I just received a call to look at a tile floor with black marks on it.
The person that called me is a friend that only does hard surfaces.
He said that they tried several chemicals and a 175 floor machine, but no go, he also tells me that it looks like skid marks from shoes, a cart or sometime like that.
I get there and the construction company forman says that several peoples have tried and can not remove any of the black stains.
What would you try? I do have the answer.
