CLEANING TIPS 

8

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 approxi-
mately 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
previous 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
solution and apply to surface at low pres-
sure (for best results, limit your work area 
to sections of approximately 6 feet and
always apply detergent from bottom to top).
Allow Karcher 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.

Cement Patios, 
Brick and Stone 

(with or without detergent)

Pre-rinse cleaning surface with fresh water.
If using Karcher All Purpose Cleaner, place
detergent suction tube directly into cleaning
solution and apply to surface at low pres-
sure. For best results, limit your work area
to smaller sections of approximately 25
square feet. Allow Kärcher All Purpose
Cleaner to remain on surface 1-3 minutes.
Do not allow detergent to dry on surface.
Rinse at high pressure in a sweeping
motion keeping the spray nozzle approxi-
mately 3-6 inches from the cleaning sur-
face. Always clean from top to bottom and
from left to right. For removing extremely
stubborn stains, use Kärcher Rotating
Nozzle Spray Wand.

Cars, Boats & Motorcycles

(with or without detergent)

Pre-rinse vehicle with fresh water. If using
Karcher Vehicle Wash, place detergent suc-
tion tube directly into cleaning solution and
apply to surface at low pressure. For best
results, clean one side of vehicle at a time
and always apply detergent from bottom to
top, do not allow detergent to dry on sur-
face. If needed, use special Wash Brush
Attachment to remove stubborn dirt. Rinse
at high pressure in a sweeping motion
keeping the spray nozzle approximately 6-8
inches from the cleaning surface (distance
should increase when rinsing pin-striping 
or other sensitive surfaces). Always clean
from top to bottom and from left to right.
For best results, wipe surface dry with a
chamois or soft dry cloth. 

Caution: Do not use rotating nozzle
spray wand on vehicles as it may
