remove stubborn dirt.  Rinse at high-
pressure in a sweeping motion keep-
ing the spray nozzle approximately 
6-8 in. (15-20 cm) from the cleaning 
surface (distance should increase

keeping the spray nozzle

necessary to move the spray nozzle 
even closer to the surface for greater 
dirt cutting action.

(With or without detergent).
