I've used Fabuloso exrensively. Great on floors (tile, linoleum), washing down the inside of my refrigerator, in the bathroom, I even use it for clothes washing. (I like its' lavendar scent). I wouldn't worry about using it on marble. Marble is quartz, stone. Good luck and let us know how it works out!

I don't find it to be a very effective cleaner. Water alone would do as well, but wouldn't smell as good.

I'd clean it with a simple microfiber mop and water. No chemical products means no damage, no streaking or dulling of the shine. Get one with a really wide mop head since you have so much area to clean...it will really cut down your mopping time. Most swivel at the base, so you can still get into narrow spaces and under furniture.

Marble is NOT quartz (as stated above). Marble is calcium carbonate/calcite/CaCO3. Quartz is a silicon-oxygen crystalline mineral. They are not at all similar and will react very differently to chemicals. Quartz, due to its strong molecular structure, can tolerate more kinds of cleaner than a soft rock like marble. Use only a cleaner that says it is safe for porous, soft rocks like marble.
