Great post! I've read other posts about dishwashing detergents and many of us only fill one of the dispenser cups, effectively giving dishes an extra rinse instead of two washes, and I have to agree with you that they're very concentrated. Using just using a quarter of the recommended amount of detergent still washes them very clean. Also, I fill the Rinse-Aid dispenser with vinegar instead. I wonder if the "green" detergents from the health food store are just as bad. Hmmm.... very interesting post, Thanks!!
