A soap dispenser (10) for providing and controlling flow and mixture of a liquid, such as water, and an agent or media, such as soap, useful in various applications, including, for example, cleaning a vehicle or other object or surface. The dispenser (10) broadly comprises a grip (12) and a body (14) in a rotatably coupled relationship, with the body (14) defining a soap reservoir (47). A first grip end (20) of the cylindrical grip (12) is adapted to connect to a water supply source, such as a common garden hose. A second grip end (22) is coupleable with the body (14) so as to be rotatable in relation thereto. The grip (12) provides a first control surface (24) having a flow channel (26). The body (14) is also cylindrical and provides a second control surface (44) having a single large orifice (46) and a plurality of flow holes (48,49), each of which is rotatably alignable with the channel (26) of the first control surface (24). Thus, the grip (12), control surfaces (24,44), and body (14) combine to provide a plurality of rotatably selectable flow paths for controlling flow rate and mixture.
