Standard Pressure Washer Nozzle Color Guide
Match your nozzle angle to the surface before pulling the trigger to prevent gouging, etching, or motor burnout.
| Color / Angle | Spray Pattern | Best Used For | Caution & Limits |
|---|---|---|---|
| Red (0°) | High-pressure pinpoint pencil jet | Stubborn concrete stains, baked-on mud clods, high-reach exterior spots | Will gouge wood, strip paint, and cut skin. Never use on vehicles or siding. |
| Yellow (15°) | Narrow chisel spray fan | Heavy stripping, rust removal, surface paint prep, oil grime on driveways | Keep back 12+ inches on masonry. High risk of cutting into soft wood or composite decks. |
| Green (25°) | General flushing medium fan | Driveways, brick walkways, patios, sidewalks, sweeping loose debris | Standard all-around cleaning tip. Keep a steady sweep distance to avoid visible stripe marks. |
| White (40°) | Wide gentle fan | Vinyl siding, stucco, windows, cars, outdoor furniture, painted wood | Safe for fragile surfaces. Lower impact pressure; ideal for washing down detergents. |
| Black (65°) | Low-pressure wide brass tip | Applying soap, detergents, and chemical soft-wash solutions | Cannot strip dirt; soap injector only. Low PSI drop triggers chemical siphoning. |
