4. Smooth Moves
After the soap has soaked for a few minutes, you can blast away the grime to reveal the freshly cleaned siding! A white or green tip will deliver an appropriate amount of water pressure. Yellow and white tips deliver a highly concentrated and very powerful stream capable of stripping paint from the siding.
When you first start, keep the wand a couple of feet away from the siding. If you find you need more power, move very gradually closer until you are able to get a sufficient clean.
Move in even, overlapping strokes so you don't miss any spots or leave any streaks. Start from the top this time, and work your way down as you spray smoothly in a left-to-right motion.
Keep your wand angled down as much as possible to avoid getting water under the laps of the siding, otherwise the siding could buckle under pressure.
5. With Power Comes Great Responsibility
Be careful and watch where you're spraying. Don't directly spray light fixtures, windows, vents, or eaves. The high pressure of the water could cause serious damage when aimed poorly.
Likewise, be careful not to aim the pressurized water near your feet, hands, or any other person or pet. The water pressure can cause serious injury.
