Cleaning a certain tile with a side by side machine. Help Please.

Craqerzrus

I own a maintenance contract with a medical office who has asked me to clean their tile. I usually only do stripping and waxing with the side by side to scrub the floors so im not too confident in how I should approach cleaning this tile. Could someone please recommend which chemical based product for the cleaning and also the pad or brush which I should use on the machine. This tile is fairly new, about 4 months and has crevasses which tend to trap dirt. Any other useful information would also help. Thank you.
