Abstract: Disclosed is a method and system for the efficient recycling of components involved in removing water insoluble contaminants from the surface of articles. A physically emulsified terpene-containing composition is applied to the surface of articles to effectively remove water insoluble contaminants. Following application, the physically emulsified composition quickly separates, releasing the contaminants and terpene from the water. The water, terpene and contaminants are separated for reuse in accordance with the present process. The physically emulsified composition includes between about 2 weight percent and about 40 weight percent of a terpene in water.
