Since they are afraid to say what it is i question them from the get go.
Their claims of removing 'contaminates' left on the surface while cautioning about ph of water leads me to suspect a 'no streaks' dishwasher soap will do the same thing.

The key is the water used... hard water is going to be problematic no matter what you do...
