Step-by-step: how to power wash a driveway

  • Start with a wide nozzle (40°) and test a small area.

  • Hold the wand at a consistent angle and 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 spraying directly at expansion joints for long periods.

Tips for better results

  • Use consistent strokes to avoid zebra-striping.

  • For heavy grime, make a second pass instead of increasing pressure too much.

  • Consider a surface cleaner attachment for large driveways.

  • Rinse nearby siding/garage doors after washing to remove splashback.

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, large areas, or you want uniform results fast, a professional power washing service can help avoid surface damage and save time.
