Guys, using vinegar enhances the growth of mold/fungi. Vinegar grows a "mother" of green mold on it once it's exposed to air. That's why you MUST place boiled cheescloth over your pickle crock while they are "pickling" in vinegar, or your pickles will rot with mold.(Helps to know how to make things as they did 150 years ago!) You should use a very mild solution of baking soda and distilled water (1-3%) to keep mold at bay. Alabama, Eastman Kodak's Photo-Flo or Illford's film wetting agent won't affect vinyl at all. At least not for the 75+ years Photo-Flo has been in use. The first color movie film (NOT Technicolor "Slow Process" but Dreyfus, 1922) used clear vinyl as the film base. Bad choice. The film based streached in projection, but the emulsion didn't and the emulsion flaked off. Color emulsions cound't be coated on cellulose nitrate film bases becasue the color emulsions reacted with the nitrate in the base. 10 years later, Eastman Kodak perfected cellulose acetate "safety film". Photo-Flo is such a gentle and pure anionic detergent, it's used in cataract surgury (for both of my eyes!). It's used as a wetting agent to slip the replacement soft lens into the eye. You're awake during the procedure, and I was asking my Doctor all kinds of questions, which he happily answered for me. He was glad that I was that interested, and helped teach his students that observed...he even commented to the students "YOU should be asking Mr. Earp's questions!" I've run chemical analysis on many record products with the gas chromatagraph and mass spectrometer at the former Cities Service Technology Center in Tulsa. Guess what? The "surfactant"(detergent) most of them use is either Photo-Flo or one of it's "first cousins" chemically. I'm personally convinced the commercial record cleaning product makers put the "Photo-Flo" rumour out very deliberately to make you pay $70 a liter for what you can chemically duplicate for a little more than $2 a gallon. (1 Gallon distilled water at the supermarket was .84 cents today. 3.754L. 16 ounces of 91% isopropyl alcohol was $1.59 An 8 ounce bottle of Photo-Flo200 is $5.96 from B&H photo in NY City.(you need a 1% solution of it) and glycerin was $.59 cents in the drug aisle for 4 ounces, and you need 2-4 drops per liter for the "groove lubricant/record protector". Some record cleaning solutions use a silcone suspension for a "lubricant/protectant" that's 4-8 drops per liter of cheap vinyl protectant for cars. Some use long-chain fatty acids, that's equal to 4-12 drops of Armor-All per liter. One omits the Photo-Flo type chemicals and uses the 100% "natural and organic" "Murphey's Oil Soap" like you use on hardwood floors instead. The other stuff is fragerence and coloring. One brand uses butyl alcohol (smells like banana oil) and one brand uses amyl alcohol (sniff it, and you'll get an erection!). Because of patent and copyright issues I can't name the brands of the products I anylised, but your nose, and fingers and tongue can give you "possible suspects". The only item I know of that's more over-priced than record solutions is glass cleaner! I have NEVER bought any glass cleaner since I moved into my house 27 years ago next April. I "roll my own", after working a number of years as a janitor. Water (free) a little cheap sudsy ammonia (.79 1/2 gallon) a tiny little rubbing alcohol and green food coloring ( I like green better than blue) and it cleans better, goes 5-10 times further than what you buy. Oh, my sprayer is a thrown away glass cleaner bottle about 15 years old out of a neighbor's garbage can. Wipe the windows with old newspapers (free)
