Abstract:

A method is taught for cleaning photographic chemistry product fouling, including a proteinaceous portion and a non-proteinaceous portion from a liquid delivery system. The method comprises the steps of displacing resident product solution in the piping with water, hydrodynamically cleaning the piping system using two-phase flow a first time, chemically cleaning the piping system with an aqueous bleach solution to remove the proteinaceous portion of the photographic chemistry product fouling, chemically cleaning the piping system with a functionalized ethyl acetate solvent to remove the non-proteinaceous portion of the photographic chemistry product fouling, and hydrodynamically cleaning the piping system using two-phase flow a second time after the chemical cleaning steps to remove remaining residue. Preferably, after the second hydrodynamic two-phase flow cleaning step, the delivery system is subjected to a high purity water rinse.
