ABSTRACT:
Disclosed is a composition and process for cleaning articles contaminated with water insoluble contaminants. The process allows for efficient recycling of components in the system. The wash solution effectively cleans water insoluble contaminants and, upon settling, quickly releases contaminants from the wash solution. In this manner, the wash solution and components of it can be readily recycled. The composition of the present invention includes between about 1.86 volume percent and about 37.2 volume percent terpene, preferably d-limonene, and between about 0.14 volume percent and about 2.8 volume percent surfactant.
