  <div><br></div>the area is outside, about 100 sqft and I have tried just about 
  every form of acid or flouride cleaner, and even mold cleaners. What seemed to 
  work the best are the acids, but they just etch off what is on the surface and 
  whats in the picture is what is left over. Also tried grinding but to no 
  avail. The only thing I can think of trying next is some form of poultice.
  <div>fiAny ideas?</div>
