Dispensing apparatus including a storage element having a reservoir sized for holding a supply of surfactant and an outlet through which surfactant is drawn from the reservoir; a metering device operatively attached to the storage element outlet for measuring an amount of surfactant; and a siphoning tube operatively connected to the metering device. The siphoning tube is operatively connectible to a toilet overflow tube so that the amount of surfactant measured by the metering device is dispensed into the toilet bowl when water passes from the overflow tube to the toilet bowl to refill the toilet bowl.
