chosen: Any kind of paint or varnish can be extremely difficult to remove from marble tiles, as can oil and certain types of sticky substances. Certain cleaners and chemicals can etch or damage the surface of the stone, so care should be taken when looking for ways to clean them. Professionally applied tile sealers can be effective at helping reduce the absorption of certain kinds of substances on the surface, but some may still be hard to clean.
