Hi,i have a big house to clean tomorrow,carpets,upholstery,leather.Property management company was talking about getting 7 bathrooms,and what looks like marble floor downstairs.I have the tools but not the training so kinda hoping they did not want it all cleaned.Anyway client moving in monday and they want the marble cleaned tomorrow.....property company tells me to clean it.Kinda have to take it on.I been around trying to get a marble cleaner,,,none about...would i get away with using prochem ultrapac.Its a high alkaline,,I know iM A HACK ON THIS ONE.
