What chemical or method is best for removing diesel fuel or oil stains from concrete, as in the driveway? I had a 4th of July party and someone's diesel drooled (sp?) fuel and oil on my pavement! Thanks!
You'll be amazed just how well oil dry works. I don't think it's that expensive. I keep it around to clean up oil spills. We use it to clean up red dye spills and concrete. Some of it has been sitting awhile. If it doesn't work, try some degreaser or a power washer.
