The Definitive Guide to Removing Oil Stains From an Asphalt Driveway

So, you’ve got that dreaded dark stain on your otherwise perfect asphalt driveway. It happens to the best of us. A small, unnoticed drip from a guest's car, a little spill while topping off your own oil, or maybe a leak you’ve been meaning to get to. Whatever the cause, that ugly black spot is now the first thing you see when you pull up to your house.
Honestly, it’s more than just an eyesore. Oil stains aren’t just a cosmetic issue; they’re a sign of something that can actually damage your driveway in the long run. & it's one of those problems that feels like it should be simple to fix, but can be surprisingly stubborn.
Here’s the thing: asphalt & motor oil are basically cousins. They’re both petroleum products. This chemical similarity is why they bond so well—and why it’s such a headache to separate them. When motor oil, transmission fluid, or gasoline seeps into your driveway, it actually starts to dissolve the bitumen binder that holds the asphalt together. Over time, this makes the asphalt soft, brittle, & much more likely to crack or form potholes. What starts as a simple stain can become a structural problem.
But don't panic. You CAN get rid of it. I’ve spent a ton of time figuring out what works & what doesn’t, from old-school home remedies to heavy-duty commercial products. This guide is the culmination of all that trial & error. We’re going to cover everything you need to know to get your driveway looking clean again.

First Things First: Immediate Action for Fresh Spills

If you catch an oil spill right after it happens, you're in luck. Acting fast is the single most important thing you can do to prevent a permanent stain. The goal here is absorption. You want to pull as much of that liquid oil out of the porous asphalt as possible before it has time to set.
Grab an Absorbent—ANY Absorbent!
The most common & effective tool for this is non-clumping clay cat litter. It’s cheap, super absorbent, & easy to find. Many households already have it.
Here's the drill:
  1. Don’t wipe or rub! This will only push the oil deeper into the asphalt's pores.
  2. Generously cover the entire fresh spill with a thick layer of clay kitty litter—at least half an inch deep.
  3. Gently step or press on the kitty litter. The slight pressure helps it make better contact & absorb more oil from the surface.
  4. Let it sit. For a fresh spill, give it at least a few hours. For a really saturated spot, leaving it overnight is best.
  5. The next day, sweep up the oil-soaked litter & dispose of it properly. Remember, it's now considered hazardous waste, so don't just toss it in the regular trash. Check with your local waste management for guidelines on disposing of oily materials.
What if You Don't Have Cat Litter?
No worries. Other common household items can work in a pinch. Baking soda, cornstarch, or even sawdust can be used as an absorbent. The principle is the same: cover the spill completely, let it sit, & then sweep it up. Baking soda's fine grains can be a bit harder to sweep up from the rough asphalt surface, but it's better than letting the oil soak in.

The DIY Arsenal: Everyday Household Products That Actually Work

Okay, so you’ve soaked up the excess oil, but a dark stain remains. Or maybe you’re dealing with a stain that’s been there for a while. It’s time to move on to cleaning. Before you run to the hardware store, you might be surprised at what you already have in your garage or kitchen that can make a real difference.
We'll start with the gentlest methods first. It's always best to begin with the least aggressive approach & work your way up.

Method 1: The Dish Soap Scrub

This is your first line of attack for a reason. Dish soap (think Dawn or similar brands) is literally designed to cut through grease. It’s a surfactant, which means it helps break down oil & allows it to be washed away with water.
  • How to do it: Squirt a generous amount of dish soap directly onto the oil stain. Add a little bit of water to create a soapy, concentrated solution. Now, grab a stiff-bristled brush (not a wire one yet, that’s for later) & start scrubbing. Use some elbow grease & work in a circular motion. Let the soap mixture sit on the stain for at least 15-30 minutes, then rinse thoroughly with a hose. You might need to repeat this a couple of times for tougher spots.

Method 2: The Baking Soda Paste

Baking soda is a fantastic, mild abrasive. It doesn't chemically dissolve the oil, but it provides just enough grit to help scrub the oil particles loose from the asphalt's surface.
  • How to do it: Sprinkle a good amount of baking soda over the stain. Add just enough water to form a thick paste. Scrub vigorously with your stiff brush for several minutes. Let the paste sit on the stain for about 30 minutes to do its work, then rinse it all away with water. For a little extra power, some people have success using boiling water to mix the paste & rinse. The heat can help liquefy the oil, making it easier to lift.

Method 3: Powdered Laundry Detergent

Similar to dish soap, powdered laundry detergent has powerful surfactants. The powdered form also adds an abrasive quality, much like baking soda.
  • How to do it: Cover the stain with powdered laundry detergent. Add water to make a paste & scrub it in with your brush. Let this sit for at least 30 minutes to an hour before scrubbing again & rinsing with hot water. This is often a surprisingly effective method for stains that dish soap alone can't handle.

Method 4: The Coca-Cola Trick

This one sounds like an old wives' tale, but there’s some science to it. The phosphoric acid & carbonic acid in cola are what make it an effective, albeit mild, cleaner. It’s great for breaking down rust & can also help lift oil stains.
  • How to do it: First, wipe up any excess oil. Then, pour a couple of cans of room-temperature Coca-Cola directly onto the dry stain. Let it sit for a good long while—at least 6 hours, or even overnight is better. The acids need time to work. After it has soaked, you can scrub it with your brush & then rinse thoroughly with water. It's an economical option to try before moving on to harsher chemicals.

Method 5: WD-40 - Fighting Oil with Oil

It seems counterintuitive, but using a light, penetrating oil like WD-40 can actually help dissolve a heavier, set-in oil stain. Since WD-40 is a solvent, it can work to break down the grease.
  • How to do it: Spray a liberal amount of WD-40 over the entire stain. Let it soak in for about 30 minutes. Then, scrub with your stiff-bristled brush & rinse with water. You might want to follow up with an absorbent like baking soda or cat litter to soak up any remaining residue.

Leveling Up: Commercial Cleaners & Degreasers

If the DIY methods aren't cutting it, it’s time to bring in the big guns. Commercial degreasers are specifically formulated to tackle tough, petroleum-based stains. You can find them at any auto parts or home improvement store.
Some of the most commonly recommended products include:
  • Oil Eater Cleaner & Degreaser
  • Zep Industrial Purple Degreaser
  • Simple Green Pro HD
  • Purple Power Industrial Cleaner/Degreaser
These are heavy-duty cleaners, so it's REALLY important to read & follow the manufacturer's instructions carefully.
General Steps for Using a Commercial Degreaser:
  1. Safety First: These are powerful chemicals. Wear rubber gloves & safety glasses.
  2. Prep the Area: Sweep the driveway clean of any loose dirt or debris.
  3. Apply the Cleaner: Pour or spray the degreaser directly onto the oil stain. Many are concentrated, so check if you need to dilute it first.
  4. Let It Dwell: Allow the product to sit on the stain for the recommended time, usually 5 to 15 minutes. This gives it time to penetrate & emulsify the oil.
  5. Scrub: Use a stiff brush (a wire brush might be necessary for very old, stubborn stains) & scrub the area hard.
  6. Rinse Thoroughly: Use a strong stream of water from a hose or, even better, a pressure washer to rinse away the cleaner & the lifted oil.
  7. Repeat if Necessary: Deeply set stains might require two or three applications.
A newer type of product on the market uses microbial cleaners. These use microorganisms that literally "eat" the hydrocarbons in the oil stain. Products like Terminator-HSD fall into this category. You pour it on, add a light mist of water, & wait. It's a slow process that can take multiple applications, but it requires no scrubbing & is very eco-friendly.

The Poultice Method for Deep Stains

For the most stubborn, deeply embedded stains, you can try a method contractors sometimes use called a "poultice." A poultice combines a solvent with an absorbent material to draw the stain out from deep within the pavement.
  • How it Works: You saturate an absorbent material (like kitty litter or sawdust) with a strong solvent (like acetone). CAUTION: Solvents like acetone are highly flammable & their fumes are hazardous. This is an advanced method that requires extreme care, proper ventilation, & protective gear. You then apply this saturated paste to the stain, cover it with plastic sheeting to prevent the solvent from evaporating too quickly, & let it sit for several hours. The solvent dissolves the oil, & the absorbent material draws the dissolved oil up & out of the asphalt.
There are also pre-made poultice products available, like PROSOCO's Oil & Grease Stain Remover, which come in a paste form you just apply, let dry, & sweep away. This is a much safer option than mixing your own with volatile solvents.

When to Call in the Pros

There are times when even your best efforts won’t be enough. If you’ve tried multiple methods & the stain is still there, or if the oil has been sitting for years & has caused the asphalt to soften, it might be time to call a professional.
Professional pressure washing services have equipment that's far more powerful than what you can rent or buy. They often use hot water pressure washers or steam cleaners that can heat the water to liquefy the oil, making it much easier to remove. They also have access to professional-grade chemicals & the experience to know which ones to use without damaging your driveway.
The cost for professional driveway cleaning can range from $150 to $400 on average, depending on the size of your driveway & the severity of the staining. While it's an added expense, it can be worth it to get the job done right & avoid the frustration of a stubborn stain.

The Nuclear Option: Sealcoating

If a stain is simply too old or deep to be removed, or if the oil has caused permanent discoloration, your best bet might be to sealcoat the driveway. A fresh sealcoat will cover the stain completely & give your entire driveway a uniform, fresh black finish. It’s important to clean the oil stain as thoroughly as possible FIRST, however, because applying sealer over an oily spot can cause the new coat to peel & fail to adhere properly.

Prevention is the Best Medicine

Once your driveway is clean, you’ll want to keep it that way. The best way to fix an oil stain is to prevent it from happening in the first place.
  • Regular Car Maintenance: The most common cause of driveway stains is a leaky vehicle. Regular maintenance can catch small leaks before they become big problems.
  • Use a Drip Pan or Mat: If you know you have a slow leak, place a piece of cardboard, a drip pan, or a dedicated oil mat under your car when it’s parked.
  • Be Careful During DIY Work: If you’re changing your oil or doing other automotive work, lay down a tarp first. It's also a great idea to keep all your fluids & tools neatly organized. This is where a service like Prked can be a great storage solution. Instead of cluttering your garage, you could rent a nearby secure space, like someone's garage or shed, to store your car maintenance supplies, keeping your own driveway area clean & safe.

A Clean Driveway: An Opportunity to Earn

Speaking of driveways, once you have yours looking pristine, have you ever considered it could be more than just a place to park? A clean, well-maintained driveway is an asset. And with a platform like Prked, that asset can become a source of passive income.
If you live in an area where parking is tight—near a downtown, a university, a train station, or an event venue—your empty driveway is a valuable commodity. You can list your parking spot on Prked & rent it out to drivers who are looking for convenient & affordable parking. It’s a super simple way to monetize an underutilized space. You set the schedule & the price, & suddenly your clean driveway is making you money. It’s a pretty cool side hustle that requires almost zero effort once you're set up.

Final Thoughts

Dealing with an oil stain on your asphalt driveway is definitely a pain, but it's a battle you can win. Start with the simplest, gentlest methods like dish soap or baking soda & work your way up to stronger solutions if needed. Remember to always act as quickly as possible on fresh spills by soaking them up with an absorbent like kitty litter.
And if all else fails, don't be afraid to call in a professional or consider a fresh sealcoat to restore your home's curb appeal. A clean driveway not only looks great but also protects the longevity of your pavement.
