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.
