ServiCover📌 Key Takeaway: Pressure washing a driveway averages $155-$190, or $0.25-$0.35 per square foot. Hand scrubbing stubborn stains raises the rate to $0.40-$1.25 per square foot.
Concrete vs. Asphalt
| Concrete | Asphalt | |
|---|---|---|
| Pressure tolerance | High | Lower — too much can loosen aggregate |
| Common stains | Oil, rust, tire marks, mildew | Oil, fluids |
| Sealing after washing | Recommended periodically | Sealcoating recommended periodically |
Stain Treatments
- Oil and grease — degreasers plus hot water (power washing)
- Rust — specialized rust removers; pressure alone rarely works
- Mildew and algae — cleaning solutions before rinsing
- Tire marks — degreaser and surface cleaner
Why Seal After Cleaning
A clean driveway is the ideal base for sealer, which helps protect concrete from water penetration, freeze-thaw damage and staining — especially in areas where winter de-icers are used. See our de-icing guide for protecting concrete in winter.
Using a Surface Cleaner
Pros often use a rotary surface cleaner attachment on flatwork. It cleans evenly and avoids the "zebra stripes" a handheld wand can leave.
Frequently Asked Questions
How often should I pressure wash my driveway?
Once a year is common, often in spring to remove winter salt and grime.
Will pressure washing remove all oil stains?
Fresh stains respond well; old, deep stains may lighten but not disappear completely.
