ABSTRACT:
A dispensing dish brush includes a cap, a handle portion and a cleaning head. The cap and the handle portion define a common wall that defines a reservoir. The reservoir stores and dispenses a cleaning liquid. The handle portion includes a gripping portion and a neck portion. The gripping portion includes a core section, a middle section and an upper section that define a diaphragm. The neck portion has an extension portion that connects to the cleaning head. The cleaning head includes a plurality of bristles and an aperture with a wall. The aperture is placed with a removable valve and valve lock to restrict the flow of the cleaning liquid. The diaphragm is squeezable and flexes to dispense the cleaning liquid. The diaphragm accelerates the flow of the cleaning liquid in the reservoir. The cap provides access to the reservoir.
