Abstract: A fluid dispenser apparatus for use in cleaning surfaces of electrical printing apparata, among other surfaces, is provided for exchangable attachment to a fluid container. The apparatus includes a removable tube for extended and directed delivery and placement of the fluid, on the surface being cleaned. An applicator plate, supporting a densely formed, replaceable sponge, is located at the end of the tube to collect and help keep the fluid in a liquid state to facilitate application and scrubbing therewith. A pushbutton valve permits selective, variable control of the flow rate of the fluid. A vent may be alternatively provided to improve back pressure in the fluid dispenser apparatus and improve its dispensing characteristics. The apparatus is configured for facilitated assembly and disassembly for facilitated cleaning of the pushbutton valve.
