Good grief! Ask an old-world, hands-on, enologist. WaynerN, you are on the wrong track but the good thing is that you are going the right direction.
Vinegar is the natural extension of wine. Wine is hard to make but vinegar is so easy. The hard part is stopping vinegar from being made. Does vinegar help records? Yes. But not the way you think.
Wine is made from a fermentation process. Yeast munches sugars and grape skins are their vitamins. For what it is worth: 18° brix makes a safe wine with 10% alcohol. Yeasts eat and pee out alcohol. Unless unnaturally stopped, a “stuck fermentation,” ALL SUGARS ARE CONSUMED.
Normally, we stop at wine. We bottle it without oxygen and add a very small amount of sodium or potassium bisulfate to stop any growth. But sometimes we let it go wild.
Anything with alcohol in it, nix the sulfates, when exposed to air wine naturally picks up airborne acetobacter bacteria. Or simply add some vinegar to wine to hasten the process. It is a triad: with acetobacter, oxygen, and alcohol, we soon get vinegar. Miss one or add a too much sulfate and there is no vinegar.
Don’t believe? Easy to test. Go leave an open bottle of wine out for a week then take a large swig of it and gag. If you are not that brave then make oil & vinegar dressing.
About our records.
White vinegar with a potent 5% concentration has a pH of around 2.4. The pH of dishwater soaps hover around 9.0 to 10.0. The balance point, neutral, is pH 7.0. With equal mixes, soaps are neutralized and we end up with a weak vinegar solution that tastes ghastly. The way audiophiles make their solution; adding vinegar in your proportion means no soap and a lot of vinegar.
BTW, pH only applies to aqueous solutions, so pure alcohol has no pH.
But the vinegar does have desirable attributes. Used to clean hard and synthetic materials like vinyl. The vinegar has positive ions. The ions securely bonds with negative ion vinyl. End result: vinegar cleans, strengthens vinyl, and the excess positive charge actually pushes away the positive charged airborne dust. We want that.
Your vinegar proportion is strong. It is okay but wasteful and there are better ways but this does work.
People consume too much alcohol. Alcohol in our beloved standard DIY record cleaning solution, having no pH which is the fancy way of saying it has no cleaning properties, is more of a soul-satisfying surfactant even when used in excess. Efficiently, we want it in our grooves, not all over the record. It is okay but wasteful.
Bottom-line: your vinegar additive does have helpful uses but not the way you expect.
