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.
