Abstract: A washer and dryer sheet having a substrate including a first visual indicator, a washer composition including a second visual indicator, wherein the second visual indicator is removed during a wash cycle, and a dryer composition including a third visual indicator, wherein the third visual indicator is removed during a dry cycle. Also, a method of washing a drying an object, the method including disposing a washer and dryer sheet having at least two visual indicators in a washing machine, contacting the object and the washer and dryer sheet with waster, removing the washer and dryer sheet from the washing machine, and exposing the object and the washer and dryer sheet to a heat source.

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.
