A method for forming solid cleaning agents starts with hydrated forms of salts that generally have considerably lower melting points in their hydrated forms. The hydrated salt cleaning agents are heated to form a melted cleaning suspension. Additional ingredients can be mixed into the melted cleaning suspension. These additional ingredients can be selected from the group consisting of nonionic surfactants, anionic surfactants, alkaline builders, multivalent metal sequestering agents, active enzymes, soil suspending agents, defoamers, oxygenated solvents, fragrances, optical brighteners and colorants. An alternative method involves the formation of a mixture of powder or granular cleaning composition components. These components include at least 15 percent by weight of a moderate melting point cleaning additive. A receptacle with the cleaning components is heated to a temperature above the melting point of the moderate melting point cleaning additive. After sufficient time, the heating is stopped, and the mixture solidifies into a solid cleaning composition. A class of novel solid cleaning compositions comprise at least 15 percent a hydrated melt salt cleaning agents. The solid cleaning compositions can have additional additives.
