I am trying to help someone who has moved into an old house which has marble floor (huge tiles ~4' x4'). The marble is dirty and stained all round (looks like dirt or dirt on oil which has 'baked' over time) - continuously around the skirt of the house (from the base of the skirt to up to 2 inches) and randomly like so :
I made a mixture of cooking soda and hydrogen peroxide and it has helped git rid of the corner stains. Because of the nature of this mixture, I can't pour it in a spray bottle as the soda will block the pipe. I have about 3000 square foot to go so taking a pad and scrubbing such a large area is out of the question. What is the easiest way for me to get this marble clean ? It will be very helpful if I can make the cleaner at home.
