Don't use commercial products on them as they all build up over time and leave a haze. use simple white vinegar and distilled water. Add 1/4 cup vinegar to a spray bottle and fill the rest with the distilled water. Spray lightly and use a terrycloth or microfiber mop to damp mop.
IF your floors are properly sealed you can also use a steam mop for bigger messes, but for periodic mopping the vinegar/water works very well and doesn't leave a haze. It's the only thing I'll use now.
