effective. On vertical surfaces, apply the
detergent starting at the bottom and work your
way upward. This will prevent the detergent
from sliding down and causing streaks. High
pressure rinsing should also progress from the
bottom to top. On particularly tough stains, it
may be necessary to use a brush in
combination with detergents and high-pressure
rinsing.
OPERATION
The following cleaning procedure will help you
to organize your cleaning task and ensure that
you achieve the most beneficial results in the
shortest amount of time. Remember to use the
spraying/cleaning techniques previously listed.
1. S
URFACE PREPARATION
Before starting a pressure wash cleaning job, it
is important to prepare the surface that is to be
cleaned. This is done by cleaning the area of
furniture and making sure that all windows and
doors are closed tight. In addition, you should
make sure that all plants and trees adjacent to
the cleaning area is protected by a drop cloth.
This will ensure that your plants won’t be
sprayed by the detergents.

The next step is to spray the cleaning surface
with water to clear off any dirt or grime that
may have collected on the surface. This will
allow your detergent to attack the deep-down
dirt that has worked its way into the cleaning
surface. Before triggering the gun, adjust the
nozzle to a wide fan pattern and slowly adjust
to the desired spray pattern. This will help you
avoid applying too much concentrated spray to
the surface which could cause damage.
