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 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.
House Siding
(with or without detergent)
Pre-rinse cleaning surface with fresh water.
If using Kärcher Pressure Wash, place
detergent suction tube directly into cleaning
solution 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 Pressure 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 (not included) 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.
