My Kenmore dishwasher came with a sample of Cascade Complete and I couldn't believe the difference. Maybe it has a bleach in it, I don't know, but it took all the old tea stains out of my tea pots. Just for kicks, I tried running the machine with my old detergent and another tea pot and didn't get the same result, so it was the Cascade Complete.

I think there are different formulations for different states. Here in the Great Lakes basin there are some detergents that are legally banned.
