Described herein are techniques related to a magnetic tool for cleaning one or more surfaces of a plate of magnetically permeable material, such as a window. With an implementation described herein, the tool includes a pair of magnetically attracted utensils designed to be magnetically coupled together through a window. While a user slides the utensil along an interior surface of the window, the second utensil follows the first utensil and slides along the exterior surface of the window. The second utensil is tethered to a fluid pump via a fluid-conductive hose. In this way, cleaning fluid may be delivered to the second utensil while it is on the exterior surface of the window and cleaning that surface. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
