How to remove oil stains from a driveway

Oil is the most-searched driveway problem in the UK by a distance, and most of the advice online is either useless or actively damaging. Here is what actually works, broken down by how old the stain is and what your drive is made of.

How do you get fresh oil off a driveway?

Absorb before you scrub. Anything still wet will spread under a brush and turn one stain into a larger, fainter one.

• 1. Soak it up

  Cover the whole patch in cheap clay cat litter, baking soda or sand. Tread it in gently. Leave it 24 hours — longer if the spill was heavy.

• 2. Sweep and bin it

  Sweep the absorbent up and put it in the bin, not down a drain. It is now contaminated.

• 3. Degrease

  Apply a proper alkaline degreaser, or dishwasher powder mixed into a paste with hot water. Leave 15–30 minutes. Do not let it dry out.

• 4. Agitate and rinse

  Scrub with a stiff brush, then rinse with hot water. Repeat rather than escalating to something harsher.

How do you remove an oil stain that has been there for years?

Old oil has migrated into the pores of the material, so a surface wash cannot reach it. You need a poultice — something that holds a solvent against the stain long enough to draw it back out.

Mix a degreaser or a proprietary poultice powder to a thick paste, spread it 5–10mm thick over the stain, and cover with cling film taped at the edges. Leave overnight. As it dries it pulls the oil up into the paste. Scrape off, rinse, and expect to repeat two or three times on a stain that is several years old.

How do you get oil off block paving specifically?

Block paving has one extra step and one extra risk. The extra step is re-sanding: any washing strong enough to shift oil also washes kiln-dried sand out of the joints, and blocks without jointing sand lose their interlock and start to move. Brush fresh kiln-dried sand in once the area has dried.

The extra risk is that a single block is replaceable. If a stain will not shift, the block can be lifted and swapped for one taken from an inconspicuous area — under where a car sits, or behind a gate. On a drive more than about ten years old that swap is far less visible than a brand-new block would be.

What should you never use on an oil stain?

• Petrol, diesel or white spirit

  They dissolve the oil and drive it deeper into the surface, and they are a genuine fire risk on a driveway. This is the single worst piece of advice in circulation.

• Bleach

  Does almost nothing to oil, kills the planting it runs into, and can discolour concrete and some natural stone.

• A pressure washer lance held close

  On block paving it strips the joints. On pattern imprinted concrete it takes the sealer and the colour layer with it. Use a wide fan or a flat-surface attachment, kept moving.

• Acid-based cleaners on limestone

  Limestone and some sandstones react with acid and will etch. Check what your surface is before reaching for a "patio cleaner".

How do you stop it happening again?

A car that drips is going to keep dripping, so deal with the car. Beyond that, a penetrating sealer on block paving or concrete slows absorption enough that a fresh spill sits on the surface long enough to be wiped up — which is the difference between a five-minute job and a poultice.

If the drive is at the end of its life anyway, resin bound and block paving handle spills very differently: resin is seamless and easier to wipe but stains more readily on pale aggregate, while block paving is more porous but lets you swap a single unit. There is more on that trade-off in our block paving versus resin comparison.
