Abstract: A bathtub self-cleaning system includes a series of pop-out spray nozzles designed to be arranged about the confining walls of a bathtub and the like. The spray nozzles are connected by a manifold to a combined concentrate and dilutent mixing control valve. The control valve serves to initially mix the dilutent such as water with the concentrate such as a detergent to provide a diluted cleaning solution. Subsequently, the control valve discharges the cleaning solution via the manifold through the spray nozzles. The spray nozzles when popped-out are directed at the surfaces of the confining walls for their cleaning by the cleaning solution. Upon consumption of the concentrate within the mixing control valve, only dilutent is discharged therefrom to rinse the confining walls of residual cleaning solution or dirt. In this manner, a bathtub may be automatically cleaned without the necessity of any manual scrubbing thereof.
