How to clean a driveway with oil stains properly

Oil stains are stubborn. Whether it's a slow drip from an older car, a one-off spill during an oil change, or years of build-up on a busy driveway, they sink into the surface quickly and bond hard. But knowing how to clean a driveway with oil stains — and doing it in the right order — makes a real difference to the result.

Here's a straightforward guide to what actually works, broken down by surface type.

Why oil stains are so hard to shift

Oil is hydrophobic — it repels water — so simply hosing down your driveway pushes it around rather than lifting it. Worse, motor oil, hydraulic fluid and diesel all contain compounds that penetrate porous surfaces like concrete, tarmac and natural stone almost immediately. The longer you leave them, the deeper they go.

Fresh stains are always easier to tackle than old ones. If you've just noticed a spill, act fast.

What to do with a fresh oil spill

For a spill that's happened in the last few hours:

1. Absorb as much as possible first. Cover the stain generously with cat litter, dry sand, or sawdust. Leave it for at least 30 minutes — longer if you can.
2. Sweep it up and dispose of it. Don't wash it away at this stage.
3. Apply a degreaser. A dedicated traffic-film remover or alkaline degreaser (widely available at motor factors) is far more effective than washing-up liquid. Leave it to dwell for 10–15 minutes.
4. Agitate with a stiff brush. Work the degreaser into the surface in circular motions.
5. Rinse thoroughly. A pressure washer at this stage will give you a much cleaner result than a garden hose.

Done quickly, this approach can remove a fresh stain almost completely.

Treating old or set-in oil stains

Older stains need a bit more patience. The same process applies, but you'll likely need to repeat it two or three times — and the result won't always be a perfect match with the surrounding surface.

Poultice method for porous surfaces

On natural stone, concrete slabs or sandstone, a poultice can draw oil back out of the material rather than simply treating the surface. Mix fuller's earth, baking soda, or talcum powder with a solvent (acetone or white spirit work well) into a thick paste. Apply it over the stain, cover loosely with cling film, and leave it for 24–48 hours. The paste absorbs the oil as it dries. Scrape it off, then rinse and degrease as above.

This is slower, but it's often the only approach that genuinely shifts deep stains on porous stone.

Pressure washing alone won't do it

A lot of people reach for the pressure washer first. It's useful — but on its own, it won't remove oil. You need to break the bond with a chemical treatment before the water can flush it away. Pressure washing after degreasing, however, is very effective and speeds up the whole process considerably.

Does the surface type change what you should use?

Yes — and this matters.

• Concrete driveways: Alkaline degreasers work well. Avoid strong acids, which can etch the surface.
• Block paving: Degrease first, then pressure wash. Be careful not to disturb the kiln-dried sand in the joints — you may need to top it up afterwards.
• Tarmac/asphalt: Avoid solvent-based products here. Solvents can soften and damage tarmac. Stick to water-based degreasers.
• Resin-bound driveways: These are more delicate. Use a mild degreaser and low-pressure rinsing — aggressive chemicals or high pressure can damage the surface.
• Natural stone and Indian sandstone: Use pH-neutral or alkaline cleaners. Acid-based products will damage the stone.

If you're not sure what surface you have or what's safe to use, it's worth getting advice before you start.

When DIY reaches its limit

Some oil stains — particularly those that have been sitting for months or years, or stains from diesel, hydraulic fluid or transmission fluid — don't respond well to DIY treatment. They've penetrated too deep, and repeated scrubbing can just spread the contamination.

In these cases, professional hot-water pressure washing combined with commercial-grade degreasers gets results that aren't achievable with consumer products. We carry specialist treatments for oil contamination and use the right equipment for each surface type, whether that's a driveway in North Hykeham or a forecourt in Branston.

Will the stain come out completely?

Honestly — sometimes, yes. Sometimes, no. A fresh, shallow stain on a smooth concrete driveway can come out completely. An old, deep stain on highly porous sandstone may always leave a faint shadow.

What a proper clean will always do, though, is make the stain significantly less visible and stop it spreading. In many cases, sealing the driveway after cleaning helps prevent future oil from penetrating as deeply — worth considering if staining is a regular problem.
