I saw a tip that everyday household vinegar will keep film off dishes without leaving a vinegar odor, and I tried it tonight. It worked beautifully! Just pour the vinegar where you would the Jet-Dry (gosh darn, that stuff is expensive!) and set the cycle as you normally do. My glasses look better with vinegar than they did with rinse agent.
