Maybe you parked your car in the driveway and found out that you had a small leak; Maybe you park in an apartment complex and the property management company is mad because your car is leaving stains in the driveway; Maybe you decided to change your oil yourself for the first time, and accidentally overshot your catch pan. Whatever the reason for the stain, there is a quick and easy way to help clean up your driveway.
Cars have multiple types of fluids and many of them are oil-based or "greasy". This could seem near impossible to clean out of a porous concrete driveway. Watch this quick video below for an inexpensive way to lift stains out of concrete. If it doesn't get the whole stain the first time, you can always repeat for better results.
Please feel free to let me know if this worked for you, or if you found a technique that works better!
