Earlier I posted about eco-dishwashing detergents. After much testing, and three months of back-and-forth, I have determined that the winner is........ Seventh Generation powder automatic dishwashing detergent.
This stuff works great, and when we're going through Richmond we can stop at Ellwood Thompson's and pick it up in bulk.
Also, never, ever buy Mrs. Meyers for cleaning dishes. All that aromatherapy on the dishes is just a terrible idea.
