We understand that oil stains on concrete are unappealing to the eye, but it is so much more than that! These stains also have a negative effect on the results of any coating you paint onto the surface, such as concrete sealer or epoxy paint. This means that it is essential to thoroughly clean the concrete, to ensure you remove oil from concrete before working on it. This may seem daunting, but (trust us) there are many ways you can remove grease from concrete. This article will not only show you how to get oil out of concrete but will also highlight the products that are best suited to getting the job done.



Oil Stains and Concrete

Concrete is a composite material that is made using water, cement, and either sand or gravel. When it is dry, concrete is hard but still porous, although the level of porousness depends on the size of the sand and gravel particles. Essentially, the porosity of concrete allows for water and vapor to move through it. While this is all well and good, it does mean that other substances can have the tendency to permeate through and stain your concrete.

Concrete Porosity is Stain Prone

Due to its porosity, it can be difficult to remove grease from concrete, as the oil can seep right into it. What makes removing oil stains from concrete even more tricky is the fact that oil is a natural water repellent. We strongly suggest, therefore, that you apply a concrete sealer to your surfaces, to make it easier down the line to remove any grease and oil build-up and stains.

Seal Concrete to Prevent Oil Stains

You may have noticed that your driveway and garage are where the worst concrete stains usually occur. This is a direct result of fluids and oils that sometimes (often without us even noticing because it is so slow) leak from vehicles. If this is the case, the stain on the concrete (however unsightly) should be the last thing you worry about and we strongly recommend you jump on a call as soon as possible to your motor mechanic to get that issue fixed. For now, let us discuss the more common stains found on concrete.

Oil Drip on Concrete



Gasoline spills (often occurring when the lawnmower or weed wacker are refueled) are a common mishap in the garage or driveway. It is important to clean these spills up pretty quickly, as gasoline is not only flammable but can also be toxic to animal and plant life.

Motor Oil

If you notice an oil stain underneath your car, it is almost always indicative of a larger mechanical problem. Another good thing to know is that the longer you leave the problem, the harder it is to remove the stain. During the course of this article, we identify several impressive degreasers that effectively remove grease from concrete.

Transmission Fluid

Another common stain that is often found on the garage floor is transmission fluid. Transmission fluid shows up as a red stain on concrete floors that are light in color. As with motor oil, the longer the stain is left on the concrete, the harder the stain is to remove.

Best Products for Removing Oil From Concrete

Learning how to remove oil from concrete can be as easy as using the right products. Oil is not water-soluble, so that will rule out using water to wash it off. You will need something a little stronger. Degreasers are the best way to go about this.

How to Get Oil Stains Out of Concrete

A commercial grease-remover is not your only option when it comes to removing oil stains from concrete. In fact, if you are wondering how to remove oil stains from driveways, there are a few other methods that work almost as well (and in some cases, they work even better) than a degreaser. If you have a stubborn stain, we suggest working through some of the other methods listed in this article. Go on… Give it everything you’ve got! We believe in you! But we also believe in being responsible, so if you opt for using chemicals, we strongly advise wearing safety goggles and gloves.

Oil Spill on Concrete


Soak Up the Excess Oil

If the oil spill is recent (very recent) and it hasn’t had a chance to soak into the porous surface of the concrete, then it is time to act quickly. If you let the oil sit on the concrete, it will seep into it, causing an oil stain. The longer you leave it, the harder the stain will be to remove down the line.

Immediately Remove Oil Stains from Concrete

If you act immediately upon noticing an oil stain, you can save both money and time by using everyday items you may already have in the house or tool shed to remove it.

You can use either sawdust or a cost-effective kitty litter to remove oil from concrete before it becomes a stain. Simply sprinkle it over the oil and allow it to sit for approximately 24 hours. Both sawdust and kitty litter are incredibly absorbent and will actually soak up the oil, thereby preventing it from leaving any permanent marks or stains. When either of these absorbent materials has done the work they need to do, simply shovel it up and dispose of it safely.

Cat Litter Gets Oil Off Concrete

The absorbent material soaking method works even better if your concrete floor has been sealed, but if you do notice some marks are left behind, you may want to consider trying one of the other methods mentioned in the article.


Poultice for Oil Stains

If a simple sawdust solution did not get the job done, then mixing up a special poultice is likely your next step to removing the oil stain. You will still need sawdust, wheat flour, or kitty litter (to act as the drawing agent), which you will need to mix with either thinners or acetone. This compound is more effective because each ingredient in the compound actively works to remove the stain. The solvent works to break down the oil, and the absorbent material or drawing medium is what pulls the oil stain from the concrete surface.

Thinners Remove Oil from Concrete

Mix the ingredients chosen to create the poultice. Then you can spread the mixture over the stain (don’t be shy) and place a piece of plastic sheeting over it. Let the compound get to work and leave it for 24 hours to ensure the oil has been both broken down and soaked up. Using a shovel, remove the poultice and be sure to dispose of it safely. This method is ideal for smaller stains, but that doesn’t mean it’s not worth a shot on your larger stained areas.

Waiting Time to Get Oil Off Concrete

With the poultice now responsibly disposed of, it’s time to give the surface a quick rinse with water and a mop. When the surface is dry, you’ll be able to see how effective this method has been on that pesky oil stain.

Mopping Up Degreaser on Concrete


Commercial Concrete Degreaser

A commercial concrete degreaser is most likely the first thing you thought to use when wondering about how to get oil out of concrete. We are honestly not surprised because this method truly works. Yes, you will need to give the area a good scrub in order to start the degreasing process, but if you’re working with a quality product (Goof Off concrete degreaser really is our favorite), it is hard to go wrong.

With any commercial degreasing product, it is best to allow the product to sit for 30 minutes before breaking out the broom (or any brush with stiff bristles). Once you’ve finished scrubbing, you’ll also need to rinse off the area well with water, because degreasers are often a high alkaline composition. As with any product, the manual is your friend. Not all degreasers have the same directions for use.

Scrub to Remove Oil from Concrete

Baking soda is yet another alternative solution if you’re thinking about how to remove oil stains from concrete. Liberally sprinkle the baking soda onto the grease or oil stain and let it sit for at least 30 minutes. Once enough time has passed, pour a good amount of dish soap onto the baking soda and start scrubbing. Once your arms are burning and you are quite sure you have gotten enough exercise for the day, rinse off the solution with warm water. Repeat if required.

Baking Soda Gets Oil Off Concrete

When mixed together, baking soda and detergent can be an incredibly efficient way to remove grease from concrete.


Removing Oil Stains From Concrete with WD-40

WD-40 is one of those over-achieving products that has about 2000 uses. Yes, you read that correctly. You could simply go into Target and there it will be, readily available. So it is a versatile and seriously convenient product. Speaking of versatility, it can be used to do a number of things, like…you guessed it – it can even be used to remove oil stains from clothing, because it contains ingredients that break down the oil, much like any degreasing product.



After soaking up as much of the oil as possible, generously spray the WD-40 directly onto the oil stain and let it work for at least 30 minutes. This is another product that may require some scrubbing, but the results will be worth it.
