I have a very old dishwasher that for whatever reason left a white film on all my dishes... I tried the other "puck" style brand but they didn't help with this problem. I switched to Cascade All-in-One packs and things are so much better!

These are so convenient for our small dishwasher. I am skeptical of their ability on truly dry, soiled dishes, but we have a small dishwasher and run it often. Dishes come out clean and streak-free, and we don't need to buy a rinse agent because it is part of the actionpac. Would recommend!
