Remove Oil Stains From Asphalt

The Problem

Petroleum spills on asphalt are common in oilfield yards, lease roads, equipment staging areas, truck parking lots, and industrial facilities. Diesel, motor oil, and hydraulic fluids penetrate the surface and bond into the bitumen binder, leaving dark stains and ongoing odor issues.

Because asphalt itself is petroleum-based, traditional degreasers and absorbents often fail to fully release embedded contamination. Solvent-based cleaners may temporarily wash the surface but can create safety risks and do not address petroleum trapped within the asphalt structure.

The Solution

Petro Buster® emulsifies petroleum contamination and weakens its bond to the asphalt surface. When diluted and scrubbed into the affected area, it lifts embedded hydrocarbons so they can be rinsed away or naturally dispersed with water.

As the product penetrates and works through the contaminated area, it allows the petroleum residue to break free from the bitumen. Heavy stains will often darken temporarily during treatment as it bring the tar up like new temporarily, then fade back to normal appearance over time with sun exposure and weathering.

This provides a safer, practical method for treating petroleum spills on asphalt without relying on harsh solvent systems.

It is used by professionals and property owners for petroleum remediation across North America.

Directions – Asphalt

1. Verify amount needed by estimating how much water would cover your stain(s).
2. Dilute 1 part Petro Buster with 4 parts water.
3. Pour liberally on to the Oil stain on Asphalt.
4. Scrub firmly with stiff bristle brush until it starts foaming.
5. Keep scrubbing until foam turns brown. That is the Oil being removed from the Asphalt.
6. Rinse away with fresh water.
7. Let dry and view area and if there is any stain left, repeat steps 1 to 6 above.
8. You should see the more difficult stains fade away over a few days. Rain and Sun will help once Petro Buster has been introduced to the Oil and weakened its bond to the Asphalt.
9. Asphalt is made with Petroleum tar called Bitumen and Petro Buster will make it come up like new and very black during the process of extracting the oil from the tar. That area may look very black temporarily and will fade back to normal with sun exposure and over time will match the remainder of your driveway without the stain.
