CAUTION:
Since a turbo nozzle uses a
narrow high impact stream, only use it in
applications where the cleaning surface
cannot be damaged by narrow high impact
spray. Additionally, the turbo nozzle is NOT
adjustable and cannot be used to apply
detergent.
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 to break down the dirt
and grime. Detergents work best when
applied at low pressure.
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 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. Surface 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 are protected by a drop cloth. This will
ensure that your plants won't be sprayed by
the detergents.
