Suggestions on servicing a limestone floor. Please see attached picture. I have a job for a condo lobby that has limestone with various finishes. So using diamonds are not a viable option. In the past I have serviced the floor with Miracle Sealants Liquid Poultice to clean the floor followed with polishing with 5X.  They have been pleased with the results in the past. But I fill that eventually my luck will run. I have noticed on jobs in the past to really clean the limestone that the surface needed to be cut. They are looking for the floor to be cleaned and polished to a nice gloss.
I would appreciate any suggestions on servicing this floor.
