clean and rinse any sur face. For best surface clean ing
action spray at a slight an gle.

• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
dis tance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use
ex treme caution as pressure washer may re-
move the loose paint from the surface.
