Both the processed film and the seasoned working tank solution will be cleaner. This means less maintenance and less frequent dumping of working tanks. Because the new final rinse contains no stabilizing agent, labs will not need to provide formaldehyde training or do the associated record keeping required by OSHA guidelines. Then dump and rinse the working tanks, and replace the working tank and replenisher at the same time. Although you can replenish with the new final rinse on top of working stabilizer tanks, we recommend starting fresh with new solutions to gain the immediate benefits provided by the final rinse.
Final rinse is supplied as a one-part concentrate for easy mixing.
When mixed according to directions, the replenisher is the same as the working tank solution. Yes, use the yellow fill line on the label of the Film Water Measuring Bottle just as you do now. Follow the mixing directions supplied with the final rinse. No, you don't need to change your current replenishment rates. Do not process films of older design that require a stabilizing agent for image stability.
