The present invention relates to a method of manually cleaning dishware using a liquid hand dishwashing detergent composition comprising an anionic surfactant and a cationic polymer having a MW below or equal to 2,100,000; and a charge density above or equal to 0. One outer layer functions as the primary adhesive layer for adhering the patch to the host. Fasteners are removably secured between adjacent rails and maintained in a predefined orientation by the adjacent rails. The switch functions to connect an input resistance on the first branch and disconnect the digital-to-analog converter during the first phase, and disconnects the input resistance and connects the digital-to-analog converter during the second phase.
