Your house is in beautiful condition, your yard is looking wonderful with lush green grass and canopy trees letting the sun gently filter through. But wait, what is that ugly black spot in the middle of your driveway pulling the focus of your beautiful home. Oil on the driveway can be a real eyesore and a royal pain in the you know what. So how do you remove it? Well there are many degreasers available that do a decent job and if the stain is not too bad you could even try a mild detergents and scrub brush. For the stubborn stains that have penetrated deeply over time you may want to try a poultice, which is basically a soft moist mass in the form of flower, baking soda or even powdered sugar mixed with acetone.
Mix the two together to get a paste texture, then spread it out over the stain about the thickness of an Oreo cookie. Cover it with plastic such as Saran Wrap and tape the edges down to make it as air tight as possible. What happens next is the poultice acts as a vacuum and draws the oil out of the concrete. Leave it covered for at least twenty four hours. You may need to repeat this a few times. Be sure that there are no sealers as they may be vulnerable to acetone.
