Concrete is a versatile and durable material used for driveways, garages, basements, and more. However, oil stains can be unsightly and difficult to remove from concrete surfaces. Choosing the right oil remover is key to getting your concrete looking like new again. In this article, we will discuss the leading options for concrete oil removers, and provide tips on how to use them effectively. Read on to learn what is the best oil remover for concrete.
What Causes Oil Stains on Concrete?
Oil stains on concrete are usually caused by motor oil, cooking oils, grease, or fuel spills. Oil penetrates the porous surface of concrete, leaving behind hard-to-remove stains. Over time, the oil oxidizes and turns into a gummy dark substance on the concrete. Frequent parking of vehicles in the same spot can also lead to oil drips building up on concrete and asphalt. Fresh oil stains can appear as a dark spot, while old stains often have a yellow or brown tint. Identifying the source of the oil stain will help determine the best removal strategy.
How to Remove Oil Stains from Concrete
Removing oil stains from concrete requires using a powerful oil remover designed for concrete. However, the process also depends on how long the stain has set:
New stains: Addressing fresh oil spills right away is crucial. Immediately blot up any excess oil with rags or paper towels. Then, spray a concrete oil remover directly on the stain to break up the oil. Allow it to sit for 5-10 minutes before scrubbing and rinsing. This should lift most of the new stain.
Old stains: For dried, set-in stains, pre-treating is necessary for the oil remover to work effectively. First, scrub the area with a concrete degreaser or strong detergent. Then apply an oil stain remover, allow it to penetrate for 10-20 minutes, scrub vigorously, and rinse thoroughly. Repeat as needed for tough stains. Using a pressure washer can also help blast away the oil residue.
Proper protective gear like gloves, eye protection, and knee pads should be worn during the removal process. Promptly clean up any used materials. Let the concrete dry fully before re-staining or sealing.

Homemade Oil Removers for Concrete
For a more natural approach, you can make your own concrete oil stain remover using common household ingredients:
– Baking Soda Paste: Mix baking soda with just enough water to form a spreadable paste. Apply to the stain and let sit for 15-20 minutes before scrubbing and rinsing. The mild abrasiveness lifts oil out of concrete pores.
– Vinegar Solution: Combine equal parts white vinegar and warm water. Spray or pour over the oil stain. Let sit for 10 minutes, then scrub with a stiff brush. The acetic acid in vinegar breaks down oil bonds.
– Dish Soap: Make a concentrated soap solution by mixing 1-2 tablespoons of dish soap per 1 gallon of hot water. Scrub into the stain using a stiff bristle brush. Rinse thoroughly. Detergents emulsify grease and lift oil.
– Kitty Litter: Spread a thick layer of fresh, unused kitty litter over the stain. Let it sit overnight, then sweep away the litter. The absorptive properties draw oil out of concrete.
While not as immediately effective as commercial removers, these homemade solutions provide a more affordable and eco-friendly way to tackle oil stains with some diligent scrubbing. Test them in an inconspicuous spot first.
Tips for Using a Concrete Oil Remover
To get the best results from any concrete oil stain remover, follow these useful tips:
– Identify the oil type and age of stain – this determines the removal method needed.
– Pre-treat old stains with a degreaser to break down buildup before oil remover application.
– Apply remover liberally over stain according to product directions. Don’t let it dry on the surface.
– Let remover sit for recommended time to allow it to penetrate and lift the oil.
– Use a stiff nylon brush, broom, or pressure washer to agitate and loosen the stain as you rinse.
– Wipe up excess moisture to prevent oil redepositing. Allow concrete to dry fully before sealing or coating.
– Wear proper PPE – gloves, goggles, knee pads, and ventilated masks when needed.
– Properly dispose of used rags, towels, and remover according to manufacturer guidelines.
– Repeat treatments for stubborn stains. New concrete may require several applications.
With the right oil remover and some scrubbing elbow grease, you can successfully banish ugly oil stains from concrete. Pay attention to application instructions and safety precautions when using either commercial or homemade removers. Your freshly cleaned concrete will be revitalized and ready for stains-free use once again.
