How do you get black soot off burnt concrete? This is a area about 50X50 its the underside of a parking garage ramp. The concrete ceiling got high heat during an arson fire. some mattresses were set on fire, it was a semi enclosed area
There is other areas that are just as black or less black with soot about 125x70 that I did a test and can get it clean with just water & pressure but this 50x50 area was hit with the must flames & heat. Its uncoated underside ceiling smooth concrete.
I did try some of PT's concrete cleaner, didn't touch it. Could the ceiling be permanently damaged/black??????? I tried heat, concrete cleaner and high pressure and roto nozzle
Any help thanks
