how do I clean granite floor tile?

i use lemon juice or orange juice. the fresh kind beacuase the stuff you get at the stores has alot of sugar in it and that is all you will smell 4 about a week.

I like TileLab cleaner and protectorant available at the Home Depot. You can get it in a spray applicator and use a mop to spread it. You don't have to rinse it off because as it dries it will leave a nice shine. It also leaves a protective coating on the granite which helps resist dulling over time.
