Types of Pressure Washer Nozzles
There are different types of pressure nozzles, and each of these is ideal for specific types of jobs. At times, you might need to replace a nozzle while you are cleaning once you are done with the heavy cleaning, and you want to focus on specific areas to clean.
The sum of the matter is that choosing the right nozzle for the job will give you exceptional results. The pressure washer nozzles are color-coded (Red, Yellow, Green, White, and Black) for ease of recognition. Let’s take a look at the different types of pressure washer nozzles.
1) Red (0-degree) Nozzle
This type of nozzle is the smallest of all nozzles. The red nozzle is used for removing tough stains or sticky residue from surfaces. The water jet from the nozzle is highly concentrated for maximum power, and it should only be used on metal or concrete. If you use this nozzle on any other surface, such as wood, plastic, or brick, you will end up damaging the surface.
As the jet from this nozzle is the smallest in size, it is not ideal for cleaning large surfaces as it would take a lot of time to cover large areas. This nozzle is also dangerous because it offers the highest pressure rating, and Consumer Report does not recommend the use of this nozzle for pressure washing.
2) Yellow (15-degree) Nozzle
The yellow nozzle is ideal for preparing surfaces for painting or staining. The 15-degree fan spray is powerful enough to remove old paint or dirt from a surface. This type of nozzle is ideal for use on metal surfaces that need a fresh look. Avoid using this nozzle too close to the surface as the power from the jet might end up damaging the surface.
3) Green (25-degree) Nozzle
This is a common purpose nozzle that is used for cleaning most surfaces. The spray is wide, and you can use it to swipe away debris and grime that is only on the surface and not deep inside. This is not the nozzle you want to use when you want some hard cleaning, so it is ideal only for soft cleaning tasks. The wide-angle of the green nozzle gives you the ability to clean a large area quickly. You can use this nozzle to clean everything from boats to patio furniture to decks, and more.
4) White (40-degree) Nozzle
The 40-degree nozzle is white, and it is a gentle spray that is perfect for light cleaning of delicate items. If you are planning to do a light cleaning of your car, windows, or flower pots, you can use this nozzle with your pressure washer. If you have applied detergent to your vinyl siding or car, this is the perfect nozzle of wash off the soap.
5) Black (Soap) Nozzle
The black nozzle is used for applying soap on walls or siding. The nozzle has a large exit hole, which reduces the speed of the water and increases the pressure to pull soap from the tank. The widest nozzle of the bunch, the soap nozzle, has an angle of 65 degrees.
6) Turbo Nozzle
This is one of the add-on nozzles that might or might not be included with your pressure washer. This nozzle is also known as the rotary nozzle. The nozzle produces a jet of water that is equal to zero-degree nozzle, but it pulsates and spins at 5000-9000 RPM. The nozzle creates a circular pattern spray that expands to 15 degrees. If you are cleaning a large area, this can reduce the cleaning time, but this is a high-powered nozzle, and it should be used with care.
How do Pressure Washer Nozzles Work?
Pressure washer nozzles work on the simple principle that restricting the flow of water in the hose to create pressure that forces the water to come out forcefully. Some nozzles restrict more water by design, which makes the water come out with a greater force, while others spread the water in a fan shape for a variety of cleaning needs. A nozzle with a smaller exit hole will create more pressure, while a nozzle with a wide hole will create less pressure.
You might often need to switch from one nozzle to another, depending on the cleaning you are doing. If you are stripping rust from a machine, you might want to use a yellow (15-degree) nozzle. But if you are cleaning soap from a vinyl siding, a white (40-degree) nozzle would suit your needs better.
