Abstract: 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).
