Oil stains on driveway

[Guest 1FASTC4]

Sooo the best way to really get them out effectively is?

I use a grease remover (Spray Nine right now - from Canada or OilEater from Costco) and then place cat liter on it to absorb remainder and scuff/grind it in with your shoes.

Here's a couple of quick internet solutions...

Oil and grease: Removal of oil from parking lots, drive-throughs, and other concrete pavements is the most common concrete power-washing application. In addition to hot water, an alkaline degreaser will greatly increase removal rates of oil and grease. Hot water lifts the oil from the concrete, and the degreaser emulsifies the oil, allowing it to be flushed from the surface. Some contractors use at least a little degreaser for most jobs, even to remove dirt, which can be somewhat oily. According to Hinckley, alkaline cleaners are also the preferred chemical for cleaning soot from concrete.

Oil can be very difficult to remove on most stone.Oils will penetrate deep into the stone and will spread out throughout the stone.Try to clean up the oil spill as soon as it happens.

Solution:

1.Blot up any excess oil with a clean white cloth.If oil has dried on the surface scrap with a sharp razor.

2.If oil is still fresh and has penetrated into the stone sprinkle a generous portion of dry poultice powder on the spill and let stand for 12-24 hours.

3. Remove the dry poultice and prepare a solution of commercial degreaser and water.Apply this solution to the spill and keep it wet for 30 minutes.Vacuum the solution up and blot the remainder with a clean white cloth.

4.If stain is still present poultice with a solvent(Methylene chloride works best) and a poultice powder like diatomous earth.
