Water heater: 120 degrees F. Cycle time: typically 2:15, never more than 2:45. We have really hard water so I've always used a booster (first Glass Magic [expensive, still contains phosphates], then Lemi Shine [ditto, no phosphates], now TSP [cheap in a 4½ pound box from Home Depot]).
Next time I broil Brats in the CorningWare, I'll try a load with just a Powerball tab.
