Removing Oil stains on asphalt driveway

   / Removing Oil stains on asphalt driveway #11  
Goo Gone is a orange oil based product, that is basically the same as the non petroleum sprays used to keep asphalt from sticking to a dump truck bed, or to clean tools where diesel isn't allowed. It's not nearly as aggressive, but I would only try a very small area with it to make sure it doesn't make things worse

As Paul Harvey said transmission fluid is solvent for asphalt. What you are seeing is structural damage to asphalt. Try dawn to minimize damage by removing asa much of spill as possible. I would hand scrub and not use pressure washer

Issue is the oil attacks the Asphaltic Cement in the asphalt, ie the binder. You might try a weed burner to burn off the spill; but diesel, and hydralic fluid are he'll on asphalt. The picture is from a fuel spill, about 40-80 gallons on a roadway, and I could easily stick a screw driver through the asphalt, down to the base rock, with maybe 20 lbs of force. The whole affected area is gonna have to be milled out and repaved.

Yeah, no that’s not going to need to happen in my case. We are cleaning it up as best we can and not doing any milling or repaving, but thanks for the fear tactics.

I‘m not seeing any “structural damage” to the asphalt, but thanks for the laughs.
It’s a mild stain, but it’s about 100’ long and I need to clean it up best possible.

I am using kitty litter and hand scrubbing with Dawn and a scrub brush on a wooden pole.

I wasn't trying to say that in your case; but kinda just had the picture from work recently, and yep, that's really the only way to actually deal with petroleum damaged asphalt. Through the years, had many fuel spills (normally less than 120 gallons; although one was 6500 gallons of gas); hydralic, car fires, ect damage asphalt. A big depending factor, is how long it sits on asphalt, and how old the asphalt is (it appears old crappy asphalt with almost no AC content left, doesn't get attacked as bad), and of coarse the aggressiveness of the spill.

When I was much newer in construction, I ran over a 5 gal can of oil based Kilz paint on a brand new parking lot. Talk to painter; he says, odorless mineral spirits won't hurt anything, its about the mildest solvent know.... Every single time we broomed that area before we turned it over to owner, we never stopped brooming out aggregate.... think asphalt dollar general parking lot, ever notice the loose rock at the front 1/3 of the parking spots, oil leaks have broken down the asphalt.

Hay dude
The structural damage is that the transmission fluid is stripping the asphaltic cement from the aggregate. You can minimize damage by removing as much of the fluid as you can. I have been in asphalt industry for over twenty years

Had the misfortune of blowing a transmission oil return line down onto a customers driveway. Immediately Did the usual dose of kitty litter/absorbent.
This is no puddle. It’s a 100-150 foot long puddle.
Kitty litter did a decent job on what oil was laying on the surface, but now I still have the stain. I have been given a few different suggestions on remediation.

1. Wait until it dries and seal driveway. Issue with that is the driveway is 1000’ long. Might look odd to seal only 100-150’ of it. Whole driveway would be very expensive

2. Power-wash driveway with a Dawn & water mixture. Still pondering this solution.

Anyone else had luck with a very large stain like this?

Apply Tide, then rinse. Sooner the better. (Before someone asks, yes, the liquid, not the powder or the pods)

tell him sorry and it’s going to go away within a few years … he should understand it is not your fault, cleaning it for environmental damage i understand but you can’t loose your shirt fixing it and he has to understand that.

The premium NAPA floor-dri 8822,the white-ish stuff cleans very well.
Apply,crush in if possible,let it sit and not get wet.
Sweep up.

Have insurance or afraid to use it?

Best of luck to you!
