Marble floors and floor tiles are unfortunately not as impermeable as you would expect. Although marble is a firm stone, there are products that can harm it. For spot cleaning your marble floor tiles, a damp sponge and a small amount of washing up liquid should be all that you need. You can purchase a professional marble polishing kit. However, they are expensive and you can polish your marble floor tiles just as effectively with items you have at home.
