I have a travertine floor on my shower which is black with white veining. Sadly we were advised that we did not have to seal it when it was installed last fall. Now it has white spots all over it, which do not seem to respond to the few cleaners I have tried. (Kaboom was one I tried thinking the white spots were possibly soap scum, but I tried everything sparingly as I was concerned about the porous tile). Can you recommend anything to clean this with? The other tile is glazed and I would appreciate any advice on keeping it shiny and clean too. It looks clean, but I have to scrub it to keep it smooth, etc.
Thanks for your help.
