The short answer
Red is 0°, yellow 15°, green 25°, white 40° and black is the low-pressure soap tip. For nearly every homeowner job use green (25°) or white (40°). Yellow is for stubborn concrete, and red should stay in the box — it cuts wood, paint and skin.

The color code is a universal standard across brands, which means a nozzle set from one manufacturer works on another machine with the same quick-connect. Getting the color right is the single biggest factor in not damaging what you're cleaning.
| Color | Angle | Use on | Never use on |
|---|---|---|---|
| Red | 0° | Rust spots, tar, spot removal at distance | Wood, paint, siding, anything soft |
| Yellow | 15° | Stubborn concrete, stripping paint | Wood decks, vinyl siding, cars |
| Green | 25° | Decks, siding, pavers, general cleaning | Delicate window seals |
| White | 40° | Cars, windows, painted surfaces, soft wood | Nothing — safest tip |
| Black | Soap (low pressure) | Applying detergent | Rinsing — it has no pressure |
Why the Black Tip Matters
Most washers only pull detergent through the black low-pressure tip. If your soap isn't coming out, the wrong nozzle is the usual reason — the high-pressure tips create too much restriction for the siphon to work.
What Distance Does
Spray angle and distance work together. A 25° tip held 4 inches from wood does more damage than a 15° tip held 18 inches away. When in doubt, widen the angle and back up; both lower the force on the surface.
Frequently Asked Questions
- What nozzle should I use on vinyl siding?
- Green (25°) for general cleaning, white (40°) near windows and trim. Spray downward at a slight angle so water doesn't get driven behind the siding.
- What nozzle is best for a wood deck?
- Green (25°) held 10–12 inches away, or white (40°) on older soft boards. Never use yellow or red on wood.
- Are pressure washer nozzles universal?
- The 1/4-inch quick-connect size is standard on most homeowner machines, so color-coded sets interchange. Check your machine's GPM rating matches the nozzle set's orifice size.
