Abstract: A multiuse cleaning device in a solid state containing a homogeneous quantity of cleaning agent configured to dissolve and release a substantially consistent quantity of cleaning agent over a plurality of wash and rinse cycles. The cleaning agent includes a gas-releasing component and potassium silicate as a solubility control component to limit the solubility of the cleaning agent. The cleaning agent may include other ingredients such as an alkalinity agent as a pH regulator, a water softener to solvate metal ions in a solution of water, an optical brightener, an anti-redeposition agent, fragrances, surfactants, and other ingredients. Controlled dissolution of the cleaning agent composition releases a desired quantity of cleaning agent in each cleaning cycle over a plurality of cycles. A porous enclosure may be disposed around the solid cleaning agent.

Abstract: A multiuse laundry cleaning device in a solid state containing a homogeneous quantity of cleaning agent configured to dissolve and release a substantially consistent quantity of cleaning agent over a plurality of laundry wash and rinse cycles. The cleaning agent includes a gas-releasing component, potassium silicate as a solubility control component to limit the solubility of the cleaning agent, an alkalinity agent as a pH regulator, and a water softener to solvate metal ions in a solution of water. Controlled dissolution of the cleaning agent composition releases a desired quantity of cleaning agent in each cleaning cycle over a plurality of cycles. A porous covering of bag may be disposed around the solid cleaning agent.

Abstract: A solid cleaning composition and method of manufacture are disclosed, which provide a long-term, solid cartridge made of cleaning agents and a solubility limiting agent for controlling an equilibrium concentration of the composition in a solvent, such as water. In use, the cleaning agents are dissolved only to a predetermined concentration needed for a single dose of a cleaning appliance, such as a clothes washing machine. The solid cleaning composition may be cyclically exposed to water. Controlled dissolution of the cleaning composition releases a desired quantity of cleaning agents in each cleaning cycle. The use of potassium silicate as a solubility controlling compound permits manufacture of the cleaning composition at ambient temperatures and pressures. The cleaning composition may be molded or cast into a desirable shape for controlling surface area.

Abstract: An apparatus, method, and composition provide a long-term, solid cartridge made of cleaning agents mixed at an equilibrium concentration with a solubility limiting agent for controlling an equilibrium concentration of the composition in a solvent, such as water, for example. In use, the cleaning agents are dissolved only to a predetermined concentration needed for a single dose of a cleaning appliance, such as a clothes washing machine, for example. The apparatus may be configured to cyclically expose the solid cartridge to the solvent. A dosing amount of the solvent dissolves a pre-determined concentration of cleaning agents, controlled by the solubility limiting agent. The apparatus discharges the dose of cleaning agent to a cleaning appliance, and readies itself again by dissolving a dose of cleaning agent from a surface of the solid cartridge into the solvent.
