It zaps dried on egg and even baked on cheese and tomato! I have an older machine, about 6 years old, without the fancy scrub cycles, etc. Our water is very hard. Before I had to not only fill the main detergent cup, and the open one, but also add detergent for the wash in-between those two, otherwise I had that unpleasant odor on my dishes and glasses. With Cascade Complete, that is all behind me. I still fill the open cup with powder, because of the hardness and iron in our water....but even just using Cascade Complete alone, it does a great job!
