Seventh Generation Automatic Dishwasher Detergent Concentrated Packs
Veteran green consumer advocate Annie Berthold-Bond raves about this product, which comes in tablet form. Seventh Generation, she said, is the most successful for my dishwasher, and after I started using [the tablets], I have never looked back. Contains no phosphates or synthetic scents. Minor filming is a problem, some say. $23 at amazon.com.
