How to Remove Oil and Grease From Concrete

Do you hate those nasty stains on your driveway or garage floor? A leaking car or lawnmower can do quite some damage to a garage floor. Here's a nontoxic home remedy for cleaning them up.

Difficulty: Easy

Instructions

Things You'll Need:

• Ready-to-mix Cements
• Sawdust
• Kitty Litters

1. 

   Spread a thick layer of fresh sawdust or kitty litter over the grease to absorb excess grease or oil on the surface.

2. Allow the sawdust or kitty litter to sit for a day or two.

3. 

   Gently sweep away the dirty sawdust or kitty litter.

4. 

   Pour dry cement over the entire dried grease spot.

5. Allow the cement to sit for a day or two.

6. 

   Gently sweep away the dirty cement.

7. Gather dirty cement in a bag and throw it away. Do not allow the dirty dry cement to go down the sewer.

Tips & Warnings

• The kitty litter and sawdust soak up grease on the surface, whereas the dry cement actually absorbs the stain out of the driveway.
• For best results, clean up grease stains as soon as they happen.
• Avoid further staining by using large automotive drip pans for vehicles that leak.
• Make sure the forecast is clear for the days you'll be using dry cement on the grease spots if they are outdoors. Dry cement and water will create hardened concrete.

on 6/10/2009 I found a new product which removes oil stains and fuel spills from any surface without using toxic chemicals. It�s called Oil Gone Easy S-200 and can be used on asphalt, concrete, brick and soil. Instead of using noxious cleaners or solvents, you just pour Oil Gone Easy S-200 on the stain and it attracts locally existing microorganisms to literally eat the oil until it is eliminated within a week or two. It�s very easy to use, involves no mess and best of all there is no clean up required. This technique is totally green and much cheaper than conventional cleaners. The product was used to clean up the Prestige oil spill off the coast of Spain and is recognized by the EPA. Oil Gone Easy is referenced in Wikipedia.

on 4/13/2007 By far the best thing I have found to remove persistent oil and gasoline or diesel spills from concrete or pavement is BIOSOLVE. You mix it with water and apply through a garden sprayer, hit it with a hard bristle brush (a roofing brush works great) and the surface isleft clean and free of residual slickness. I have also utilized it through a pressure washer with great success! Once gallon more than enough for small spills (product is concentrated) Also, it is environmentally friendly and easy to work with.

on 2/27/2007 Remove Oil from concrete - If Kitty Litter doesn't get out all of the stain, I've found a product that got rid of even old stains from my driveway and garage. "Eximo concrete cleaner" claims to be an organic process, and it was really easy to use.

on 11/22/2005 If you have oil stains on your driveway or garage floor, fill a bucket with sawdust and mix it with a liter of White Spirit. Cover the oil stain with the mix, then cover the sawdust with a garbage bag. Weigh down the edges with sand, let it all sit a day or two, the sweep up the dust. Any remaining oil can be scrubbed clean with White Spirit. No smoking on this job!!

on 11/22/2005 "Go-gone" works great! It's better than "Simple Green" or Zep's products. Use a scrub brush.
