Purosol, Purosol, Purosol.
Green label. B&H optics. No streaks. A lot of the other formulations either have water or are hydrophilic and pull water out of the air. That's your streak. Breath moisture is OK too but to get it done, get Purosol.
And yes I tried Dr. Clay's. He's a great guy but I'm amazed he gets more publicity that the cleaning advice on the astro-physics home page.
