Vinyl Cleaning

I make my own cleaning solution. Get a 1 gallon jug of distilled water, and drain off 1 pint of the water. Then add 1 pint of 99.9% pure isopropyl alcohol to the distilled water, plus 1/4 teaspoon of a good surfactant (a high quality liquid detergent will work, but I usually buy a chemical surfactant from a chemical supply house). Shake the gallon jug of solution to distribute the surfactant. You can store the solution in the jug or a glass container (such as several quart Mason jars).

I use this solution with my Nitty Gritty cleaning machine. Apply a fairly liberal amount of the liquid to the surface of the LP, work it around the surface of the record with a gentle brush, or an applicator such as the one that comes with LAST record preservative. Then vacuum off the solution.

I've been using this solution and method for more than 20 years and have been very pleased with the results.

There is a discussion on this topic which is entitled "Best cleaning fluid procedures with the VPI 16.5." Some don't like any alcohol, although using 5% isopropyl alcohol and 95% distilled water along with the dab of soap (surfactant)will do the trick. Too much soap will cause it to foam and leave a residue. SDCambell may be recommending far more alcohol (12%!!)than is useful and could harm the vinyl if left on for any length of time. Also, there is no 99.9% pure alcohol as chemically, it's a virtual impossibility. Typically, you'll find 60% and 90% at the drug store. Go for the 90%.

(In case you are wondering, the balance of the alcohol in the 60% or 90% solutions is pure water. As you may recall from chem class, alcohols and most acids love to absorb water, making it reasonably impossible to get more than about 95% to 98% pure unless you want to spend the national budget.)

Hey, SD!

I haven't noticed any ill effects from alcohol either, but some folks are (rightfully) leery of putting ANY alcohol in the mix. Part of the reason I try to use a minimal amount is that, after cleaning several albums, the alcohol odor starts to get to me. If it were only Jack Daniels instead of isopropyl.....

Perhaps the "99.9% pure" refers not to the percentage of alcohol, but to the overall purity of the solution?

Alcohol doesn't damage vinyl by itself. However, sometimes plasticizors are included to the vinyl to make the vinyl composition more flexible and workable. Adding plasticizors make the stamping process easier, and made shipment damage (loss of profit) less of an issue, since the record was more flexible. Most plasticizors are composed of di-basic fatty acids, and are alcohol soluable. (they will disolve in Iso-Propyl Alcohol,(IPA)

I have tested many samples of LP records to find which labels did and which didn't use plasticizors in their vinyl, and found that non were consistant. I even went as far as to test vinyl from different plants, I.E; Mercury and RCA had various plants. There was also an inconsistency in the amount of plasicisor used. Maybe different compositions were used by different engineers, or maybe it wasn't an issue.

At what rate does the plasticizor disolve? Once again, different compositions equal different rates. Could we clean LP's for 50 years with straight IPA? Are we all too anal about the whole cleaning process? Maybe. While there is no concrete information as to whether or not IPA based solutions will damage your LP's or not, I'll continue using alcohol free.
