Great question. Not natural stone, not marble. It's not shiny or
smooth like the normal bathroom ceramics. It is hard as hell - haven't
seen it scratch at all, including dragging furniture across it.
Probably a little late in the game, but you should have let the
contractor that caused the problem fix it. She was on the right track
with the enzyme cleaner to start. If that didn't work a dilute
muriatic acid with plenty of ventilation would be the next step.
Dental picks would be useful.
I couldn't. She has screwed up most everything here. Laid a wooden
floor - the boards split. Put in stone tiles in the bathroom - cement
has cracked. Couldn't get the cement walls in the bathroom right -
ended up painting over them. Electric wired incorrectly. Here's hoping
the hallway ceiling storage doesn't come down on our heads.
Would you happen to know what type of enzyme she might have been using?
There appears to be a faint white coating over the tiles that she was
washing away with the stuff. In places where her worker went over it,
it is lighter than the surrounding tile.
Understand the muriatic acid. Thanks for any continued input.
