We cleaned a travertine/limestone floor and left turbo hybrid rings in some areas like corners. I went back over with tile brushes on a crb to no avail. I have a cimex and both beige and gray pads. Is that too aggressive for travertine/limestone tile?
The tile looks ceramic, but it fizzed with the acid test. The architect said it was limestone travertine. I've never seen travertine without the tiny holes. My guess is that it is limestone that they call travertine to help sell. If it is a natural stone, will scrubbing it with a cimex and gray pads harm it? You can see how neglected it was. I am sure any sealer had warn off and it had not been cleaned in years if ever with anything other than a mop.
