Beginner’s Guide to Pressure Washer Nozzles and What They Do 

Choosing the right pressure washer nozzle is just as important as selecting the right machine. Nozzles control the shape and intensity of the water spray, and using the wrong one can lead to poor cleaning performance—or even damage. In this beginner-friendly guide, we’ll break down the different pressure washer nozzle types, how they work, and when to use each one. Whether you’re a homeowner or a professional, understanding your nozzle options will help you clean more efficiently and get the most out of your washer. 

 Why Nozzles Matter 

Each pressure washer nozzle is designed to provide a specific spray angle and intensity. This determines how wide the spray pattern is and how much cleaning force is applied to the surface. Using the correct nozzle improves efficiency, conserves water, and reduces the risk of damage to delicate surfaces. 

 The Colour-Coded Nozzle System Explained 

Most pressure washer nozzles follow a universal colour-coding system. Here’s what each one means: 

🔴 Red Nozzle – 0° (High Pressure) 

• Produces a narrow, concentrated stream 

• Best for tough stains on metal or concrete 

• Use with caution—can damage soft surfaces 

🟠 Yellow Nozzle – 15° (Medium-High Pressure) 

• Strong spray for heavy-duty cleaning 

• Ideal for removing paint, mildew, or oil 

• Great for commercial surfaces and driveways 

🟢 Green Nozzle – 25° (Medium Pressure) 

• Most versatile nozzle 

• Suitable for general-purpose cleaning on patios, furniture, and vehicles 

🔵 White Nozzle – 40° (Low Pressure) 

• Wide spray pattern 

• Safe for delicate surfaces like glass, cars, and outdoor furniture 

⚪ Black Nozzle – Soap Nozzle 

• Low-pressure nozzle used to apply detergents and soap 

• Essential for pre-treatment before rinsing with higher pressure 

 Turbo or Rotary Nozzles 

Turbo nozzles combine the force of a 0° nozzle with the coverage of a wider spray. They rotate at high speed for deeper cleaning and are ideal for: 

• Cleaning concrete and masonry 

• Removing stubborn grime from construction equipment 

• Industrial applications where power and coverage are both important 

 When to Use Which Nozzle 

 Tips for Using Pressure Washer Nozzles Safely 

• Always start with a wider angle (e.g., white or green) before testing a narrow spray. 

• Avoid close-range spraying on painted or soft surfaces. 

• Use the soap nozzle only with appropriate cleaning agents. 

• Replace worn or damaged nozzles to maintain proper pressure and performance.
