We had some fun making this video to demo the potential power of each nozzle. We only demo the 25, 15, 0, and Rotary, but it should give you a pretty good visual of what each nozzle can do. Note that the machine used in this video is a 3-gallon per-minute, 3,000 PSI machine for industrial use. Homeowner-grade equipment results will vary. But the same principles apply when it comes to nozzle cleaning power.

Pressure washer nozzle colors are the quickest way to identify what degree a nozzle is. 

So what degree nozzle is best for the job I have? In other words, what do the different colored nozzles do? We’ll start with the least destructive and work our way up.

What pressure washer nozzle color to use?

Black or Brass Soap Pressure Washer Nozzles


Pressure washer soap nozzles are typically low-pressure and used for applying detergents to whatever you are cleaning. Typically these nozzles are 500psi with a 65° spray pattern. These nozzles can also be used for rinsing or light cleaning applications.

  • Applying detergents, such as soap or chemicals
  • Light rinsing
  • Light Cleaning Applications

White Pressure Washer Nozzles


The white nozzles produce a 40-degree spray pattern. This wide pattern gives you higher pressure but a wide spread of water.

  • Great for sweeping or clearing larger areas
  • Cleaning up leaves or grass from sidewalks or patios
  • House siding
  • Windows or glass surfaces
  • Also great for rinsing soap or chemicals

Green Pressure Washer Nozzles


Green nozzles produce a 25-degree spray of water and concentrate your cleaning power. The green nozzle is excellent for cleaning houses, cars, boats, RVs, and wood surfaces like decks. It is also a perfect choice for prepping surfaces for painting.

  • House cleaning
  • Decks and fences
  • vehicles, cars, trucks, boats, RVs

Yellow Pressure Washer Nozzles


Yellow pressure washer nozzles are the go-to nozzle for most users. Yellow nozzles provide a 15-degree spray pattern. They offer excellent cleaning power and precision. A 15-degree nozzle is the way to go when the mess gets more stubborn.

  • stripping painted surfaces
  • Grease, oil, and petroleum messes.
  • Sticky adhesives
  • Removing gum
  • Anything the green nozzle didn’t tackle
  • Industrial and Construction Equipment

Red Pressure Washer Nozzles


Red nozzles produce a 0-degree spray pattern. These nozzles are typically for cutting or dislodging large debris chunks (caked mud or grease). The 0-degree is highly aggressive and should be used with the utmost caution. Damage to surfaces can happen quickly and easily. 

  • Dislodging large chunks of debris
  • Removing grout
  • Cleaning expansion joints
  • Slicing watermelons
  • Boring or drilling in soil

Rotary Nozzles for Pressure Washers


Rotary nozzles, sometimes known as turbo nozzles, are arguably the most fun to use. Combining the power of a 0-degree nozzle pattern with quick spinning rotation allows for powerful cleaning with a wide coverage area. These nozzles are brass on stainless steel with a ceramic nozzle and seat. To prevent nozzle damage, always start these nozzles facing the ground. Just like the 0-degree nozzle, caution is recommended when using this nozzle. Damage to surfaces can happen quickly.

  • Cleaning large, highly stained hard surfaces, such as concrete
  • Removing graffiti
  • Removing gum
  • Cleaning stone or retaining walls
  • Large grease or mud build-up
  • Digging or trenching in soil
  • Farm use in confinements
