Cleaning tile floors?

The best thing for tiled floors is a good mop and boiling hot water. The tiles will dry very quick & leave no streaks. Then you can add a small amout of any floor cleaner and do the same again. as as you have just moved in , sure it might take a few washes to get them how you won�t them. I have ceramic and marble tiles all over my house. I normally just use boiling water and no detergents. Bleach will only fade the color of the tiles. Congratulations & good luck , hope all goes well.
