#1 Using the incorrect nozzle:
The shape and intensity of the spray pattern are determined by the nozzles attached to the end of the power washer spray wand. There are three primary types of nozzles: fan, flat, and needlepoint. Fan nozzles have the most extensive spray pattern, flat nozzles have a more concentrated spray pattern, and needlepoint nozzles have the most focused spray pattern of all. The fan nozzle has the biggest opening and is best for covering large areas quickly or spraying liquid soap if your pressure washer has an onboard reservoir. You can also use the fan nozzle on siding, decks, and driveways. When it comes to brickwork, a flat nozzle is an ideal option. It has an intense cleaning action, but it isn't so strong that it damages the brick. The closest angle nozzle is appropriate for surfaces resistant to harm and needs vigorous cleaning. Always test any surface carefully with the spray nozzle a few feet away at first.
#2 Failure to occasionally inspect and clean the inlet filter:
Most Pressure Washers contain a little screen filter in the fitting where the garden hose connects. This filter protects the pump from debris, but it must also be kept clean for water to flow correctly into the power washer. It only takes a few seconds to inspect the screen before connecting the garden hose and, if necessary, cleaning it.
#3 Not using enough water when power washing wood surfaces:
Power washers knock the dirt off surfaces, but it will remain after the surface dries unless the land is cleaned away by water. It is particularly problematic on horizontal surfaces such as decks. Always power washes for a long enough time and enough water to remove all dirt from the surface. Without sufficient water flow over the surface and onto the ground, Insufficient water flow over the surface and onto the floor will not completely clear dirt, mold, and mildew.
#4 Cleaning with insufficient soap or detergent:
If your pressure washer has a soap reservoir, use it liberally when applying any form of cleaning chemical to surfaces, and let it stay for a few minutes before rinsing off for the best impact. It will help dislodge mold and filth, making following power washing passes more effective.
#5 Relying just on pressure cleaning:
There are occasions when pressure washing alone is insufficient to clean surfaces. Scrubbing with a soft brush as part of the power washing process, as strange as it may sound, is often required for the cleanest results. For this, use a long-handled brush with a hose hookup. It works effectively after an initial power wash and before a final power-washing rinse.
Pressure washing is a popular home maintenance activity because it extensively cleans bricks, siding, decks, and machinery in a short amount of time. Please visit us to learn more about pressure washer tips and tricks.
