Choosing the right pressure washer nozzle boils down to three key factors: task intensity, surface material, and your washer’s PSI. For heavy-duty jobs like removing rust or grease, opt for a 0° (red) or 15° (yellow) nozzle—high pressure, narrow spray. Medium-duty tasks (siding, driveways) call for a 25° (green) nozzle, balancing pressure and coverage. Light-duty cleaning (windows, patio furniture) needs a 40° (white) nozzle to avoid damage. For soap application, use a black low-pressure nozzle. Also, match the nozzle to your washer’s PSI: high-PSI washers (3000+) work best with narrow-angle nozzles, while low-PSI models (1500-2000) need wider angles for effective cleaning. Ignoring these factors leads to wasted time or ruined surfaces—take 30 seconds to assess before you spray. Click here to know more.
