Absolutely no apology needed for posting an excellent link, all I said was that it was referenced from the other link.. Given my interest, I had seen it before, but have to agree that Justin Time's "water thread" is one of the best threads ever on the subject of pure water for record cleaning, really detailed information!
I feel I should apologize if some of my posts have a commercial tint to them, I'm sure I'm guilty of being over-enthusiastic in wanting everyone to experience how good ultrasonic record cleaning results can be!
You are lucky to have access to free lab water, and no doubt powerful microscopes so you could look closely at record grooves before and after cleaning! I have a 220x Dinolite USB scope, it's not powerful enough for looking really closely at record groove walls, but can be useful for looking at general cleanliness and seeing skips and damaged lands.
None of my cleaning processes use any alcohol. I know some people use it, and I purchased a bottle of 99.9% pure isopropyl ($18 from Amazon for 2 pints) to experiment with cleaning mixtures (on my own records). Yes it's effective, but there is divided opinion on the long term safety of using cleaners with alcohol on vinyl records, with concerns about how they might affect plasticizers. Ultrasonics are so effective (helped by a mild surfactant in the Audio Desk cleaning solution) that alcohol really isn't needed.
LOL about Recordgenius, my wife came up with the name Record Genie, inspired by our Diaper Genie, and the URL was available, so that was it!
I've still got some of my NERL water left over, so I may go back and do more testing (plus customer evaluation) in the Klaudio cleaners, and let's not forget that audiotomb has 5 gallons of NERL soon to arrive which he will hopefully report on!
