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
3.Vary the fan pattern spray angle and the distance to the cleaning surface until optimum cleaning efficiency is achieved without damaging the surface
