CLEANING TIPS
- continued
Barbecue Grills, Outdoor
Power Equipment &
Gardening Tools
(with or without detergent)
Pre-rinse cleaning surface with fresh water.
If using Kärcher All Purpose Cleaner or
Degreaser, place detergent suction tube
directly into cleaning solution and apply
detergent at low pressure. Allow Kärcher
detergent to remain on surface 1-3 minutes.
Do not allow detergent to dry on surface.
Rinse at high pressure keeping the spray
nozzle approximately 3-6 inches from the
cleaning surface. For removing extremely
stubborn dirt, it may be necessary to move
the spray nozzle even closer to the surface
for greater dirt cutting action. To remove
caked on mud from garbage cans, lawn
mower blades, wheel barrels or other
non-sensitive metal surfaces, you may
want to use the Karcher Rotating Nozzle
Spray Wand.
Caution: Do not use rotating nozzle spray
wand on cloth, plastic or other sensitive
surfaces as it may cause damage.
Patio & Lawn Furniture
(with or without detergent)
Pre-rinse furniture and surrounding area with
fresh water. If using Kärcher All Purpose
Cleaner, place detergent suction tube direct-
ly into cleaning solution and apply to surface
at low pressure. Allow Kärcher All Purpose
Cleaner to remain on surface 1-3 minutes.
Do not allow detergent to dry on surface. If
needed use special Wash Brush Attachment
to remove stubborn dirt. Rinse at high pres-
sure in a sweeping motion keeping the
spray nozzle approximately 3-6 inches from
the cleaning surface. For best results, clean
from top to bottom and from left to right.
Caution: Do not use rotating nozzle spray
wand on patio or lawn furniture as it may
cause damage.
Recommendations
• Before cleaning any surface an inconspic-
uous area should be cleaned to test spray
pattern and distance for maximum clean-
ing results.
• If painted surfaces are pealing or chipping,
use extreme caution as pressure washer
may remove the loose paint from the
surface.
