These really work!
We have white limestone tile floors (not our choice; installed by the previous owner) and they attract dirt like crazy. Nothing else gets out these marks - not the Hoover Floor Mate, not the usual floor cleaners and certainly not damp mops. I use these in combination with the Hoover Floor Mate and while my floors will never be pristine white, at least the marks are easily taken care of.
