A device for cleaning opposing surfaces such as a truck rear cab window and opposing cap front window. An elongated shaft having a handle-like assembly which operated to open and close the cleaning assembly, thus allowing the device in its closed position to be inserted into narrow junctions between opposing surfaces and subsequently opened to an angle conforming to the space between the various opposing surfaces to be cleaned. In addition, a ball and cup mechanism allows the cleaning members to continuously adjust without manual intervention, thus permitting uniform cleaning of various surfaces. The device can also be used for other applications, such as painting.
