I'm looking for something that cleans oil off concrete?

Answer 1

Probably many things, but some stain is likely to remain.

I've used commercial degreasers such as found at a garage; caustic detergents; Hydrogen Peroxide; Muriatic Acid; etc.

Followed by pressure washing.

BTW: Bleach won't work, especially alone, and Kitty Litter is only to absorb surface residue and drips, it will not PULL oil out of concrete.

Answer 2

Depending on how oil the stain is will determine how to remove it. First, use "kitty litter" , yep, kitty litter, to cover the stain completely. This will absorb any oil that is still damp enough to be picked up so later it can be cleaned. TSP I hear works well, but call a "decorative concrete" in the phone book and ask for suggestions. They do make concrete stains, just like for wood, you could possibly stain it darker to hide the stain.

Answer 3

i have removed oil off concrete with a mix of cat litter and salt . you mix the cat litter and salt and pour it on the oil the salt will break up he oil and the cat litter will soke it up so that you can remove it easier or you can use sand for small amounts it works in my shop . If the oil has dried put some gas or carasen on it 10 min before you use the mix. don't leave the salt all the time it will eat the concrete after a wile...

Answer 4

Soak up excess oil with Kitty Litter, or a commercial absorbent. Then remove remaining stain with Tri Sodium Phosphate. Note on TSP. DON'T get that stuff on your hands. Although it is quite safe, TSP can cause almost painful drying of the skin. TSP was litterally invented as a concrete cleaner.

Answer 5

Rochester Midland makes a bacteria that eats oil and turns it in to water. I haven't used it but I have used a similar product they make for organic stains and it is great. It's kind of pricey but would be well worth it for a large job. It's called Dfe Biozyme Degreaser. Check with your local janitorial supply store. Here's a link to one seller I found on the web.

Answer 6

Want to try something unusual?
Try WD40 which many people think is an oil. Actually it cuts oil.
Try a patch test and see.

Good luck

Answer 7

TSP - trisodium sulphate. usually found in the paint section. there it is used as a prep for painting (because it will clean cooking vapors that adhere to walls & ceilings). simply follow package instructions for your use. if not sure if it is safe to use on concrete, simply call the manufacturer.

Answer 8

i bf found this product at costco (Oil Eater). it not only took the oil off the concrete but i use it as a de-greaser for my oven.

Answer 9

Use a little bit of dishsoap and a pressure washer or a regular hose and a heavy duty bristle brush/broom, it will take elbow grease but, should works...

Answer 10

Good ole' clay cat litter! Apply and walk away leave it for several hours. It will absorb into the cat litter and just sweep it up.
