What to do with those grease stains on concrete. - Page 2

Be careful taking a flame to your concrete. Heat it up too fast and you will boil the moisture inside and cause the cream layer on top to explode.

Thanks for all the responses!

First they saturate the concrete with laquer thinner, then use a stiff bristle broom (or brush for a small area) to scrub the laquer thinner in. Then they use a weed burner to burn off the laquer thinner. Then they use a water hose to soak the concrete and spread Tide laundry detergent which is then scrubbed with a clean stiff bristle broom. Then it is rinsed off with water.

This is a lot of effort but it really does pull the grease out of the concrete. The drag strip crew said they have tried lots of other methods, but this is the only one that worked. Also, they suggest the guy spreading the laquer thinner not be the guy using the torch.

That sounds like a lot of work but I'm sure it works. I may have to give it a shot! Thanks!

Good idea. Thanks!

Dawn is pretty good on Grease

You might try pouring a can or two of coke over the area and leave it sit overnite and hose it down--the acid might remove the stain. If not coke then try baking soda and bleach with a scrub brush. I have used both methods with sucess.

No one suggested oil speedy dry? (I did see someone said kitty litter).

If you don't want to buy a bag, stop by your local auto garage and ask if you can have a coffee cans worth of speedy dry.

On fresh oil that's sitting on the surface you just need to cover it with oil dry and let it soak it up...then just sweep it away.

For old oil stains you'll want to let the oil dry sit on the concrete for a while...the longer the better. You can also "mash" the oil dry with your foot to break it up on the concrete. We used to do this in the farm shop...let it sit a day or two and then sweep it up.

Hit the stain with a couple of cans of brake wash. It'll really dilute the grease and make the stain a lot lighter, so much so that with regular weather, rain and such, the stain should just disappear. I do this when I get engine oil on our parking pad.

YEPPERS!

We used huge amounts of "Oil Zorb" in the machine shops.
Kitty Litter works almost as well.

Sometimes, you need to "grind it in" with foot traffic for a day or two.
But, It has cleaned up every grease stain I have ever seen on concrete.

Good Luck.

Go to auto zone get purple power pour it on let it sit and hit it with a power washer

Soybomb · 07-01-2011, 04:01 PM

A pressure washer works wonders.

Woodmonkey · 07-01-2011, 05:48 PM

I buy from Lowe's here in Florida a can of white goo that is called oil stain remover or something like that. Ask in the paint dept. Don't have any right now about $10 quart or so, Brush it on and let it dry. May have to do a second time but it is fantastic. Have used it for several years on the driveway which is paver bricks.

jgh1204 · 07-01-2011, 05:51 PM

DO NOT TRY YOUR WEED BURNER. Also, do not ask how I know.

If you don't have a pressure washer, take some naptha and scrub into the grease spot. Then cover with grit and grind the grit in with a broom. That was my job when I was 16 was cleaning oil spots in a parking garage.
