How do you get an oil stain off of concrete?

Muratic acid........makes it like new.

Sandblaster

By the way, 99% of these people answering have NO CLUE what they're talking about...

Ok i worked at a body shop and this works great. we always had oil and transmission fluid spots until we did this. first you sweep the area and get up as much of the oil as possible. then you take some kitty litter and put it on the stain. then take a 2X4 block about a foot long. use the 2X4 to grind the kittylitter into the stain do this for about five minutes until the kittylitter is reduced to powder. then sweep up the dust and there should be no more stain. if not just repeat. this will work on smooth concrete or rough concrete.

There are a few companies that make concrete cleaners on the market. My personal favorite brand is Zep. Get a stiff brush, and hook up the hose, squirt some cleaner on the stain, scrub it with the brush, and rinse it away. You may have to do it a couple of times, if the oil has soaked into the concrete for a long period of time. Remember, the stain didn't happen overnight, so it may take a while, but it will work.

Good luck.

Most hardware stores will sell a specific cleaner for oil stains. Some are liquid and others are powders that you leave on (like the kitty litter some answerers have suggested). I used one of the liquid products when I had a stain inside my garage and it worked pretty well. You pour it one and spread it out, it then dried to a powder which you swept up.

If the stain is outside I usually don't bother. I live in a hot area and find that driveway stains will eventually bleach away due to the sun and rain. Most driveway stains (where I live) only last a couple of months.

Kitty litter will soak some of it up, so spread some of that over the stain. After a couple of days, sweep up the kitty litter and apply a degreaser, the kind sold at Napa Auto Parts or any another car parts store. As someone who works there for advice as to which product works best, and then follow the directions on the bottle. If all that fails to work, try a power washer.

To get an oil stain off of concrete is pretty easy. All you need is some D40, a plastic bristle brush ,and some water. Apply the WD40 let it set for about 1 minute, then scrub the oil stain,add a little more WD40, then rinse!!

Soak it with pine sole then use fresh kitty litter use your feet to grind the litter into the stain sweep up the litter keep repeating this until the stain is gone this will take a while because the oil soaks into the concrete they make a sealer for concrete that will keep oil from soaking into it good luck.

First get some washign substance such as greased lightning. Spray that on it (I perfer it because it gets rid of everything) and scrub with a little bit with water. (BAsically make a puddle of it with oil on top since it was scrubbed) then blow it into the street / grass/ wherever. (Power wash it for a greater effect.) I find that useing my 4000 PSI washer really does the trick. (It takes off a layer of concreate literally) After that get some cat litter and make a puddle of water and poor the cat litter all over it. LEave it there for a few hours. If this all fails then use Oil Eater. It works great and thats what it is meant to do. Below is a link to some oil eater. That should do it.

WOW, so many good answers.

After the kitty litter and the cornstarch,

what I'd do is;

1. Pour vinegar and baking soda over the stain, and brush-scrub it.

2 Pour bleach on the stain, and then do the same scrubbrushing thing.

3. If all else fails, PAINT the entire driveway in your favorite color..

Not against any zoning regs I've ever heard of, and it will impress the neighbors a whole bunch.

Or get someone to tar the entire driveway. :=}

I'd first try using straight bleach out of the bottle, pouring it on the stained area and letting it set for about 7-10 minutes. Then, using a very sturdy wire bristle pushboorm, scrub the area--c'mon now: put your back into it.

If the stain's really really tough, you may have to repeat this a couple of times till it fades. Once the stain fades, I'd go to pouring straight bleach on the area.....and use a very high pressure water jet hose on the stain.

There are store shelf "oil remover" solutions sold, but I've been told to really be wary of their claims.

If you grind kitty litter into the oil stain, and sweep it up after you're done. That's always worked for me and I've had to clean up oil stains on concrete under Tanks!
