Spray bottle operation- When cleaning with the pressure washer, some
cleaning tasks can be solved with water alone, but for most tasks it is
advantageous to use a detergent. A detergent ensures a quick soaking and
allows high pressure water to penetrate and remove the dirt more effectively.
The detergents must not dry on the object being sprayed with pressure
washer.
Use only detergents formulated for pressure washers. Pressure washer
detergents can be obtained at your local hardware store or automotive
store. Test detergent in an inconspicuous area before use.
How to clean surfaces and avoid damage
ANGLE TO CLEANING SURFACE
When spraying water against a surface, maximum impact is generated when the
water strikes the surface “head on”. However, this type of impact tends to cause
dirt particles to embed into the surface, thereby preventing the desired cleaning
action.
The optimum angle for spraying water against a cleaning surface is 45 degrees.
DISTANCE FROM CLEANING SURFACES
Another factor that determines the impact force of the water is the distance
between the spray nozzle and the cleaning surface. The impact force of the
water is increased as the nozzle is moved closer to the surface.
HOW TO AVOID DAMAGING SURFACES
Damaging to the cleaning surfaces occurs because the impact force of the water
exceeded the durability of the surface. Never use a narrow high impact stream
or a turbo nozzle on a surface that is susceptible to damage. Avoid spraying
windows with a narrow high impact stream or turbo nozzle as this my cause
breakage. The surest way to avoid damage to the surface are the following
steps:
1. Before triggering the gun, adjust the nozzle to a wide fan pattern.
2.
Place the nozzle approximately 4-5 feet from and 45 degrees to cleaning
surface, and trigger the gun.
3. Vary the fan pattern spray angle and the distance to the cleaning surface
until optimum cleaning efficiency is achieved without damaging the
surface
