5  Applications and methods

Efficient high pressure cleaning is achieved by following a few 
guidelines, combined with your own personal experience of specific 
cleaning tasks. Accessories and detergents, when correctly chosen, 
can increase the efficiency 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 up by 
a period of soaking. This is for example an ideal method within agri-
culture – for example, within pig sties. The ideal soaking method can 
be achieved via use of foam or simple alkaline detergent. Let the 
product lie on the dirty surfaces for around 10 - 30 minutes before 
pressure washing. The result will be a much quicker high pressure 
cleaning process.

5.1 Techniques

5.1.2  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.

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, 
traffic film 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 
flow. Pressure levels of around 100 bar may be sufficient for vehicle 
cleaning (in association with hot water). Higher flow levels give the 
possibility to rinse and flush away large amounts of dirt easily.
