What are you guys using to clean any soot-laden oil stains from a Third Gen off of concrete? Thanks for your help.

Bio diesel. B20 or higher works very well.
Does the job for oil stains from any Gen CTD!
Pressure washer is probably the best way to go...if a driveway and not a sealed surface.

I would get some degreasing oven cleaner and let it soak into the stain and scrub and then rinse. This works for me for new stains.

You can also use a watered down muriatic acid. I think that is the right one. I would check local regulations like if you are in a watershed area or something.

I had some drip onto the driveway, so i tossed kitty littler down in the area just incase any more was to spill. The kittle littler actually soaked up the little bit that got on the concrete... or it just soaked in to the concrete.... either way, there's no stain....

I bought painters plastic and lay that down along with kitty littler to soak up any spills... it's kind of a pain in the rear but much more easier then having to listen to the boss nagging that the driveway has stains on it....again

i use purple power or power clean for most oil grease stains around the house, truck, including work cloths

I poor a little gas on it and scrub it a little and light it.... lifts its right out

Thanks for the suggestions. So far nothing is working on the black stains. I found a source for B100 in Houston, may give that a try. I have a feeling I will be trying all of these methods!!!!!! Thanks again.
