Pressure washing a driveway works best with a rotary surface cleaner on the lowest setting that moves the dirt. Sweep and weed first, pre-treat oil and algae, clean in overlapping passes, rinse the run-off to a drain and re-sand block paving joints once dry. Avoid frosty days and narrow jets, which etch concrete.
Pressure washing a driveway is one of the most satisfying jobs at home. Strip after strip of grey turns back into clean concrete or bright paving, and the whole front of the house looks cared for again. It's also easy to get wrong: stripes, etched concrete, blasted-out joints and oil stains that spread rather than lift. This guide walks through the kit, the method and the finishing touches so the result lasts through the wet months.
Before you start: know your driveway
| Driveway type | Can you pressure wash it? | Best approach |
|---|---|---|
| Poured concrete | Yes | Rotary surface cleaner on a medium setting, pre-treat stains, rinse well |
| Block paving | Yes, with care | Lower setting, angle the lance, then re-sand the joints and consider sealing |
| Tarmac or asphalt | Gently | Low pressure only; high pressure can loosen the surface stones |
| Resin-bound | Gently | Low pressure and a wide fan; check the installer's care advice |
| Gravel | No | Rake, weed and top up instead |
| Natural stone setts | Carefully | Low pressure and stone-safe cleaners; avoid acidic products |
The kit that makes the difference
- A pressure washer suited to outdoor hard surfaces (light domestic models struggle on large drives)
- A rotary surface cleaner or patio attachment, which stops the stripy finish you get with a single lance
- A wide fan nozzle for edges and rinsing
- A driveway or concrete cleaner, plus a degreaser for oil marks
- A stiff broom and a weeding knife
- Kiln-dried sand for block paving joints
- Safety glasses, gloves and sturdy closed shoes
A rotary surface cleaner is the single upgrade that changes the job. It spins the spray inside a hood, so you get an even clean, less splashback and far fewer lines across the drive.
Pressure washing a driveway: the method
- Clear the drive. Move cars, bins and anything loose, and sweep up leaves and grit.
- Weed and scrape the joints. Lifting weeds first stops them being chopped into the gaps and regrowing.
- Pre-treat stains. Apply degreaser to oil marks and a driveway cleaner to green areas, and give them the time stated on the label.
- Test a small area. Start on the lowest setting in a corner and increase only if the dirt isn't moving.
- Clean in overlapping sections. Work across the drive in steady passes, overlapping each pass a little, from the top of the slope downwards.
- Do the edges. Switch to a fan nozzle for the borders, steps and the area by the garage door.
- Rinse the slurry away. Flush dirty water towards a drain or the road gutter, not onto lawns or into airbricks.
- Let it dry and check. Patchy areas show once dry; spot-treat and go over them again.
- Finish block paving. Brush kiln-dried sand into the joints and consider a sealer once the surface is completely dry.
How to avoid stripes and etching
Stripes, also called zebra marks, happen when the nozzle is held at different distances or the passes don't overlap. Etching happens when a narrow jet sits on one spot. The fixes are simple: keep the lance moving, keep a steady distance, use a surface cleaner on the main area and never use a pencil jet on concrete or paving. If you can see the surface roughening, stop and turn the pressure down.
Oil, rust and tyre marks
Oil stains are the hardest to shift because oil soaks into concrete. Blot fresh spills with cat litter or sawdust, then use a degreaser and a stiff brush before you pressure wash. Older stains may need several treatments and will often fade rather than disappear completely. Rust marks from garden furniture or tools need a rust remover made for concrete or stone, used exactly as directed. Black tyre marks usually lift with a degreaser and a scrub.
Re-sanding and sealing block paving
Pressure washing removes some of the jointing sand between blocks, which is what holds them tight and keeps weeds out. Once the drive is fully dry, sweep kiln-dried sand across the surface and into the joints, then sweep off the excess. Repeat if the joints settle. A paving sealer can help bind the sand, deepen the colour and make future cleaning easier, but it needs a dry forecast and a completely dry surface to work.
Why autumn is a good time to do it
- Moss and algae are easier to remove before winter rain sets them in.
- Clean surfaces drain better, so less water sits on the drive and freezes.
- Leaves and mud from autumn stain paving if they're left over winter.
- Sealers and jointing sand need dry weather, which is easier to find in early autumn than in midwinter.
Avoid pressure washing when a frost is forecast. Water forced into joints and small cracks can freeze, expand and do the very damage you're trying to prevent. If your patio needs attention too, my step-by-step guide on how to clean a patio covers the gentler methods for sandstone and porcelain.
Staying safe
- Never point the lance at people, pets, windows or your own feet.
- Keep electrics dry, use an outdoor socket with RCD protection and keep the cable away from the spray.
- Wear eye protection, because grit and chips fly off at speed.
- Watch your footing on wet, freshly cleaned surfaces, which can be slippery.
- Keep children and pets indoors while you work and until cleaners have been rinsed away.
Hire a pro or do it yourself?
Doing it yourself suits most concrete and block paving drives if you're happy to spend a few hours on it. A professional is worth considering for very large drives, resin or natural stone surfaces, heavy oil staining, or if you want the drive re-sanded and sealed in one visit. Ask about the equipment they use, how they protect the joints and whether they'll clean up the run-off. A tidy drive also sets up the front of the house for winter, and my guide to winter-proofing your home covers the rest of the outside jobs.
Choosing a pressure washer for a driveway
If you're buying a machine mainly for the drive, look past the headline pressure number. Flow rate matters just as much, because it's the volume of water that carries the dirt away. A machine that handles a rotary surface cleaner well will save you far more time than one with a slightly higher pressure rating.
- Check the attachment fits. Not every surface cleaner works with every brand, so confirm compatibility before you buy.
- Look at hose and cable length. A long hose means you're not dragging the machine across wet ground.
- Think about storage. A compact upright model with wheels is easier to keep in a garage or shed.
- Consider noise and weight if you'll be carrying it up steps.
- Read the care guide. Draining the machine before frost protects the pump over winter.
How long it takes and how often to do it
A typical single-car drive takes a morning once you include clearing, pre-treating, cleaning, rinsing and re-sanding. A double drive with heavy moss can take most of a day. For most homes, a deep clean once a year in early autumn plus a quick rinse in spring is plenty. Shaded drives under trees may need attention more often, because they stay damp and grow algae faster.

Keeping the drive clean afterwards
Sweep regularly, deal with oil spills straight away, keep gutters and drains clear, and pull weeds while they're small. A light wash once or twice a year is usually enough once the hard work is done.

Frequently asked questions
What pressure should I use to clean a driveway?
Start on the lowest setting and increase only if the dirt isn't moving. Concrete can take more than block paving, tarmac or resin, which need a gentle approach.
Do I need a surface cleaner attachment?
It isn't essential, but a rotary surface cleaner gives a far more even finish, cuts down on stripes and saves time on large areas.
How do you get oil stains off a driveway?
Blot fresh spills, then apply a degreaser and scrub before you pressure wash. Older stains may need several treatments and may fade rather than vanish.
Should I re-sand block paving after pressure washing?
Yes. Once the drive is dry, brush kiln-dried sand into the joints to lock the blocks and help keep weeds out.
Can you pressure wash a driveway in winter?
It's best avoided when frost is forecast, because water in the joints and cracks can freeze and cause damage.
