<p>An improved method and apparatus for cleaning liquid-carrying hoses (12), and the like. A suitable cleaning solvent (20 or 22) is passed under pressure through the hose (12). The pressure of the solvent delivered to the hose is measured and used to control the pressure of compressed air (30) mixed with the solvent to maintain a turbulent flow of a predetermined mix ratio for various solvent pressures. The turbulent solvent/compressed air mixture increases scrubbing of the hose to reduce the cleaning time and the quantity of solvent required to clean the hose.</p> |
