Choosing the right pressure washer nozzle can be daunting, but understanding the different types is key. Nozzles are color-coded to indicate their spray pattern and pressure intensity. A red nozzle (0 degrees) delivers a concentrated, powerful stream, ideal for stubborn stains but risky for delicate surfaces. A yellow nozzle (15 degrees) offers a more moderate spray, suitable for general cleaning tasks.
The green nozzle (25 degrees) is a versatile option for washing cars and fences, providing a wider spray with less intensity. The white nozzle (40 degrees) is the gentlest, perfect for rinsing and light cleaning. Finally, the black nozzle is a soap nozzle, designed for applying detergents at low pressure. Always start with a wider angle nozzle and gradually increase the pressure as needed to avoid damage.
Consider the surface you’re cleaning when selecting a nozzle. For concrete driveways, a 15-degree or 25-degree nozzle may be appropriate, while siding requires a 40-degree or soap nozzle to prevent damage. Experiment with different nozzles on a small, inconspicuous area first to ensure they won’t harm the surface. Regular maintenance, such as cleaning the nozzles with a nozzle cleaning tool, will also help maintain optimal performance and prevent clogs.
