Optical device and a method for cleaning an optical surface on an optical device. An optical device (300, 500, 600) has a device body (302, 502, 602) and at least one optical surface (306, 310, 506, 510, 606, 610) on the device body (302, 502, 602). At least one access port (340, 540, 560, 640) on the device body (302, 502, 602) is at a location on the device body (302, 502, 602) laterally spaced from the at least one optical surface (306, 310, 506, 510, 606, 610). At least one guide channel (350, 550, 570, 620) extends through the device body (302, 502, 602) from the at least one access port (340, 540, 560, 640) toward the at least one optical surface (306, 310, 506, 510, 606, 610) for guiding a cleaning fluid injected into the device body (302, 502, 602) through the at least one access port (340, 540, 560, 640) through the device body (302, 502, 602) to the at least one optical surface (306, 310, 506, 510, 606, 610) to clean the at least one optical surface (306, 310, 506, 510, 606, 610). The optical device (300, 500, 600) can be an optical pointing device such as an optical computer mouse (300, 500, 600), or another device having an optical surface to be cleaned.
