The present invention 10 discloses a chalkboard cleaning device that is mountable to a conventional chalkboard 12 providing means for selectively cleaning parts thereof. The present invention 10 is comprised of a rail 18 mounted to the top edge of an existing chalkboard 12 having the cleaning apparatus 20 attached thereto and extending from the top to the bottom edge of the board 12. The present invention 10 is comprised of an adjustable frame 30 and sponge 20 which is trimmed at the time of installation to fit the adjusted frame size. The frame 30 has a tensioned 40 rail 18 engaging element 27 for selectively moving the cleaning apparatus 20 to a desired point to be cleaned. Once positioned the apparatus 10 has a pump 26 and fluid containing reservoir 22 in communication with sponge 20 whereby pressure applied to the pump button 48 releases fluid 54 into the body of the sponge 20 whereupon movement of the cleaning apparatus by means of the handle 24 cleans the selected area. The fluid reservoir 22 has a cap 34 for refilling the reservoir on site or the reservoir can be dismounted for refilling and remounted. Additionally, the present invention 10 provides for an alternate pump mechanism 26 wherein the fluid spray 54 is applied to the chalkboard 12 adjacent the sponge 20.
