Cleaning tile and grout by a professional

This is a video of how a tile and grout floor is cleaned. When done by a professional you get much better results. Once the tile and grout are cleaned you can then have the grout sealed which should be done when tile in installed but most times it is not. By sealing your grout it helps keep your grout clean because the dirt then sits on top of the gout instead of being sucked into the grout.
