Understanding Pressure Washer Nozzles and Spray Angles
Pressure washer nozzles control the shape and intensity of the water spray. Choosing the correct nozzle improves cleaning performance while preventing damage to delicate surfaces.
Most pressure washers include five color-coded nozzles.
Red Nozzle (0°)
The red nozzle produces a very narrow, concentrated stream of water.
Best For
- Tough stains
- Concrete
- Metal surfaces
Avoid Using On
- Cars
- Wood
- Windows
- Vinyl siding
Use with extreme caution.
Yellow Nozzle (15°)
The yellow nozzle provides strong cleaning power with a slightly wider spray.
Best For
- Driveways
- Brick
- Concrete
- Heavy dirt
It removes stubborn grime without being as aggressive as the red nozzle.
Green Nozzle (25°)
The green nozzle is the most commonly used for household cleaning.
Best For
- Decks
- Fences
- Patios
- Outdoor furniture
It offers an excellent balance between cleaning power and surface protection.
White Nozzle (40°)
The white nozzle produces a wide, gentle spray.
Best For
- Cars
- Windows
- Painted surfaces
- Delicate cleaning
This is the safest nozzle for routine household cleaning.
Soap Nozzle (Black)
The black nozzle has low pressure and is designed to apply detergent.
Best For
- Foam cannon
- Car shampoo
- House washing
- Patio cleaning
Always rinse with a higher-pressure nozzle after applying detergent.
Which Nozzle Should You Use?
| Surface | Recommended Nozzle |
|---|---|
| Car | White (40°) |
| Patio Furniture | White (40°) |
| Fence | Green (25°) |
| Deck | Green (25°) |
| Vinyl Siding | White (40°) |
| Concrete | Yellow (15°) |
| Brick | Yellow (15°) |
| Oil Stains | Red (0°)* |
| Soap Application | Black |
Note: Use the red (0°) nozzle only on very tough stains and durable surfaces. It can easily damage paint, wood, and other delicate materials.
Nozzle Safety Tips
- Test the spray on a small area first.
- Keep the nozzle moving to avoid damaging the surface.
- Never point the spray at people or pets.
- Maintain a safe distance from the surface.
- Use the lowest pressure that effectively removes dirt.
Conclusion
Understanding pressure washer nozzles is just as important as choosing the right PSI. Each spray angle is designed for a specific cleaning task, and selecting the correct nozzle helps you achieve better results while protecting your surfaces. For most household jobs, the green (25°) and white (40°) nozzles are the safest and most versatile choices.
