Getting Isocynate out of concrete
Anyone have any luck getting leaked iso out of concrete. Its not a driveway but it is outside of a commercial building. We have tried regular concrete wash, pressure washing, diluted muratic acid. Anyone have any luck with any other product or method that can draw the stain out of the concrete?

Tri Sodium Phosphate (TSP) might work, wet enough to be a paste and let sit.
Rinse and repeat.

an abrasive blast might clean it up...
