How to clean stained concrete?

[Mark B]

Hey guys,
I spilled some ATF on a concrete garage floor. Anyone know how to get the stain out? Are there any good products out there?

THere are hundreds of products out there. We had some oil stains that were like 15 years old, so we got Straight Acid and 2500 psi Washer. Im should with some Concrete cleaner, some scrubbing and water you should be ok.

could use a lil brake cleaner or gas on a rag then use some industrial strength floor cleaner(i forget what we use at my job)

I would like something that is waterless & wont be to obvious that I am doing it. The spill is in a storage unit that I am renting & I wasnt exactly susposed to be working on my car there to begin with. haha

For oil based stains, use some dry laundry detergent. It absorbs the oil and diminishes the stain. Then, use some acid based cleaner (citrus based works well) and pressure wash the residue. If that doesn't work, try the dry detergent again, and repeat. I used this method to clean my garage floor priot to epoxy sealing.
