Most Common Types Of Asphalt Stains And How To Remove Them

Most people who haven’t managed a pavement in the past think that since their newly paved asphalt surface is black, they can go easy on the cleaning part of their maintenance regime.

However, we have news for those first-timers – your asphalt surface can get stained! Firstly, your blacktop’s rich black color will fade to gray over time, which means stains will be all the more prominent with time unless you give it regular seal coats. Secondly, both old and new pavement can get stains.

It is essential that you remove all and any stains from your asphalt surface as soon as they appear. By staying proactive, you will maintain your asphalt pavement’s pristine condition for a long, long time. Stains ruin the aesthetic appeal of your pavement, which affects your property’s curb appeal. Also, stains damage the pavement.

Thus, it is crucial to treat the stain ASAP. Yet, there is no one-shoe-fits-all kind of solution for that. All stains are different, and so are their removal techniques. Let’s look at some common stains that you might spot on your asphalt surface and the cleaning techniques for each of them.


It is not uncommon for vehicles to leak engine oil and gasoline, but it is imperative that you immediately clean oil stains as they can cause extensive damage to an asphalt pavement if ignored.

The best way to clean up vehicle fluids is to pile cat litter, gravel, or sawdust on the spill and leave it from anywhere between a few hours to overnight, depending on how much time it takes for the oil to get soaked up by the material.

Sweep the surface once the excess oil is soaked up. Next, use a mild cleaning solution (detergent or baking soda solution), a soft bristle brush, and water to clean the remaining oil. Scrub the solution with the brush in a circular motion on the stain and leave the solution for a few minutes before washing it off.


Gas can leave an unseemly stain on your pavement and eat away at the asphalt. Therefore, you need to use the same deep-cleaning method for oil spills to remove gas stains.


Mulch dyes can leave stains on your asphalt. Rinse your surface with water, scrub a detergent or vinegar solution on the stain with a soft brush by scrubbing in circular motions, leave the cleaner on the pavement for a few minutes and give it a low-pressure wash with water.

Tire marks

Skidding or rough driving can cause tire marks to appear on your asphalt pavement. To remove them, make a mild cleaning solution by diluting dish soap with water and scrubbing it on the stain in circular motions using a soft bristle brush. Leave the solution for five minutes, and wash it off with water.


Paint is the most challenging stain to remove as the paint’s solvents tightly bind to the asphalt, and most removal methods result in discoloration of the surface and leave behind scratches. Extended exposure to paint solvent or remover can soften the asphalt. Wire brushes can damage the surface. So the best thing to do in this situation is to call an expert for safe removal.

Before attempting any asphalt cleaning project, remember one important tip – never powerwash your pavement. Always give your asphalt surface low-pressure washing because a power wash can push the stains (liquid that has penetrated into the surface) deeper into the pavement.
