Help with bathroom marble care

I desperately need your help.  My wife and (http://maplered.com) I installed a Marble (http://www.lightemprador.com) agglomeratein both of our bathroom floors.  However, we had no idea that Marble (http://www.lightemprador.com) was sensitive to acid.  (Lowe's really doesn't bother telling you this!) Two problems - my daughter got sick in the one bathroom and (http://maplered.com) now half of the tile is dull from her stomach acid.  #2 how do you clean a toilet with a non-acidic cleaner.  Overspray has resulted in dull spots on our floors.What if anything can be done to restore (and (http://maplered.com) them protect) the lusturous finish?
Thanks,
Mark Faix.
