SURFACE PREPARATION
Before cleaning with a pressure washer, it is important to prepare the surface to be
cleaned. This is done by removing unnecessary objects and making sure that all
windows and doors are tightly closed. In addition, make sure that all plants and trees
adjacent to the area to be cleaned are properly sheltered. The plants will not be sprayed
with detergents as a result.
PRE-RINSING UNDER HIGH PRESSURE
The next step is to spray the surface with water to remove any dirt that may have
accumulated there. This will allow the detergent to attack deeply embedded dirt that
has adhered to the surface. Before squeezing the gun trigger, set the nozzle to a wide
spray pattern and slowly adjust it to the desired spray pattern. This will help to avoid
spraying the surface with too much concentrated spray, which could cause damage.
DETERGENT APPLICATION
NOTE: Use only detergents designed for pressure washers.
NOTE: Before use, test the detergent on a hidden area.
