It’s important to know the difference between the different pressure washer nozzles so you can ensure you are using the correct nozzle for the specific job. By using the wrong nozzle, you can either damage whatever item you are pressure washing or it simply will be an ineffective cleaning. Learn more about the different nozzles below.

Red Nozzle (0-degrees) – Maximum Blast

This nozzle delivers a small stream of water. It is used for removing tough stains and dirt from concrete and/or metal. This nozzle does not have a wide spray, it hits the surface in one direct spot. The red nozzle should not be used on wood or siding because it is too strong and powerful and can end up damaging the surface of those materials. It tends to take longer to clean areas because it sprays little sections at a time. 

Yellow Nozzle (15-degrees) – Medium Blast

This nozzle is used for removing items like dirt, mildew or paint on most surfaces. This nozzle had a wide water spray and hit the surface at a lower pressure.

Green Nozzle (25-degrees) – Gentle Blast

This nozzle should be used to sweep away dirt, mud, leaves from decks, driveways and sidewalks. It is also great for cleaning boats, cars, patio furniture and driveways because of its wider spray (the green nozzle has an even wider water spray than the yellow nozzle). 

White Nozzle (40-degrees) – Minimum Blast

This nozzle has the lowest and softest spray of the bunch. It is great for fragile surfaces like windows and/or blinds.

Black Nozzle

This nozzle is a low pressure detergent nozzle. It is used when detergents are applied. 

So when trying to determine the best pressure washer nozzle, ask yourself these 4 questions:

1. Determine what surface you are looking to power wash and go through the list above to see which nozzle best fits that job.
2. Make sure to start spraying at a distance from an object. 
3. Always test on small (less fragile) areas to make sure everything is coming out smoothly. 
4. You can always contact us (via phone or email) to ask us!
