Norge had the perfect system for using Calgon with the overflow rinse, although not so great with a cold water rinse, but the Calgon was dispensed at the start of the rinse to make the water all slippery and soft then the Calgon-rich water was diluted and flushed away during the overflow rinse. This was a short-lived device because it was almost immediately replaced by the puke-o-lator agitator-mounted lint filter and the top of the line Dispensomat had a control panel mounted flush through dispenser for Calgon so they could offer both lint filtering and Calgon in the rinse, if desired and if you bought top of the line, but that was after 1957.
