Oil stains on concrete driveways are one of the most searched cleaning problems in Queensland — and one of the most misunderstood. Pressure washing alone won't remove them. The right degreaser pre-treatment will.

Oil stains on concrete driveways are a persistent problem for Queensland homeowners — engine oil, hydraulic fluid, transmission fluid and cooking oil from barbecue areas all leave dark penetrating stains that standard pressure washing simply cannot remove. This is one of the most common misunderstandings in exterior cleaning: oil is a hydrophobic compound that water pressure cannot emulsify. Only a chemical degreaser that breaks down the hydrocarbon chains in oil can release the stain from the concrete surface. Burnett 2 Bay uses professional grade alkaline degreaser pre-treatment on all oil-stained driveway surfaces before pressure cleaning — producing results a standard pressure wash cannot achieve.
Oil and water don't mix. Pressure washing an oil stain just pushes contaminated water around without removing the oil itself. Only a surfactant or alkaline degreaser that chemically breaks down the hydrocarbon compounds in oil can emulsify it and allow it to be rinsed away effectively.
Fresh oil stains respond very well to degreaser treatment. Established stains that have been in concrete for months or years are progressively harder to remove because the oil penetrates deeper over time. We give you an honest assessment of expected results when we quote.
We apply a professional grade alkaline degreaser to oil-affected areas and allow it to dwell appropriately to break down oil compounds. The area is then agitated where needed and pressure cleaned to remove the emulsified oil and degreaser. Multiple applications may be needed for established staining.
Concrete sealing after cleaning significantly reduces future oil absorption — sealed concrete is far less porous and much easier to clean if oil is spilled again.
Yes — with professional grade degreaser pre-treatment followed by pressure cleaning. Fresh stains respond very well. Long-established stains may only be partially removable.
Pressure washing without degreaser pre-treatment will not effectively remove oil stains. Degreaser treatment is essential.
Depends on the area and extent of staining. Best value as an add-on to a house wash or roof clean. Contact us for a free quote.
