The Steam Team (http://www.thesteamteam.com/austin-cleaning-services/upholstery.shtml) utilizes high pressure steam to both dissolve and force dirt out of the dirty tiles. Why does it get so dirty? Tiles are usually in areas that receive high traffic in your home (people and pets walk on them a lot).
The Steam Team can handle various types of tiles, such as marble, granite, limestone, travertine, slate, sandstone, flagstone, terra cotta, clay, concrete, masonry, ceramic, and porcelain.
Some stones can be cleaned, polished, sealed, and have their color enhanced so they look brand new again. Each type of tile has its own requirements and methods to clean.
The Steam Team has been around since 1983. They offers such services as carpet cleaning, upholstery cleaning, air-duct cleaning, water extraction, restoration, and many others. Green services include using environmentally safe chemicals that are non-toxic to humans and pets.
Speaking of pets, have you ever noticed that major pet accidents can seep all the way to the padding underneath the carpet? If not caught in time, the urine could actually seep through the floor and spread bacteria. The Steam Team can help rectify such situations.
