Since we were too busy at home recently and the house is getting dirty, we decided to find a cleaning co to help clean the house on an as needed basis. The ladies that my wife found on yelp came and spend a lot of time cleaning. They did a good job except they uses something that etched the marble floor in the bathroom. They denied using anything but water but there're now shoe marks and bottle marks on the floor. I lived in this house for 8 years and at night I'd go barefoot to not wake up the family, so I know the floor pretty well and we always use only water to clean. I called a couple company and they have minimum job of $300 or $400 to come out (although they will give free quote). The floor seems to still "seal" as water sort of not get absorbed into the stone or behave differently on the "etched" part of the floor. I want to know if I can polish the mark out myself and if I do, do I need to seal / coat / impregnate the floor again after polishing? How good will the result be if I only use a car polisher. What products work or not work? Thanks.
