"We have 900 square feet of ceramic tile in our downstairs house. The grout lines have never been sealed or professionally cleaned. The grout was once white but before we called Super Steam the grout lines were black. We tried everything under the sun to get them clean (even bleach with hours of scrubbing). We had always had our carpets cleaned by Super Steam and were always impressed with the job they do. We recalled that Bryan (from Super Steam) had mentioned that he professionally cleans tile and grout if we were ever interested. We decided to let him have a "go" at our tile. WOW!! He came in with this machine that made that tile and grout look as new as the day it was installed. The grout (that we worked sooooo hard at scrubbing) was turned white as snow. We were very impressed with the professional service Super Steam provided."
