We were dropping an Electrasol Tabs (Confession: Yeah, we were using Electrasol because their tins with The Jetsons on them are weirdly kids-collect-them-all cute) into the machine for every load of dishes.

Using so much soap is unnecessarily harsh on your dishes, he said. We stuck to his advice and notice the dishes don't spot and we don't have to buy detergent as often.
As our Kitchen Keeping month marches on, tell us what kind of dishwasher detergent you use. And, how much do you use? Hang in there, those of you who don't have a dishwasher. We're going to talk sink stuff tomorrow.
