CLEANING TIPS
Deck Cleaning
(with or without detergent)
Pre-rinse deck and surrounding area with
fresh water. If using Kärcher Deck + Fence
Wash, 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.
Caution: Do not use rotary spray wand on
wood surfaces as it may cause damage.
House Siding
(with or without detergent)
Pre-rinse cleaning surface with fresh water. If
using Kärcher Pressure Wash, 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.
Caution: Do not use rotary spray wand on
siding as it may cause damage.
Cement Patios, Brick and
Stone

high pressure in a sweeping motion keeping

sensitive surfaces). Always clean from top to
