Abstract
A cleaning composition includes a liquid vehicle having dispersed therein, a particulate, organic, polymeric material. This composition is used for cleaning encrustations from the interior surface of tubes or other vessels, particularly those of paint delivery systems. Such cleaning is accomplished by maintaining a flow of the cleaning composition through the vessel. The vehicle may comprise organic or inorganic solvent mixtures and may include detergents, surfactants and similar ancillary ingredients.
