I have recently uncovered a quarry tile floor (red/cream & minton), but it has in recent years been carpeted with a black rubber underlay underneath.
The problem is that this has left marks on the tiles, & I'm looking for suggestions to remove them.
Have tried sugar soap, white spirit & other solvents, paint stripper - all to no avail. I'm wondering about caustic soda as a last resort - any Ideas?
