Oil spots on concrete can be unsightly. They gather dirt, become thick and slimy and the worst part... they just flat out look bad! Not to worry! A little elbow grease can go a long way.
Clean oil spots using a commercial de-greaser, a tough bristled broom or brush and hot water. You may have to brush and rinse a few times to get all of the oil off but in the end it's well worth the effort. Just be sure to rinse off all of the de-greaser when you're finished.
