CLEANING TECHNIQUES

Pre-rinse cleaning surface with fresh water. Place de-

tergent suction tube directly into cleaning solution and

apply to surface at low pressure (for best results, limit

your work area to sections approximately 6 feet square

and always apply detergent from bottom to top). Allow

detergent 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 brush to remove stubborn dirt. Rinse at

high pressure from top to bottom in an even sweeping

motion keeping the spray nozzle approximately 1 foot

from cleaning surface. Use overlapping strokes as you

clean and rinse any surface. For best surface cleaning

action spray at a slight angle.

Recommendations:

• Before cleaning any surface, an inconspicuous

area should be cleaned to test spray pattern and

distance for maximum cleaning results.

• If painted surfaces are peeling or chipping, use

extreme caution as pressure washer may remove

the loose paint from the surface.

• Keep the spray nozzle a safe distance from the sur-

face you plan to clean. High pressure wash a small

area, then check the surface for damage. If no dam-

age is found, continue to pressure washing.

CAUTION - Never use:

• Bleach, chlorine products and other corrosive

chemicals

• Liquids containing solvents (i.e., paint thinner,

gasoline, oils)

• Tri-sodium phosphate products

• Ammonia products

• Acid-based products

These chemicals will harm the machine and will dam-

age the surface being cleaned.
