We remodeled this bathroom a few years back, and were given the opportunity to steam clean it. Even we were impressed by the before, versus after on the tile, grout and fixtures. It’ll amaze you what some hot steam (an open window or shower fan is more than enough ventilation to keep it from turning in to a sauna once the steamer is running), and a finish of natural cleaner and sealant will do to not only look great, but prolong the life of your tile and grout as well!
