4. Smooth Moves
Now you're ready to blast the soap and grime away and reveal that beautiful cedar. Use a white or green tip to deliver a moderate amount of water pressure. Yellow and white tips are much stronger and more concentrated, and will strip paint or sealant off of the wood.
When you're ready to begin, keep the wand two feet away from the siding. Then move gradually closer should you need more power.
Once again, move your wand in even, overlapping strokes to avoid missing spots or leaving streaks. Start from the top this time, and work your way down as you spray smoothly in a side to side 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
Keep your eyes open 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.
