A pressure washer nozzle is a very important component of your pressure washer. Most gas units - and some electric models - come with a color coded pressure washer nozzle set.
To get the job done right, you need to match the color of the nozzle to your specific cleaning project. If you use the wrong nozzle, you may not get enough cleaning power - or you could get too much power and damage the surface of the material you're trying to clean!
Follow my pro tips, below, to match the correct color to the cleaning or paint stripping job you have. You save time & you'll avoid damaging your surface!
Each pressure washer nozzle color indicates the degree of the angle, or the size of the spray fan, of the pressurized water.
Remember: the wider the angle or spray fan, the less cleaning power. But the smaller the degree or spray fan, the more intense the power.
Here's how & where to use each color nozzle:
White - gives you a 40 degree spray angle and it's great for general washing projects that have more sensitive surfaces like: siding, stucco, antique bricks, etc.
Green - is a 25 degree spray angle and is not always included with a new power washer unit. A green spray tip is slightly more powerful than a white one and is used for general cleaning like cleaning decks, walkway, patios and outdoor furniture.
Yellow - provides a 15 degree spray angle which is very powerful. It's much more powerful than the white and green tips. You should only use this tip if you need more powerful cleaning than the white or green tip can offer. If you have a tough job like a stained garage floor or oil stains, the yellow tip is a good choice. And yellow can also be used for paint stripping.
Red - this is the 0 degree spray tip which is extremely powerful! Seriously, red can very easily gouge wood, cement, asphalt, etc. Remember to always experiment with the cleaning power of the white, green and yellow spray tips before even thinking about switching to red.
Black - this is a low pressure nozzle that has a 65 degree pattern that's used for soap or chemical injection. If you want to apply detergents or chemicals to a surface, this is the spray tip you need. After you apply the soap or chemicals with the more gentle black tip, change to a white, green, yellow or red tip, to start deep cleaning.
Eventually, spray tips wear out. Or get lost. But replacing them is fairly easy. You can usually find them at your local hardware store. Or at your big box store. And don't forget that there are lots of online stores that sell all type of pressure washer parts - including replacement nozzles.
