Pressure washer nozzles are attachments that can greatly enhance your cleaning experience by controlling the flow of water from your pressure washer and compressing it in certain degrees to create the proper amount of pressure needed to clean a certain surface. The pressure washer itself is an efficient cleaning tool. A pressure washer user with nozzles becomes a powerful all-cleaning machine.
4 Nozzles (0-degree, 15-degree, 25-degree, 40-degree) are almost always included with the pressure washer upon delivery or purchase and are usually color coded. It is important to know the proper use for each nozzle as to avoid stripping the faint of your car with a 0-degree nozzle or spending an hour trying to wash away the piece of gum with a 40-degree nozzle. In this article, we shall define each nozzle and define the cleaning jobs that each are best suited for.
Types of Common Nozzles
1. 0-degree/Red Nozzle
This is for maximum pressure output. This nozzle is used for the highly concentrated, very stubborn stains and caked mud. The water jet hits the surface directly and takes up the surface are of a quarter coin. This nozzle is used rarely as it is often too powerful for most surfaces. It also covers a limited surface area so thus not very suitable for general cleaning.
2. 15-degree/Yellow Nozzle
This nozzle is primarily used to strip paint or prepare a surface for painting. It is also powerful enough to wash away unyielding mud and dirt. It jets out a spray larger than that of the 0-degree nozzle. Note that the 15-degree nozzle is still quit powerful and should be used with great caution when cleaning.
3. 25-degree/Green Nozzle
The most common nozzle used for all around general cleaning. Great for vehicles, driveways, and patio furnitures, the 25-degree nozzle creates a larger sheet of water that cleans a wider surface area.
4. 40-degree/White Nozzle
The gentlest of all the nozzles. It is used mainly for fragile surfaces like windows and blinds. This nozzle is also great for the watering of plants better than a garden hose as it is not strong enough to damage them.
There are also other types of nozzles used for cleaning that aid you in different ways:
1. Turbo Nozzle
This nozzle combines the force of the 0-degree nozzle with the spray area of the 25-degree nozzle in a rotating cone shape water jet. It can do all the cleaning of a 0-degree nozzle but can cover a larger surface area. Like the 0-degree nozzle though, you need to exercise some caution when using this nozzle as it can also do damage or cause any unwanted effects to the surface being cleaned.
2. Adjustable Nozzle
A nozzle that incorporates all the other nozzles into one. You can select the degree of nozzle you want buy turning or swisting the nozzle itself. This highly convenient and easier to use. (imagine the adjustable knob on a gardening hose)
3. Soap/ Black Nozzle
This nozzle is 65 degrees and has a larger orifice. This nozzle is used to pull detergent for the pressure washer’s detergent tank and ejects it out as soap. The soap nozzle allows you to apply soap on the surface your cleaning making for a more spotless finish.
Things to Remember
- Maintain a certain distance when starting out with a pressure washer and nozzles. Do not get too close as the water is sprayed at greater velocities as the surface being cleaned gets nearer to the nozzle. Never hold the nozzle closer than 6 inches to the finishing when washing your car.
- Be sure to start with a weaker nozzle and work your way up depending on the results. Do not jump to the 0- or the 15-degree nozzle right away.
- Always start on a small, inconspicuous area or the object being cleaned. Wash the surface for a few moments and stop to check for any damage, dents, or if the cleaning was effective.
- If you find a stain or dirt thats holding fast, before switching to a stronger nozzle, slowly move closer to the surface and aim at the dirt directly with the nozzle.
- Clean your nozzles regularly before and after use. Use a pin to clear the nozzle before attachment.
- Nozzles can give a flow of water that can reach a rating of 3000-4000 psi. Water at this velocity can tear flesh from bone and send debris broken off the surface being cleaned flying out at great speeds. Always wear protective gloves, goggles, and footwear when operating a pressure washer. Keep away from pets and children.
