I have white spots on my new marble vanity that look like it is deep in the marble. It looks like the marble has faded but it also feels a little rough. It looks as if something was sitting on it and left a ring.
Marble is also affected by acids, so if someone was cleaning with vinegar or CLR, that could have cause the damage. I don't think there would be a way to fix it, but perhaps the marble polish mentioned might help.
I also have marble vanities (black) and have the water marks. I did some reserch and found that the water actually etched the surface. I have not found anything to fix the problem. I wipe the surface with marble polish to try to prevent more damage, I think it helps. I don't know why they use marble in the bathroom if it is so sensitive to water.
