How to Choose or Use the Best Pressure Washer for a Deck
Choosing the best pressure washer for your deck requires more than just picking a powerful model. You’ll need to consider wood type, nozzle angle, and safety practices.
Match PSI to Your Deck Material
- Softwood (Cedar, Pine): 1,200–1,500 PSI
- Hardwood (Mahogany, Ipe): 2,000–2,500 PSI
- Composite Decks: 1,000–1,200 PSI to avoid damage
Avoid going above 3,000 PSI, as this can strip away protective layers or fibers.
Choose the Right Nozzle
- 40° (White): Best for delicate woods and general cleaning.
- 25° (Green): Ideal for deep dirt and mildew removal.
- 15° (Yellow): Use only on tough stains and with caution.
Always start with the widest angle and test on a small area first.
Proper Technique Matters
- Keep the nozzle 12–18 inches away from the surface.
- Move consistently with the grain of the wood.
- Avoid lingering in one spot to prevent gouging.
- Allow your deck to dry for 24-48 hours before sealing or staining.
For professional-level results, companies like CR Maids use specialized surface cleaners that ensure even water distribution.
