Abstract
Abstract A solvent composition for cleaning ink and other soil material from printing presses is formulated by blending together in a critical ratio higher boiling non-flammable chlorinated or brominated hydrocarbon liquid, low boiling chlorinated or brominated hydrocarbon liquid, petroleum solvent such as mineral spirits, and a compatible surfactant, such as nonylphenoxy polyethoxy ethanol. When blended together in proper ratio the blend is non-flammable, possesses desirable characteristics so as not to dry so quickly that the printer or pressman does not have sufficient time to wipe the equipment clean but completely evaporates within a few minutes after application, and is highly efficacious as a solvent for the soil materials.
