Years ago.our 1959 RCA Whirlpool FP-50 portable top loader with the Filter Stream
wash system got the dishes cleaner than ANY dishwasher I had ever used. When I used Calgonite (the 12% phosphate formula ) and not the later 8.7% Formula 211 Calgonite with the bonus solid rinse aid,the dishes gleamed like they were buffed with an electric polisher-I kid you not. Consumer Reports was right about that dishwasher,they check rated it and its built -in counterpart as cleaning all but a relatively few test dishes to a "gleaming radiant sparkle." Its cycle design was rinse,wash.rinse,wash,rinse,rinse,dry. The main wash alone was 15 minutes long,triple the time of most machines then with their puny 5 min.wash,then two 1 min.rinses. Yet the cycle was only 45 minutes long,since it did not pause to fill or drain,but kept the motor running all along til the dry cycle which was only 13.5 minutes.How I forgot to bring this DW up a few days ago is beyond me-business I guess,BTW,the built in version had the telephone dial.
