Abstract: A window cleaning device of the type having a handle, a head attached to the handle and a sponge mounted in a longitudinal channel in the head of the washer is provided. A net-like web envelops the sponge. The cleaning device includes an improved stiffener having an elongate body provided with a pair of shoulders extending along the body on both sides thereof. A plurality of protrusions are integrally formed with and extend outwardly from the shoulders on both sides of the elongate body. The stiffener has a pair of flanges one located at each end of the elongate body for locating the body in the channel and preventing movement of the body in the channel. The protrusions act to compress multiple portions of the sponge between the ends of protrusions and the channel walls which creates a plurality of highly compressed areas at these points adjacent less compressed areas between the highly compressed areas into which excess sponge can flow.
