apply from bottom
to top.
2. Proceed with cleaning using the high pressure lance.
Clean again from bottom to top. Use accessories to
clean in diffi cult to reach places.
3. Clean fragile areas such as motors, rubber at lower
pressure levels to avoid damage.
