I have had semi-shiny light tan ceramic floors in the main part of my home. I sweep, spray with Windex or homemade Windex and mop with a damp (not wet) microfiber mop. I start out in a corner and mop away from it backing up. If it was really dirty I rinse my mop and damp mop again. You have to let the floor dry before you walk on it or it will leave footprints. It only takes a few minutes to dry. This is the only way that I can come out with a clean, not cloudy floor. I have done this for over 35 years and my floors look great. I have never sealed my grout. I chose a dark stained grout in the beginning and have never needed to seal it.
