How to remove oil from driveway
Try covering with a thick layer of cat litter...let sit for a few hours then remove by sweeping or blowing. Litter is made to absorb urine so it should work. (Buy a small amount to test first so you don't waste a lot of money if it doesn't do a good job!)
Clay cat litter is best for this. If stain is still there pour coke on it and let it sit for a few hours ,then rinse.
To remove dried oil from concrete, douse the stain with spray lubricant and then rinse with water, says Reader's Digest. Another method, according to the Los Angeles Times, is to put engine degreaser on the stain and scrub it with a wire brush, then cover with kitty litter before sweeping it up.
We have a newer concrete driveway that sometimes gets abused by contractors or service personnel. We try to observe and remove these oil stains ASAP. We use TSP for large areas or areas not treated immediately or this Easy off spray for stains we catch right away. Scrub with a stiff plastic kitchen type brush and rinse with water. Remember to wear personal protection as labels might direct.
