It's a looooong thread, but again, nothing wrong with you doing it, at all.>I clean all LP's with vacuum irrigation - purpose-made Disc Doctor surfacta= There's more to this in terms of changing the surface tension of water, thermodynamics,micelle formation, solubilization of non-oily contaminants, etc., but this is a simple explanation of what I think you were asking.Ī later posting states acceptability at below 15% with a surfactant and quats. Considering this, and their higher effectiveness at solubilizing oils, detergents are the preferred choice for cleaning records.
The longer chain detergents do not extract plasticizers.
The plasticizers in PVC that give the plastic its properties are soluble in lower alcohols like IPA so they are not recommended (Scientific studies from preservationists have demonstrated plasticizer removal falls as you get below 50% IPA, but it is assumed some may get some extraction at all concentrations). Change the polar alcohol group in these long chains to a carboxylate, sulfate, ester, or other group and you get soaps or detergents that are much more effective at solubilizing oils. Similar compounds with longer non-polar chains (higher alcohols) are even more effective at solubilizing oils.
The saturated carbon chain of IPA is short and branched. On the other hand, the polar alcohol group of IPA likes to be in water, so you have a compound that bridges the non-polar and polar, hence solubilization of the oil. Oils are comprised of molecules with long carbon chains and "like dissolves like", so the non-polar groups prefer to be with other non-polar groups in an aqueous solution. It is effective on certain oils as it has a non-polar region (carbon chain) and a polar end (-OH group). I'm currently in a deep dive on record cleaning and various aspects of it, and read this in the last week. I wipe the mess up with microfiber towels. The surfactant may not be important, but we use the very same thing at work to wet down asbestos due to its ability to get into microscopic crevices, so I suppose that it won't hurt here. My lasting regret is starting with digital, but that's what I had when I started, so.ġ part 91% isopropyl alcohol, 4 parts distilled water, and one small part (a few drops per spray bottle) of liquid dish soap as a surfactant. I hate you fucking guys, but I mean this in the nicest way possible. I realized a few days ago that I'm probably going to have to sell my Gungnir Multibit, and probably most of my headphones as well. One thing at a time, right? I'm just enjoying the hell out of this ride right now. The folks with more expensive stuff may be on another level of nirvana, and if so, I will achieve that enlightenment eventually. If this is wrong, I don't want to be right. I'm new at this, and I'm listening via a low end Technics and Mani, through homebuilt speakers.
