ABSTRACT:
A cleaning system having pulverulent foaming cleanser (e.g., acid, alkali metal carbonate and surfactant) is sealed within a water soluble (e.g., PVOH) deformable pouch frictionally retainable within the core of a roll of bath tissue. Upon placement of the pouch in the bowl, water in the bowl penetrates the water soluble wall of the pouch, generating foam which provides cleaning action by activating and carrying cleansing chemicals, not only below the water line of the bowl, but also considerably above it. When used routinely with each change of bath tissue roll, such a cleaning can extend the time between required manual cleanings considerably.
