CLEANING TIPS
(with or without detergent).
Pre-rinse furniture
and surrounding area with fresh water. If using
Pressure Wash, apply to surface at low pressure.
Allow Pressure Wash to remain on surface 1-3
minutes. Do not allow detergent to dry on surface.
If needed use special Wash Brush Attachment (not
included) 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.
