What is the best way to get oil stains out of a cement driveway? I think
they are mostly power steering fluid if that matters. I've finally gotten
rid of the car that leaked it, so if I can clean up the stains, it should
stay cleaned up. Any tips?
I just did this on my own driveway to clean up a persistent oil leak on
my car that I finally fixed. I tried all of the standard water based
(environmentally green) degreasers with little success. Muriatic acid
is dilute hydrochoric acid and will etch the concrete, but will not
dissolve or digest the oil. What you need to do is go to an auto parts
store or your local K-mart, Walmart, or Target and get a can of the
petrolium based engine degreaser. I had great success using the Gunk:
Engine Brite degreaser. Dont buy the foaming one it didnt work well.
The original gunk is a reddish petrolium base product that if you spray
on evaporates very slowly. Let it sit 15 - 20 minutes and scrub with a
steel brush if you have one and then rish with water. This worked
fabulously on my driveway will several year old oil stains. After the
oil stain removal I used an old broom to brush on a 50/50 solution of
water/bleach and let dry to brighten the cement.
A friend bought 20 pounds of kitty litter and poured it on the stain. Then
he walked on it with shoes that had no tread.. ( that is very important )
It took a lot of applications but the oil came out and it really did not
cost all that much.

I have also had good luck just piling on a 1/2 inch of some clay-based
granular cat litter, or a clay litter specifically sold for soaking up
grease. Then I grind the granules to a powder with an iron weight or my
heel. Leave the stuff on the stains for a week or more, and mash it with
your heel every time you happen to be out there. Acid may leave an etched
mark of its own, and the oil saturation may prevent the acid from etching
just where you want it to. I would try solvents at then end, to get the
hard-to-get residual, once the "wet" part is absorbed by the litter.
Subsequent (fresh) oil stains are really easy to get off if the litter is
applied right away.

What good is accomplished by pouring a quart of gasoline
on the stain and then doing nothing further until the gasoline
has all evaporated? All that you have accomplished is creating
a fire/explosion risk. Obviously you've never really tried this
method and had any success. If you were to blot up the gas &
oil mix, then you'd have some success. But there are much
Likewise, the advice with the hot water and detergent doesn't
seem very helpful. After pouring this on and scrubbing with a
broom, "your stains will be gone." Where did they go? You
must either (1) blot up the oil stain and/or (2) rinse it away.
Blotting is almost always the best approach. Rinsing will often
just spread a small concentrated oil stain and create a huge,
less concentrated oil stain. Just scrubbing with hot water &
detergent will never remove the oil stain. Where would it go?
You seem to be making up worthless advice which you've never
I just used 20% muriatic (hydrochloric) acid on mine. Took me only a few
minutes (for a single oil stained area). It worked great!
[Just be sure to use common sense safety precautions. Have your water spray
hose nearby and ready to use. Before you finish (or before leaving the
scene unattended for any reason), gently spray water over --so as to dilute
first, and then rinse harmlessly into the ground or storm drainage- any and
all of the acid.]
A power washer will make whatever detergent you use much more effective.
They have products specifically for that type of cleaning. See your local
Muriatic acid, if it does work will leave a bleached/etched spot as
noticeable as the original stain, you would need to etch the whole driveway
(if you do, it will be nicely ready for a transparent stain or sealer). It
would work by etching away the concrete holding on to the oil. deeper
stains may still not come out.
dish soap and scrubbing work for smaller stains
Gasoline makes a good solvent for oil but is environmentally unfriendly.
Denatured alcohol might be worth a try.
Geez, I spilled gear oil out (a quart or two) on my driveway when I had
to change a senson on an Infiniti (5 speed stick)
Anywho, to get the stain out I just used carb cleaner (gum out or
is on sale) That did the trick. Just make sure to clean the area of
first, then start with the carb cleaner. Spray it, wipe it down and
let it dry.
Worked for me.
Spread kitty litter, the cheap clay kind, over the stains and grind
into the surface with old boots. Sweep up the following day then
scrub with Dawn dishwashing detergent and water, rinse. You will
still have some stain, but it will be less noticeable and then less

Pour on just enough paint thinner to cover the stain. Let it soak for
a couple of minutes and pour oil absorbant clay over it (looks like
kitty litter but you buy it at autoparts stores). Grind it around with
your shoe until all the paint thinner is absorbed. Sweep.
That completely removes every kind of oil stain I've ever had to deal
