CLEANING TIPS
– continued
Barbeque 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, wheelbarrows or other
non-sensitive metal surfaces, you may
want to use the Kärcher Dirtblaster
®
Nozzle.
Caution: Do not use Dirtblaster
®
spray
nozzle on cloth, plastic or other sensitive
surfaces as it may cause damage.

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

Do not allow detergent to dry on surface.
Rinse at high pressure 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 Dirtblaster
®
nozzle on
patio or lawn furniture as it may cause
damage.
Recommendations
