How do I get oil stains out of my concrete driveway?

Answer 1

Whether or not they come out depends on how deep they are, and how long the've been there. Fresh surface stains can be washed away with a high pressure (1000 - 2000 psi) water spray and detergent.

Try muriatic acid on tougher stains, available any place where pool supplies are sold. It is fairly cheap and widely available. Pour it on and scrub with a push broom. After scrubbing, neutralize it with some baking soda and hose off.

The acid reacts with the mortar in the concrete. Several light applications/scrubbings are better than one long one because you are replinishing with fresh acid.

Good luck.

Answer 2

Stop by your local hardware store and get a bottle of greased lighting.Pour it on the stains and it will lift the oil out of the concrete.Later hose off with the garden hose.Greased lighting will not kill grass or plants next to the driveway.

Answer 3

Use a driveway cleaner, most all home department stores, lowes, home depot and such have them. Use a pressure washer to really get the stains out. If that doesn't work, paint it with a driveway paint. You can paint it natural gray concrete color or what ever you want.

pour and restore stain remover, this stuff rocks!

I use "oil eater" cement cleaner I get at costco first to get most of it off, then the more expensive pour and restore after to get it 98% clean.

Answer 5

Visit your local auto parts store and ask. If your driveway is asphalt (black tar), forget about it. Tar is made from oil.

Answer 6

for about the sixth time; Use a commercially available product called "Speedy Dry"; it's available at most larger auto parts retailers or hardware stores. If that doesn't work, try muriatic acid which is available at hardware stores, but be very careful using that because it eats holes in clothing, skin and will damage lawns, plants and kill other lioving things.

Answer 7

Use fairy liquid to remove the grease and a pressure washer.
