Things You'll Need
Metal putty knife
The above method is ideal for removing spray paint over spray from asphalt. If you need to remove paint splatters and drips from asphalt, use a metal putty knife instead of a wire brush.
You may be surprised how effective a pressure washer is at removing spray paint from asphalt. However, do not become too aggressive as this may cause you to accidentally remove chunks from the surface. Always begin the washer on a low setting, and gradually increase pressure.
When paint finds its way onto some surfaces, the removal process can be tricky. Certain surfaces like wood and drywall are dry and porous, qualities that lead them to soak up the adhesives in paint. Fortunately, if you need to remove spray paint from asphalt, you're in a much better position. Because asphalt is petroleum-based, it is relatively slick making it a poor surface for paint adhesion. Still, you will need to use care during the removal process, or you could damage the surface you are trying to save.
Focus concentrated water pressure on the spray paint using a pressure washer. Start the washer on its lowest setting, and slowly increase intensity being careful not to damage the asphalt.
Allow the asphalt to dry out completely.
Pour a few drops of mineral spirits on the spray paint.
Allow the mineral spirits to soak for twenty seconds.
Scrape away the remaining spray paint using a wire brush.
Rinse the surface with the pressure washer.
