The best way to clean and polish marble floors is to use a damp mop or cloth to remove any dirt, dust, or debris from the surface of the floor. Then, mix a few drops of dishwashing soap into a bucket of warm water, and apply the mixture to a clean cloth. Wipe the floor with the cloth to remove any remaining dirt or stains, then rinse the floor with clean water and dry it with a towel. Finally, apply a small amount of marble sealant to the floor and buff it with a soft cloth.

You can't. Polishing marble floors by hand is an incredibly labor-intensive and time-consuming process. It's also a process that's best left to the professionals, as it can be difficult to get the results you want without proper experience and equipment. Instead of trying to polish your marble floors by hand, consider hiring a professional to do the job for you. They'll have the experience and equipment necessary to get your floors looking their best in no time.
