Some film is left on some tile. I did a job Tuesday with three types of tile surfaces, and on two, I had to wipe the tile with microfiber to remove the visible residue. Not an issue, for it came away very evenly and left no discernible film. So no, it does not always magically clear itself up and yes, there is a residue (although it may not be visible under all conditions).
