Although there isn’t a space in a parking lot free of motor oil stains, that doesn’t mean you want your driveway to look like that. So if your car has leaked oil onto your concrete driveway, this article will give step-by-step tips on how to eliminate the stain.
All kitty litter really is is clay. And that clay is not only great at absorbing cat urine, but aces at absorbing improve gas mileage oil. So step one, get your regular run-of-the-mill kitty litter (don’t worry about those fancy “crystals”) and spread it onto the oil stain. Use a newspaper to cover it, and pat it in. Leave this overnight.
The next day, clean up the kitty litter. You’ll want to put this in its own plastic garbage bag so it can be disposed of properly, as this is oil and not meant for the regular garbage pick up.
Powdered Laundry Detergent
Now spread powdered laundry detergent over the stain in a thin layer. Next dampen the detergent so it has the consistency of paste. Then, just like with the kitty litter, cover it with newspaper and let it set overnight.
In place of the powdered laundry detergent, you can use a combination of Arm & Hammer baking soda and Oxyclean. If you have these at your disposal they are very effective in breaking down and soaking up the embedded oil in the porous concrete. If you use this alternative, you do not have to leave overnight as it is faster acting but you may want to make sure you give a good scrub to make up for the time that gravity would do the work of letting all the powder work its way into the concrete. Therefore, you don’t need to set overnight but can continue to the next step.
Lastly, clean up and remove all but a fine layer of the detergent paste. Add some water and grab yourself a tough, heavy wire brush. Now use some elbow grease and scrub the detergent into the concrete. Scrub in small circles, adding water if needed to maintain the paste consistency of the detergent. Make a point to scrub slightly outside of the stained area to give the unaffected concrete and the stained area a similar shade.
A discoloration may still be present. If it’s light, you can leave the area alone and the color should fade in time with sun exposure. If the stain is still prevalent, go back to the detergent step and clean again. This is similar to a scar on the human body and will slowly fade over time.
