ANGLE TO THE CLEANING SURFACE
When spraying water against a surface,
maximum impact is generated when the water
strikes the surface “head on”. However, this
type of impact tends to cause dirt particles to
imbed in the surface, thereby preventing the
desired cleaning action.
The optimum angle for spraying water against
a cleaning surface is 45 degrees.
Spraying water against a surface at this angle
provides for the most beneficial impact force
combined with efficient removal of debris from
the surface.
DISTANCE FROM CLEANING SURFACE
Another factor that determines the impact force
of the water is the distance from the spray
nozzle to the cleaning surface. The impact
force of the water is increased as the nozzle
is moved closer to the surface.
HOW TO AVOID DAMAGING SURFACE
Damage to cleaning surfaces occurs because
the impact force of the water exceeds the
durability of the surface. The impact force can
be varied by controlling the three previously
noted items. Never use a narrow high impact
stream or a turbo/rotary nozzle on a surface
that is susceptible to damage. Avoid spraying
windows with a narrow high impact stream or
turbo nozzle as this may cause breakage. The
surest way to avoid damaging surfaces is to
follow these steps:
1.
Before triggering the gun, adjust the
nozzle to a wide fan pattern.
2. Place the nozzle approximately 4-5 feet
from and 45 degrees to the cleaning
surface, and trigger the gun.
3. Vary the fan pattern spray angle and the
distance to the cleaning surface until
optimum cleaning efficiency is achieved

DETERGENTS
The use of detergents can dramatically reduce
cleaning time and assist in the removal of
difficult stains. Some detergents have been
customized for pressure washer use on specific
cleaning tasks. These detergents are
approximately as thick as water. The use of
thicker detergents, such as dish soap, will clog
the chemical injection system and prevent the
application of the detergent.
The cleaning power of detergents comes from
applying them to a surface and giving the
chemicals time break down the dirt and grime.
The combination of chemical action and high
pressure rinsing is very 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 the top. On
particularly tough stains, it may be necessary
to use a brush in combination with detergents
and high pressure rinsing.
