Cement Oil Stain Removal
- Read and follow all labels on any detergents or chemicals you decide to use for oil stain removal. If at all possible avoid allowing any runoff from the cleaning materials to run into sewers or storm drains. Your local waste collection service can offer guidelines for your municipality.
- Put down clay cat litter, sawdust or dry concrete to absorb the bulk of the grease stain. You may also choose a commercial product designed specifically for removing oil stains from cement. Allow it to set undisturbed on the oil stain for a couple of days. Sweep up the oily absorbent material and dispose of it in a bag according to the directions given to you by the waste disposal service.
- Select a detergent that specifically identifies itself as a de-greaser for best results. Liquid dish washing detergent is a good option. Wet down the area surrounding the stain so that the stain doesn't spread as you try to clean it up.
Pick a nylon bristle brush with fairly stiff bristles. Don't use a wire brush because it can damage the surface of the cement.
Scrub the driveway with the detergent and brush. Mop up as much of the liquid mess as you can with absorbent paper towels. Dispose of the oily residue properly.
Allow the grease stain to dry. Repeat the scrubbing as necessary to remove the stain. If one detergent doesn't seem to get all the stain, try another product. Remember that an older cement stain is harder to remove, as is one that's on a rough surface. - Select a product such as muriatic acid or other similar chemical to take up tough grease stains. Realize that you must follow all directions carefully when using this type of product. Failure to do so can result in damage to the top layer of the concrete driveway or floor that can be worse than an oil stain.
