A brush assembly releases a fluid and/or liquid solution directly onto a surface, such as a coat of an animal during grooming, or onto inanimate surfaces such as vehicles. The brush assembly includes a molded brush having a plurality of apertures integrated therein for delivery of a fluid. At least one base plate with grooming implementations, such as bristles or a sponge, is interchangeably attached to the brush base. An ergonomical handle is provided having a palm conforming top and finger indentation sides constructed to form an internal cavity. The ergonomical handle is ambidextrous in nature for interchangeable left and right handedness. A center cylinder is located within said internal cavity of said ergonomical handle and includes a bladder which aligns with the mid portion of the brush base for fluid delivery controlled upstream by a flow regulator. An optional mixing chamber housing a water soluble compound containing active ingredients may be attached to the flow regulator to form a liquid solution. The fluid and/or liquid solution is delivered directly to the surface during grooming.
