Tile and Grout Cleaning
While tile is thought to be resistant to stains and relatively easy to clean, grout is porous and absorbs dirt, grime, and harmful germs. Tile can also be covered by grease and dirt which is not only a safety hazard but also provides a food source for bacteria. Think about how many people walk on your tile floors. A study done by the University of Arizona found an average of 421,000 different types of bacteria on shoes.
