Precision Aqueous Cleaning of Vinyl Records

FYI, I have previously posted a bit of information on cleaning, and I have now complied that and much more into a paper titled “Precision Aqueous Cleaning of Vinyl Records”. Bill Hart of The Vinyl Press https://thevinylpress.com/ who has a keen interest in cleaning vinyl records is hosting the paper. He has written an article on the paper that captures it better than I could, and a link to the article that has the free-download load option for the paper (85 pages) is here: https://thevinylpress.com/precision-aqueous-cleaning-of-vinyl-records/ . If you have not been to his site, check-it out, there is a lot of good info, and its well written. While at his site, check out the about-tab and then scroll down and click on System-Notes-Austin-2017. He has a pretty impressive system and near the end shows quite a ‘cleaning station’; using both a Keith Monks vacuum-RCM and KL Audio UCM.

Best Regards and Stay Well,

Neil

My experience is as a molecular biologist. We used ethanol and acetate to precipitate DNA and RNA. SDS plus or minus Triton X100/Tween20 to solubilize cell membranes and intracellular organelles. Also there are a slew of nonionic detergents with different characteristics suitable  for isolating various proteins with specialized physical chemical properties. That was usually a hit or miss proposition.

The science of surfactants is pretty amazing - there is very little they do not touch.  Although Triton X100 is now banded in AU/EU/UK because it's an aquatic toxin.  But Polysorbate 20 (same Tween20) is still available, so the book now lists Polysorbate20 as an alternative for those overseas.  The viscosity is about the same as Triton X100, it does not reduce the surface tension as much, but its good enough and its critical micelle concentration is less so less is used - easier to rinse.

I use a Keith Monks RCM with the KM special fluid.

Wondering if it would also be good to apply the Walker enzyme treatment?

Seems like a lot of work but I think that BetterRecords uses the KM and then the Walker.
