Choosing the right pressure washer nozzle can be daunting, but understanding the different types and their applications is key. Nozzles are typically color-coded, with each color representing a different spray angle and pressure level. A red nozzle (0 degrees) delivers a concentrated, high-pressure stream, ideal for stubborn stains but risky for delicate surfaces. Yellow nozzles (15 degrees) offer a balance between power and coverage, suitable for general cleaning tasks.
Green nozzles (25 degrees) are versatile and can be used on a variety of surfaces, providing a wider spray pattern with moderate pressure. White nozzles (40 degrees) are the gentlest, perfect for washing cars or windows without causing damage. Soap nozzles, usually black, are designed to apply detergent at low pressure, maximizing soap coverage. Always test the nozzle on an inconspicuous area first to ensure it doesn’t damage the surface.
For house washing, a 25-degree or 40-degree nozzle is generally recommended to avoid damaging siding. When cleaning concrete, a 15-degree or 25-degree nozzle can be effective for removing dirt and grime. For delicate surfaces like wood decks, a 40-degree nozzle or a soap nozzle is the safest option. Remember to adjust the pressure setting on your pressure washer to match the nozzle and the surface you’re cleaning.
