CLEANING TIPS  – 

continued

Barbecue Grills, Outdoor
Power Equipment & 
Gardening Tools 

(with or without detergent)
Pre-rinse cleaning surface with fresh water. If
using Kärcher Pressure Wash 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 deter-
gent to dry on surface. Rinse at high pres-
sure 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 sur-
faces as it may cause damage.

Patio & Lawn Furniture

(with or without detergent)
Pre-rinse furniture and surrounding area with
fresh water. If using Kärcher Pressure Wash
place detergent suction tube directly into
cleaning solution and apply to surface at low
pressure. Allow Kärcher Pressure Wash 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 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 rotating nozzle spray wand on patio or
lawn furniture as it may cause damage.

Recommendations

• Before cleaning any surface an inconspicu-

ous area should be cleaned to test spray
pattern and distance for maximum cleaning
results.

• If painted surfaces are pealing or chipping,

use extreme caution as pressure washer
may remove the loose paint from the 
surface.
