Cleaning your porcelain tile is not like cleaning other surfaces. This is because porcelain tiles fire at a much higher temperature than the average ceramic tile (2,300°F apposed to 1,800°F) which drives out more water, making a stronger structure. The unique ingredients used to make porcelain will cause it to form into a low-order glass, making it extremely water resistant. This makes the tile become more stain resistant, as well as not allowing dirt to penetrate the surface; however, it is still necessary to remove the dirt and grime from the top of the tiles.
