Outdoor Cleaning with Pressure Washers

Basic Cleaning

Step 1

Always keep the nozzle in motion , spraying at a steady speed and using long, even strokes. Take multiple passes over heavily soiled areas. Take care not to dwell on one spot for too long, especially when using narrow, high-pressure spray patterns.

Step 2

Hold the spray wand so that the nozzle distributes the spray pattern across the surface evenly. Holding the nozzle at too low an angle can cause an uneven spray pattern, resulting in "zebra striping." Also, maintain a consistent distance between the nozzle and the cleaning surface to ensure consistent results and help flush dirt and debris from the area.

Step 3

Work in identifiable sections, such as the area between the expansion joints in concrete. If there is a slope, work downhill to promote drainage and help flush away dirt and debris. Wet entire surface to prevent streaking.

Step 4

When pressure washing lap siding or wood, keep the spray pattern within the width of one to two boards.

Step 5

To prevent streaks on vertical surfaces, such as fencing and house siding, always begin pressure washing or applying cleaning detergent at the bottom of the surface, then work upward.

Step 6

When rinsing vertical surfaces, start at the top and work downward. Gravity will help the clean water flush away dirt, debris, and detergent residue, in addition to preventing streaks.

Step 7

To clean out-of-reach surfaces, such as the second story of a house, use a narrow spray pattern to propel the water stream up to the surface. While enough cleaning power will remain to be effective, the spray pattern will be somewhat inconsistent and may require multiple passes. Stand behind and to the side of the spray to avoid getting wet and make sure to widen the spray pattern as you work downward.
