Bleach delivery system and method for toilet biofilm disinfection
Cleaning tools for cleaning toilets, particularly the interior of a toilet bowl, where bleach is provided within the cleaning tool itself, e.g., in a disposable, single use cleaning head. The tool may include a handle, a cleaning head attachable to the handle, a nonwoven material having an exterior surface and an interior surface, and a solid cleaning composition stored adjacent to the interior surface of the nonwoven material. The solid cleaning composition includes solid bleach, and may also include a solid surfactant. The cleaning composition may be confined within the nonwoven material (e.g., in a pouch), but upon contact with water, dissolved cleaning composition is able to migrate through the nonwoven material, through a scrubbing layer, and be delivered to the surface being cleaned. Release may achieve at least a 3-log reduction in Staphylococcus aureus within 5 minutes.

(a) a handle;
(b) a cleaning head attached to or attachable to the handle;
(c) a nonwoven material having an exterior surface and an interior surface; and
(d) a solid cleaning composition, stored adjacent to the interior surface of the nonwoven material, the solid cleaning composition comprising:
(i) a solid bleach; and
(ii) a solid surfactant;
wherein the cleaning composition dissolves in water and releases from the nonwoven material to achieve at least a 3-log reduction in Staphylococcus aureus within 5 minutes.
2. A cleaning tool according to claim 1 , wherein the solid bleach comprises sodium dichloroisocyanurate.
3. A cleaning tool according to claim 1 , wherein the solid bleach comprises a dichloroisocyanurate, a trichloroisocyanurate, calcium hypochlorite, magnesium intercalated bleach, a hydantoin, a cyanuric acid, a solid peroxide or a combination thereof.

(d) a solid cleaning composition, stored within the nonwoven pouch, the solid cleaning composition comprising:
(i) a solid bleach; and
(ii) a solid surfactant;
wherein the cleaning composition dissolves in water and is released from said nonwoven pouch to achieve at least a 3-log reduction in Staphylococcus aureus within 5 minutes.
