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 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.
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.
Rinse at high pressure in a sweeping motion
keeping the spray nozzle approximately 6
inches from the cleaning surface. For best
results, clean from top to bottom and from
left to right.
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.
Use extreme caution when cleaning decks,
siding, and other sensitive surfaces as the
pencil jet may cause damage if not used
correctly.
