I finally got my kitchen tile floor cleaned professionally, and it looks brand new. The grout lines went from dark gray back to their original beige, and the tile itself lost that dull film. No more sticky spots near the sink, just a nice matte finish that doesn't show every crumb. Worth every penny.
