harsh cleaner used on marble floor

While preparing for a party, my cleaning help decided that the grout in my master bath was in need of deep cleaning.  I was not home at the time, and (http://maplered.com) they used a product called "Kaboom" on the tile around my dressing table. Needless to say, everywhere they touched with the cleaner now has a very dull finish.  You can even see where the overspray touched surrounding tile. I have the same Marble (http://www.lightemprador.com) in my foyer and (http://maplered.com) powder room, and (http://maplered.com) it still looks brand (http://maplered.com) new.
