Joe: I was concerned with your comments about the recovery tube being very dark / black. Seeing a cleaner surface is one thing whereas seeing "gobs of black sludge" in the recovery tubes is another. Thanks for the clarification.
As far as the discs being "ruined with the first play" if the plasticizers were being leeched out of them, that is not true. Plasticizers are used to increase flexibility. As such, removing them from any substance that makes use of them would simply result in a stiffer, more brittle material. That's why i questioned Paul as to the length of time that these records were exposed to this solution, both in terms of application and time since first applied. Given his response to those questions, one would assume that the discs themselves were still in excellent shape.
Paul: Ultrapure water can be quite aggressive depending on what it is being used on. You should read some of Jon Risch's comments about it over at AA. Jon used to work for Discwasher back when they were a force in the vinyl cleaning industry some 25-30 years ago.
It sounds like you're really onto something here and i wish you all the best should you choose to market this product. If it works as good as is being reported, you might want to think about obtaining some type of legal documentation in terms of the formulation. That is, it might not take a too much effort to reverse engineer your product if one had funds or access to a lab. Sean

PS... I find it kind of interesting that some of the other "record cleaning solution manufacturers" haven't jumped in here to correct all of the "disinformation" that is being spread in this thread. Either they aren't aware that it exists ( and i bet that they are VERY aware of it ) or they are hoping that it will just "go away".
