Premium distilled water for ultrasonic record cleaner

And there's your answer (simple distilled).

Or you can be a nut like me who cleans with an AudioDesk and rinses on a VPI 17 with reagent grade water. Do not ask me if I can tell the difference without a rinse. I've never conducted that test and probably never will. Just happy to know that if the AD left any residue from the cleaning agent, I took a shot at it.

When I had the Audio Desk, I reduced the amount of factory fluid based on input from other long time users. I could still see the effects of that fluid residue afterwards- water spread across the disc fairly evenly, as if there were still a surfactant of some sort present, breaking the surface tension. Theoretically, the ultrasonic cleaning as a finishing step, without the contact of potentially polluting brushes, or static inducing vacuum wands, is best. However, I still got better results on some records by point nozzle drying the ultrasonically washed, but not forced air dried, record. One can do this without spending a fortune on machines- DIY ultrasonic plus used Loricraft will get you there. 

Has anyone tried oxygen free distilled water?  Especially the cryo-treated version?  Maybe the oxygen free distilled water that came out of the vacuum mines before the great implosion?
