Asphalt driveways are tough and low maintenance, but they’re not stain proof. Over time, oil, rust, mold, and even paint can leave unsightly marks that hurt curb appeal. The good news? Most tough stains on asphalt can be removed with the right cleaning methods and a little elbow grease. Here’s a how to guide on how to remove common stains from your asphalt driveway.
1. Oil and Grease Stains
Oil and automotive fluids are the most common and toughest stains. If left untreated they can weaken the asphalt over time.
How to remove:
- Step 1: Blot up any excess oil with a paper towel or cloth.
- Step 2: Sprinkle kitty litter, baking soda or cornstarch over the stain to absorb remaining oil. Let it sit for 1-2 hours then sweep it up.
- Step 3: Use a degreaser or dish soap mixed with warm water and scrub the stain with a stiff bristle brush.
- Step 4: Rinse with a garden hose or pressure washer.
Repeat if necessary. For old set in stains consider a commercial asphalt cleaner.
2. Rust Stains
Rust can leave reddish brown stains, often from metal furniture, tools or vehicles.
How to remove:
- Mix lemon juice or white vinegar with water and pour over the stain.
- Let it sit for 10-15 minutes to break down the rust.
- Scrub with a brush and rinse with water.
For tough stains a rust remover for concrete and asphalt can help — just make sure it’s asphalt safe.
3. Mold and Mildew
Shady or damp areas of your driveway may develop mold or algae over time leaving green or black stains.
How to remove:
- Mix one part bleach with three parts water in a bucket.
- Apply to the affected area with a mop or garden sprayer.
- Let it sit for 10-15 minutes then scrub with a brush.
- Rinse with a hose or pressure washer.
Wear gloves and eye protection when working with bleach and avoid letting it run into your lawn or garden.
4. Paint or Chemical SpillsPaint and certain household chemicals can discolor or damage asphalt if not cleaned right away.
How to remove:
- For wet paint absorb excess with rags and use a paint thinner or mineral spirits (check for asphalt compatibility).
- For dried paint use a plastic scraper to lift it off then scrub with a degreaser.
- Don’t use anything too abrasive that can damage the asphalt surface.
5. Tire Marks
Tire scuffs or burnouts can leave black marks on your driveway.
How to remove:
- Use a degreaser or simple green cleaner mixed with water.
- Scrub with a stiff brush and rinse.
Pro Tip: Seal Your Asphalt Driveway
Once you’ve removed the stains consider sealcoating your asphalt driveway. A fresh seal not only looks good but makes it easier to clean and protects against future stains and weathering.

Removing tough stains from your asphalt driveway doesn’t have to be a big job. With the right tools and techniques you can keep your driveway clean and maintained all year round. Whether you’re dealing with oil, rust or mildew regular cleaning and maintenance can go a long way in preserving your asphalt surface.
