Use a clean, stiff fiber brush or other tools recommended for cleaning the surface. Flush the system thoroughly with water before returning it to normal use. Do not add cleaning agents to processing tanks unless the tanks, recirculating lines, and racks have been completely drained and thoroughly rinsed with water. Refer to the Material Safety Data Sheet for each photoprocessing solution for more information. Warning DO NOT process sensitized products while sodium hypochlorite bleach remains in the system.
Hypochlorite bleach can destroy images and reduce image stability.
Biocides The severity of bio-fouling may vary significantly. To keep out of trouble, follow recommended maintenance procedures on a regular basis. It may become necessary to use biocides in rotation. Biogrowth may become resistant to a particular biocide after a period of months of exposure. The biocide will then be carried with the countercurrent wash from tank to tank.
