Liquid-Dispensing, Effluent Shielding and Microbe Eliminating Methods

A method of eliminating microbes in an overflow space in a sink having a sink basin and at least one overflow opening in the sink basin and communicating with the overflow space may include obtaining a liquid dispensing and effluent shielding container assembly including a flexible container having a container interior and a splash guard including a splash guard shield carried by the container and an injection nozzle carried by the splash guard shield, the injection nozzle having a injection nozzle bore disposed in fluid communication with the container interior of the container and at least one injection opening in the injection nozzle, the at least one injection opening disposed in fluid communication with the injection nozzle bore; placing an antimicrobial or cleaning agent liquid in the container interior of the container; inserting the injection nozzle of the liquid dispensing and effluent shielding container assembly in the at least one overflow opening in the sink basin until the splash guard substantially covers the at least one overflow opening; and expelling the antimicrobial or cleaning agent liquid from the container through the injection nozzle and the at least one injection opening and into the overflow space in the sink basin of the sink, respectively. A liquid dispensing and effluent shielding container assembly is also disclosed.
