Original instructions
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 agricul-
ture – 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 30 minutes before pressure wash-
ing. The result will be a much quicker high pressure cleaning process.
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 before rinsing but never let it dry on
the surface being cleaned.
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.
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.
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.
Method
1. Soaking – apply foam to all surfaces (bottom to top)
and wait for approx. 30 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 flush away large quantities of dirt, change to low
pressure mode and use the higher flow 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.
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 difficult to reach places.
3. Clean fragile areas such as motors, rubber at lower
pressure levels to avoid damage.
