Attack soap scum and hard water stains on ceramic tile in the shower and grease stains on kitchen backsplashes with care. Many all_purpose, commercial cleaning products are safe on ceramic tile, as long as they don't contain ammonia, acid, vinegar or chlorine. Abrasive cleansers also should not be used on ceramic tile. Many products that are advertised to be "green" should be safe, but always check the label to be sure. Buff ceramic tile that appears to be cloudy or foggy with a clean, dry cloth. Often, what appears to be dirt on ceramic is really just condensation, so buff it away to restore the shine.
In an older home, you may find the floor isn't square, which makes the job more complicated. Use the most obvious wall as a baseline, so those entering the room will see tile lines parallel to that wall; your job will look more even.
