Had the living room, dining room, hallway and kitchen floors tiled. Unfortunately, when the contracter did it, and then plastered the walls by the newly installed baseboard, some white plaster/dust/paint got into the small (1/8"), randomly placed pits in the tile (a part of the tile) and we can't seem to get it out. We've tried mopping, scrubing, paint thinner, but nothing seems to work.
The tile is not a smooth, gloosy one like you find behind counters but is more like a country french house. No idea what type of tile it is, although it is very hard and very durable, evidently. The tile shop where the tile came from has no suggestions (save for to use an eraser, which also didn't work) on how to get these white spots off of it, and the contractor, before being kicked off the job, was using what she called an enzyme cleaner or something (all of this through translation).
Any suggestions or ideas?
