Each of the tablets is encased in a pouch that looks like it's clear plastic, but don't try to open the pouch. It's actually made of polyvinyl alcohol (PVA), a biodegradable polymer. The pouch is simply part of the tablet, and will disintegrate as the wash cycle starts. The package warns you not to touch the pouch with wet hands, since the pouch will start to disintegrate upon contact with moisture, and will actually stick to wet hands.
To use the tablet, simply open up your main dispenser cup on your dishwasher, pop the pouch in, and run the wash cycle as usual. I found the Seventh Generation Automatic Dishwasher Detergent Pac very easy to use. But how well did it get my dishes clean? Find out.
I usually use gels, instead of powders, in my Bosch dishwasher. However, I found the detergent pacs to work well in my machine. There was no residue on my dishes or on my glasses, and everything was perfectly clean. I'd definitely recommend this product to others who are looking for an alternative to gels, or for single-use products.
