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 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
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 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 House or Window and Siding
Cleaner, 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 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 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 rotary spray wand on
siding as it may cause damage.

(with or without detergent)
Pre-rinse cleaning surface with fresh water. If
