DIY record cleaning solution recipe needed

To make 500ml = 2/3 distilled water 1/3 reagent grade isopropyl alcohol and 2 drops of Jetdry.

High purity isoprpopyl alcohol is really an ineffective or unnecessary cleaning agent with about 99% of dirty records and I have easy access to it along with ultrapure water with my wife being a researcher.

The best commercial record cleaning solutions have absolutely no alcohol in them and are followed by a high purity water rinse (usually a couple of rinses with high purity water as this is just as much of a "cleaning" step as the initial cleaning solution).

Alcohol is really only necessary and beneficial if you are dealing with a particularly "greasy" record to cut the grease and it doesn't happen very often.

DIY cleaning solutions are not worth the time or money invested. Buy a high quality commercial first stage cleaner (the AIVS 15 is very good, combining both surfactant/detergent and enzyme stages) and follow it with a high purity water rinse (the high purity waters available from the scientific supply houses are excellent and 1/8 the price of ultrapure from the record cleaner companies) and you will be set.

Notwithstanding the cleaning solution, the success of a well cleaned record lies in the scrubbing and a final rinse.

All cleaners do is emulsify dirt, so the rinse is the key, right? Please correct me if that is mistaken. Commercial products are so concentrated, it's almost hard to use up a bottle; at $35 (or whatever), every year or three, why bother with a likely inferior diy cleaner?
