Q.We would like to clean our great grandparents' 55-year old Marble Mausoleum that has black mildew on it. Please tell us which cleaner to use. Thank you, Mickey Ann

A.Hi Mickey Ann,

Without seeing and testing the monument I cant say.You can always start with a  brush and a high alkaline cleaner like mb-2 rinse well and then use mb-9 for the mildew. A cheaper way would be to use chlorox mixed with water. One part chlorox to three parts water.Test on small area first.Let the product dwell on the surface and then rinse it off.If it begins to work you can even make the dilution stronger.Just remeber to aleays test first.
