Hi, I am the Assistant Administrator for the Lowell Historic Board (architectural review board) in Lowell, Massachusetts. A staff person from the Planning Department of the city approached us about appropriate ways to clean marble. (City Hall has a couple of large sections of marble incorporated into the wall.) I told them I would contact the list and see if you all had any experience/ideas for us. (Especially in light of the discussion I briefly saw about cleaning David.) Thanks in advance!
