CLEANING TIPS
Deck Cleaning
(with or without detergent)
Pre-rinse deck and surrounding area with
fresh water. If using Kärcher Deck and Patio
Cleaner, place detergent suction tube direct-
ly 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
and Patio Cleaner 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 clean-
ing result.
House Siding
(with or without detergent)
Pre-rinse cleaning surface with fresh water.
If using Kärcher House or Window and
Siding Cleaner, place detergent suction tube
directly into cleaning solution and apply to
surface at low pressure (for best results,

mately 6 feet and always apply detergent
from bottom to top). Allow Kärcher House or
Window and Siding Cleaner 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
