Abstract
The invention provides a process for preparing a homogeneous, urea-based, solid cleaning composition, without the application of heat from an external source to melt the urea. Cleaning compositions for use in warewashing and cleaning hard surfaces, rinsing, sanitizing, deodorizing, and the like, made by the method are also provided. Preferably, the ingredients are processed in an extruder, and the mixture is extruded directly into a mold or other packaging system for dispensing the detergent. The consistency of the composition ranges from that of a fused solid block to a malleable article.
