Oil and grease stains are in a different category to general dirt and grime. They soak into concrete and paving quickly, bond with the surface, and standard pressure washing alone won’t shift them. If you’ve tried blasting an oil stain with a hose or a consumer pressure washer and watched it smear rather than disappear — that’s exactly why.
Proper oil and grease stain removal needs the right degreaser applied correctly before any pressure washing begins. We do this every week across the Central Coast and the results are consistently strong, even on stains that have been sitting for a long time.
The most common culprits we deal with on Central Coast properties:
Old stains are harder than fresh ones, but even stains that have been sitting for months or years often respond well to the right treatment. We’ll give you an honest assessment of what’s achievable before we start.
This is where the process matters. There’s a right way to do it and a wrong way.
The wrong way is to hit it straight with a pressure washer. High pressure can spread the oil further into the surrounding surface and push it deeper into the pores of the concrete — making the stain larger and harder to treat afterward.
The right way is to apply a commercial-grade alkaline degreaser directly to the stain first and give it time to break down the oil at a molecular level. Once the degreaser has done its job, we agitate the surface and then pressure wash it away. On older or deeper stains, a second application may be needed.
We carry professional degreasers that are stronger and more effective than anything available in a hardware store, and we know how long to leave them to work for the best result.
Oil and grease stains turn up on all kinds of surfaces. We treat them on:
Some porous surfaces like unsealed sandstone absorb oil very deeply and may not come out completely. We’ll be straight with you about what’s realistic for your specific surface before any work starts.
This is an area where we’d rather set honest expectations than oversell.
Fresh oil stains — anything up to a few weeks old — usually come out very well. The oil hasn’t had time to fully cure into the surface and the degreaser breaks it down effectively.
Older stains, particularly on unsealed concrete that’s been absorbing oil for months or years, will typically lighten significantly but may not disappear entirely. The improvement is usually dramatic — enough that the stain is no longer noticeable from a normal viewing distance — but a shadow can sometimes remain on very old or very heavy staining.
We’d rather tell you that upfront than have you expect perfection and be disappointed.

Most residential oil stain removal jobs come in between $150 and $400 depending on the number of stains, their size, age, and the surface type. Larger commercial jobs are quoted separately.
If you’re having a full driveway or patio clean done at the same time, stain treatment is bundled into the overall job — the most cost-effective way to get everything sorted in one visit.
We quote upfront. No surprises on the day.
Often yes, to a significant degree. Very old stains on unsealed concrete may not disappear entirely, but the improvement is usually substantial. Send us a photo and we can give you a realistic idea of what to expect before you commit to anything.
No — when applied correctly, the degreaser targets the oil and organic compounds in the stain without affecting the surrounding surface. We test on a small inconspicuous area first on sensitive surfaces like sandstone or natural stone.
Yes. The degreasers we use are biodegradable and compliant with Australian environmental guidelines. We also manage runoff carefully to avoid anything entering stormwater drains directly.
If a car or machinery is still leaking in the same spot, the stain will return. The best long-term solution is to fix the source of the leak and consider sealing the concrete afterward to make future stains easier to clean. We can advise on sealing options after the job if that's something you're interested in.
Yes. BBQ grease and cooking fat respond well to degreaser treatment. The process is the same — pre-treatment, dwell time, agitation, and pressure washing. Patio surfaces are generally less porous than driveways so the results are often very good.
