How much isopropanol is effective but safe for viny?
@boxer12 I use Triton X-100. Photo Flo is also good. https://www.amazon.com/Triton-X-100-Surfactant-500ml-Purity/dp/B009RZZB76/ref=sr_1_1_sspa?ie=UTF8&am... |
I think I would limit the definition of a surfactant to a substance that reduces the surface tension of a liquid in which it is diluted, in this case of water. This allows the water to be "wetter", to penetrate better. Whether this also results in faster drying may be true, but I am not so sure it's a good thing, if so. If water plus surfactant (usually a nonionic detergent) dries, then it leaves a residue. In addition to isopropanol, my RCM concoction also includes a few drops of surfactant per gallon or so, and I usually use Tween20 or Triton X100. (I think Dawn is fine in this application, too.) But I always rinse with pure distilled water to avoid leaving a residue. My results have been better since I added the distilled water rinse cycle. |
My solution is distilled water with about 10% isopropyl and a drop of dish detergent. This is used with a very inexpensive cleaning machine. I wipe with a microfiber cloth until nearly dry. Stubborn records, the ones which still have a lots of pops and clicks, I use a lint removal brush, a drop of detergent on the record and scrub with the solution above which creates lots of sudsing. Then rinse under hot tap water and dry. Several unplayable records have been recovered to play as "very good" to "very good plus" after scrubbing. I have several records purchased as "very scratched" for between $0.05 and $0.95 which play as "very good plus".... amazed me. |
