CLEANING TIPS 

Deck Cleaning

(with or without detergent)
Pre-rinse deck and surrounding area with
fresh water. If using Kärcher Deck Wash,
place detergent suction tube directly into
cleaning solution and apply to surface at low
pressure. For best results, limit your work
area to smaller sections of approximately 25
square feet. Allow Kärcher Deck Wash to
remain on surface 1-3 minutes. Do not allow
detergent to dry on surface. Rinse at high
pressure in a long sweeping motion keeping
the spray nozzle approximately 3-6 inches
from the cleaning surface. Always clean
from top to bottom and from left to right.
When moving on to a new section of the
cleaning surface, be sure to overlap the pre-
vious section to eliminate stop marks and
ensure a more even cleaning result.
Caution: Do not use rotating nozzle spray
wand on wood surface as it may cause
damage.

House Siding

(with or without detergent)
Pre-rinse cleaning surface with fresh water.
If using Kärcher House Wash, place deter-
gent suction tube directly into cleaning solu-
tion and apply to surface at low pressure
(for best results, limit your work area 
to sections of approximately 6 feet and
always apply detergent from bottom to top).
Allow Kärcher House Wash to remain on
surface 1-3 minutes. Do not allow detergent
to dry on surface, if surface appears to be
drying, simply wet down surface with fresh
water. If needed, use special Wash Brush
Attachment to remove stubborn dirt. Rinse
at high pressure from top to bottom in an
even sweeping motion keeping the spray
nozzle approximately 6 inches from the
cleaning surface.
Caution: Do not use rotating nozzle spray
wand on siding as it may cause damage.

Brick and Stone

motion keeping the spray nozzle approxi-
mately 3-6 inches from the cleaning surface.

Cars, Boats & Motorcycles

tion tube directly into cleaning solution and

face. If needed, use special Wash Brush

ing the spray nozzle approximately 6-8 inch-
es from the cleaning surface (distance
