These work perfectly in our dishwasher. Every dish always comes clean. I love that it is a natural product that cleans very effectively.
I found this product did not work well for me, it was about the same as the major brands (Cascade and Finish). It left behind reside on my dishes (despite using a natural rinse agent) and left food on the dishes. I find that Seventh Generation and Method dishwasher tabs work way better than this product!
I love Nature Clean products in general but this is great. It works amazingly well... even better than other major name brands.
