How do i take care of italian marble and vitrified tiles?
Well, vitrified tiles are glass tiles so use glass cleaner (see marble also) . For the marble, I hope you’ve used a sealer on the tiles and the grout. Marble, slate, adobe tiles & grout are porous and need to be sealed regularly. I have a lot of marble tiles in baths/kitchen and I sealed them right after installation and I re-seal them with another thin coating about 2x a year. The sealer is a milky thin liquid applied very sparingly (no drips) with a sponge and let air dry between 2-3 coats. You can get a matte, satin or gloss finish.
