A fluid-dispensing kitchen apparatus has a body including a fluid reservoir and a handle, the reservoir being closed by an end plate which is welded to the body and is, in turn, latched to a cleaning medium block. An embodiment has a resilient tab on the block engaging an edge of the housing plate. Aligned holes through the plate and the block which provide communication between the reservoir and the plate is openable and closeable by a valve actuated by an increase in pressure provided by depressing a resilient button. In an embodiment, the resilient button includes a bias member to return the button to its rest position.
