The device is a brush (1000) which includes an extrusion (1002), having cleaning elements made from silicone foam rubber material attached to it. The free ends (2002, 2004) of a sheet (2000) each define a flap of the brush.The sheet (2000) of silicone foam rubber material having two free ends (2002, 2004) which can be attached to a core member such that the two free ends extend away from the core member to form flaps. The solar panels can be cleaned by brushing the solar panel surfaces with the flaps of silicone foam rubber material. The solar panels can also be pretreated by brushing the solar panel surfaces with silicone foam rubber material.
