Types of Nozzle Colors
Most pressure washers in the market are made for various cleaning uses and applications, such as car washing, concrete, home exteriors, or deck cleaning.
While pressure washing cars are quicker, more thorough, and more effective than the manual hand-wipe, rinse, and dry process, it needs to be done with a good understanding of how the device works.
Otherwise, using the wrong nozzle for pressure washing car can yield costly results.
So, let’s explore further why you should use the right nozzle color tip to power wash your car.
Generally, most pressure washers come with an array of nozzle tips, and the most standard color-coded tips are the following;
- Red tip – (for maximum concentrated and pressurized water blasting) also known as the zero-degree tip shoots a straight high-pressure stream of water with a steady flow.
This nozzle tip is commonly used for concrete and hard metal surfaces to remove rust, caked mud, grime or tough grease.
However, while this nozzle type maintains a strong jet, the water pressure is concentrated on a small area and could cause significant damage to paint or dent the car body metal.
As such, this nozzle tip should not be appropriate on thin or softer surfaces such as wood, siding materials or cars.
- Yellow tip – (for medium stripping) also known as the 15-degree nozzle tip is primarily used for cleaning and stripping surfaces in preparation for painting.
This nozzle tip is also used for removing tough caked mud and dirt that collects on the underside of heavy-duty 4 x 4 trucks and semis, as well as thick grime on home exterior walls and for deck cleaning.
The yellow tip nozzle is also not recommended for use on wood and thin-sheet metals.
- Green tip – (for car and general outdoor, as well as household cleaning) also known as the 25-degree nozzle tip and one of the recommended pressure washer tip for cars.
The green pressure washer tip is by far the most common nozzle type used regularly for car washing, cleaning driveways, garden or patio furniture, and boats.
The nozzle tip creates a wider sheet of water jet stream that distributes lower pressure to a wider area to make for fast and easy cleaning.
- White tip – (for minimum spray cleaning and home interior cleaning) also known as the 40-degree pressure washer nozzle, is ideal for using alternately with the green tip for safe pressure washing of cars.
Since this nozzle tip delivers low water jet pressure over a wider surface area, it can also be good for indoor cleanings such as on glass windows, wall tiles, and blinds – particularly on fragile surfaces.
- Black tip – (soap application nozzle) also known as the 65-degree nozzle and can be utilized optionally for car washing.
This nozzle type delivers the widest spray over a large surface and can only muster enough water pressure for soap applicators and spray it onto a surface for cleaning.
The black nozzle color tip for pressure washing your car can also be proper for general-purpose cleaning.
- Special nozzles – (special use applications) are primarily adjustable hose nozzles that offer several options for special cleaning or use cases.
Among the common features available for these nozzle types are variable or adjustable streams, rotary or turbo spray, and foam cannon spray, just to name a few.
This hose nozzle type is usually sold separately from the pressure washer unit.
