Try lemon juice in the extra rinse aid area. We use that as a rinse aid and it works. It's acidic and doesn't allow any metal deposits to settle on the dishes. Switch to a environmentally friendly detergent (without harmful phosphates). I know there are not many out there, but Costco now has their own, and Trader Joes has one. Then you don't have to worry so much about ingesting the deposited detergent and it won't harm the ground water. If you can find it use Lemishine mixed in with the detergent. I was given some by a friend and haven't been able to find it since. But that worked great. Good luck!
