Removing old oil stains from driveway

[lt1fire]

Pressure washed the driveway today and removed a ton of dirt and oild but some of the stains are just not budging.

I've had mild success in the past with simple green bit want to know tricks others have used in the past.

muratic acid and a brush...oh and gloves. I have also heard of some using dawn.

One thing I can guarantee does not work is the concrete cleaner that you can buy for the pressure washer. But I got some here you can have.

This crap.

It's funny that Muriatic Acid is still called that, as Hydrochloric Acid is the more common name. Just don't mix it with bleach (if you think the 2 would be a better combo!) as it will violently release chlorine gas and kill your lungs or you...

Where can you buy this stuff?

AFAIK you can still get it at Lowws and the likes.

You can find it labeled as marine bilge cleaner in boating stores.
