6. Apply detergent from the bottom to the top of the dry
surface to be cleaned.
NOTE: Wetting the surface first is not recommended as it
dilutes the detergent and reduces its cleaning ability.
7. Allow the detergent to remain on the surface for a short
time before rinsing. Do not allow the detergent to dry on
the surface.
m
CAUTION!
Damage may occur to painted surfaces if
the detergent is allowed to dry on the surface. Wash and rinse
a small section at a time. Avoid working on hot surfaces or in
direct sunlight.

5. Select the right nozzle for the job (Fig. 21):
Fig. 21
I) The 0º intense-jet nozzle (orange) is an extremely
powerful nozzle that delivers a high-pressure, pencil-
point jet stream. It is used to cut heavy dirt deposits
in a small, concentrated area. It is ideal for dissolving
stubborn substances, like tar and grease spots on
concrete, or for removing caked mud from equipment.
Use this nozzle to clean hard-to-reach areas including
the facades of 2-story buildings or the undersides of
lawn mowers and tractors.
NOTE: Care should be used when choosing the
right nozzle to avoid permanently gouging wood or
damaging fragile surfaces.
II) Use the 15º fan-tip nozzle (yellow) for intense cleaning
jobs on hard surfaces. Applications include stripping
paint, removing oil stains, grease, heavy mildew stains,
and rust from steel. This nozzle should only be used in
areas that can withstand the high-pressure from this
nozzle.
III) Use the 25º fan-tip nozzle (green) to clean home siding,
brick patios, wood decks, driveways, or sidewalks.
When using this nozzle, test a small area first to avoid
surface damage.
