There are other safer products you can use. I believe the products listed in Mathias's response are highly flammable. The stain is not that bad. You also want to wear eye protection, have good ventilation and toss out any rags and materials used to wipe up. Rags should be put outside on the grass spread out to allow the cleaner to evaporate. If left in a pile there is a danger of fire due to spontaneous combustion.
I have special gloves used by the military that reach up to the elbow and prevent chemical burns. Grainger may hav special gloves for spill cleanup or material applicatio

McLube technical reps recommend toluene or MEK for cleaning. Both are pretty nasty stuff and I'm not sure how well it will get it out of concrete. I know toluene works well on B-72 as well. I would definitely wear gloves and a respirator mask with either. Acetone and MEK both break through nitrile very quickly, butyl is better. Toluene breaks through just about everything, but nitrile is best.
It may be worth reaching out to McLube to see what they recommend.

Hello,
I have a few stains in concrete (all in the same spot) from McLube 1725L/TFL-50 Dry sprays and Paraloid B-72 spills. I tried to let acetone set on the B-72 spills and scrub with a brush/soak up with a towel which I believe got rid of the B-72 but I think the white Teflon from the TFL-50 Dry is still showing.
Any way to get this stuff out?
Thanks
