Step-by-step: power washing concrete the right way
Test a small area first using a 40° nozzle.
Hold the wand at a consistent distance (start ~12–18 inches away).
Work in sections using slow, overlapping passes.
If using detergent, apply at low pressure, let it dwell 5–10 minutes (don’t let it dry), then rinse.
Rinse thoroughly and avoid lingering on expansion joints.
How to avoid streaks and zebra-striping
Keep your pace steady and overlap each pass.
Maintain the same distance and angle throughout.
If you stop, restart slightly behind your last pass to blend.
For large driveways, a surface cleaner attachment helps create a uniform finish.
Common mistakes to avoid
Using a 0° (red) nozzle on concrete.
Getting too close and etching the surface.
Letting detergent dry on the driveway.
Skipping oil pre-treatment.
Washing without eye protection.
When to hire a pro
If you have deep oil stains, very large areas, or you want the most even finish possible, a professional power washing service can save time and help prevent surface damage.
