In the beginning, the answer to good rinsing was to simply open the valve all the way. However, with water/energy conservation and pollution control becoming more and more desirable, not to mention required, finishers are learning to turn off the faucet, save water and recover chemicals whenever possible. And good rinsing techniques not only save water, they help produce quality parts. Submerging work in a tank of running water is how most platers and others in the finishing industry rinse parts. This dilutes the finishing solution clinging to the work by the ratio of dragout plus water flow divided by dragout. Rinse ratio = (D.O. + Water)/D.O.
