What Is a Zero-Degree Nozzle?
A zero-degree pressure washer nozzle (often marked in red) produces a very narrow, concentrated jet of water. Because the spray pattern is so tight, it delivers the highest impact pressure of any common nozzle type. This makes it extremely effective on stubborn grime — but it also makes it the most likely to cause surface damage if used incorrectly.
Why 0° Nozzles Are So Powerful
Most nozzles spread water out in a fan shape (15°, 25°, 40°). A 0° nozzle does the opposite: it focuses the water into a single stream. That concentration increases cutting power, which is why a zero-degree tip can strip paint, etch surfaces, and dig into softer materials.
Best Surfaces to Use a Zero-Degree Tip On
Zero-degree nozzles are best reserved for hard, durable surfaces where a narrow stream is needed. Even then, you should test a small area first and keep the spray moving.
- Heavily stained concrete (spot cleaning only)
- Very tough grime on thick stone paving (with caution)
- Rust removal on heavy-duty metal surfaces (where appropriate)
- Deep cleaning in tight corners (short bursts only)

Surfaces You Should Never Use It On
A zero-degree nozzle can cause immediate, permanent damage on many common household materials. Avoid using it on:
- Wood decking (splintering and gouging risk)
- Painted surfaces (strips paint fast)
- Car paint, trims, seals, and tyres
- Soft stone, mortar, grout lines, and older paving joints
- Outdoor furniture, plastics, and composite materials
Zero-Degree vs Turbo Nozzle: What’s the Difference?
Many people confuse a turbo nozzle with a zero-degree tip. A turbo nozzle creates a rotating spray pattern that delivers high cleaning power while covering more area. A zero-degree nozzle delivers a static, pinpoint jet. In most home cleaning situations, a turbo nozzle is the safer high-power option.
Choosing the Right PSI for Safe Use
Safe use depends on your pressure washer’s PSI and how close you hold the nozzle to the surface. Higher PSI washers increase damage risk significantly. As a practical rule, keep your distance and increase power only if the surface can handle it.
- Lower PSI machines: still risky, but easier to control for short bursts
- Higher PSI machines: use with extreme caution; damage can happen instantly
- Always test first: start far back and move closer slowly if needed
Safety Tips for Beginners
If you decide to use a 0° nozzle, treat it like a precision tool. These safety habits reduce risk:
- Wear eye protection and closed footwear
- Never point the nozzle at people, pets, or glass
- Keep the jet moving — do not hold it in one spot
- Start at a safe distance and step in gradually
- Use short bursts for spot cleaning, not full-surface passes
- Switch to a wider nozzle (15°/25°) as soon as the dirt breaks up

FAQs About Zero-Degree Pressure Washer Nozzles
What does a zero-degree pressure washer nozzle do?
It produces a narrow, concentrated jet that delivers maximum impact pressure, making it effective for spot cleaning — but more likely to cause damage than wider spray tips.
Can a 0-degree nozzle damage concrete or decking?
Yes. On concrete it can etch lines or create visible marks if held too close. On decking, it can gouge, strip, and splinter the wood. Always test first and use the safest nozzle that works.
Is a turbo nozzle safer than a zero-degree nozzle?
In most cases, yes. Turbo nozzles provide strong cleaning power while spreading the force over a rotating pattern. A zero-degree nozzle concentrates all force into one point, which increases damage risk.
