    Abstract: A tile sponge is provided for cleaning the space between adjacent tiles in the installation of all tile applications. The tile sponge has an elongated flange comprised of a flexible material such as rubber that extends outwardly a predetermined distance intermediate the sponge absorbing material. The flange is sized so as to fit snugly into the space between the tiles to remove material therein while, at the same time, the sponge material can be in direct contact with the edges of the adjacent tiles to soak up liquid on the tiles as the sponge progresses along the space. The lateral cross section of the tile sponge may be a parallelogram where the internal angles are other than 90 degrees.
