Oil stains can commonly build up on brick driveways, as cars pass through leaving behind road debris, a small leak causes oil to drip, or simple do-it-yourself maintenance that leaves an oil stain under the engine. In any instance, luckily it is fairly simple to remove these oil stains when using the right cleaning elements. There are a variety of retail products available, but a simple home-made solution will work just as well while saving you money.
For fresh stains, a simple cat litter application will handle the problem. Keep an inexpensive bag of cat litter on hand, and when an oil stain occurs, cover the stain with a thick layer of cat litter. Let sit for a day or so, and the cat litter will work to draw out the stain. Sweep up the cat litter, and the stain should be greatly diminished, or in most cases removed completely.
Liquid dish detergent has a degreasing agent that will effectively remove oil stains without harming the brick driveway. When a stain occurs, grab your normal liquid dish detergent, and squirt directly onto the stain. Then, use a stiff brush to scrub the stain, adding a little water when necessary. When the stain has been removed completely, wipe the area clean with a damp cloth to remove any remaining dish soap or oil residue.
Cornstarch also works as an absorbing agent that will draw oil stains out of brick, and this is a completely mild, harmless ingredient to use. When a stain occurs, sprinkle a thick layer of cornstarch over the stain, and let stand for 30 minutes. Then, add a few drops of water, and scrub with a stiff brush. Repeat the process as needed until the stain has been removed. For tough stains, add a cup of cornstarch to a dish, and stir in water until a thick paste has formed. Then, apply a thick even layer of this paste to the oil stain. Let sit until dry. This could take anywhere from a few hours to overnight. Then wipe clean with a damp cloth.
