Best driveway degreaser/stain remover?

[frapjap]

I'm sure that at some point in time everyone here has spilled oil, coolant, ATF, diff fluid, something on their driveway.
I've recently spilled a bit of oil and coolant onto the black top asphalt driveway and can't seem to get it up worth a damn. I've tried Dawn, concentrated Dawn, and a couple of expensive degreasers from Lowes applied with a strong scrub brush but haven't even put a dent in the stain.
Can anyone recommend a good degreaser safe for a black top drive way?

you need to get an enzyme based cleaner, they work great and won't stain the driveway. As long as the cleaner (enzyme) is wet, it will eat the oil away, if it dries, the enzymes die as well.

I would check with where your company buys it's cleaners from and see if they have one and maybe they could send you a quart as a "sample"

Just make sure the enzyme is designed to eat grease, there's other types out there.

pressure washer?? I've always heard use kitty litter to absorb the oil/grease then use a detergent, whether it be laundry or dish. The enzyme cleaner mentioned above seems like a great way to go to.

Do you know what the appropiate enzyme is called? I'm reading about something called Trisodium phosphate.

Spray Nine has one called Bio-enzymatic cleaner.

I think your company uses Eco Lab, I'm positive that they would have something similar.

If all else fails, next time you're up here, I can give you some of the one that my company makes. We only sell it through remediation or restoration companies however.

Damn, I completely forgot what this chemical is called. Its like an orange powder that you sprinkle on to a wet driveway and then scrub in with a broom. It turns green. Then you pressure wash it and it cleans A LOT. I'll ask my dad what its called

Here is the kitty litter way from ehow.com http://www.ehow.com/how_12070598_clean- ... veway.html

Tri Sodium Phosphate is what you guys may be thinking of.

I have used bleach for small oil spots works pretty well but does make the concrete lighter then the surrounding areas. I hate it when people park in my spotless driveway knowing darn well their car leaks.

Purple power is pretty awesome.

Muriatic Acid

Moonshine, seriously, my dad used it to dissolve tar stains, oil.

Cascade dishwasher detergent might help.

Well I can tell you from experience that human blood doesn't work. No matter how much of the stuff I drip on my driveway, it never gets any cleaner.

IIRC, it's all a process. You gotta start with the kitty litter for a few hours, then sweep it up, then lay down a nice covering glob of degreaser and let it soak for a few mins, then use a brush to work it in and wash it away real good with a hose. Then comes the Muriatic.

This is, at least, how we handled stains left by the plumbers on pool surfaces after they were done. But I've never seen a way to do it that didn't make the concrete a little lighter than the surrounding area, however. (but that doesn't mean it's not out there)

Brake cleaner works very well. Its pricey for a big job, but for small spots its awesome.

[PapaSmurf2k3]

+1 for brake cleaner, especially on smooth concrete floors.

For that porous surface s***, I've always just kitty littered the crap out of it. Grind that s*** in with your shoe. If you need some sort of degreaser, sweep up the kitty littler, put down some fresh stuff and add degreaser to it (maybe a little water). THEN grind it with your shoe again. This more or less takes the place of the brush people were talking about earlier. Sweep it up or hose it off, then put down more kitty litter.
Note, when I say kitty litter, I mean that "oil-dry" stuff that is actually meant for it.
