Yes, you can use stripper on a natural stone floor (as this is not in the acidic group). I highly recommend testing in an inconspicuous area to be sure but a light strip should be fine.
DO NOT LET THE STRIPPER DRY ON THE TILE.
Stick to a hogs hair or white pad and be ready for the possibility that you may have to polish the floor after you have stripped it completely bare.
Hope this helps
