What is the best way to clean marble tile?

Clean up spills right away and be sure to keep it free from routine dust and dirt. Sweep up the floor often with a soft bristled broom or vacuum it to pick up any loose dirt. Occasionally wash the tiles with lukewarm water and wipe dry with a clean cloth. Wiping the surface with a damp chamois will not leave streaks, but if its a large surface just get a towel. Once or twice a year, depending on soil, wash with a mild detergent solution (hand dish-washing detergent and warm water), rinse and wipe dry with a towel.  more
