DIY record cleaning solution recipe needed


Do you make your own cleaning solution? Would denatured water and isopropanol work? Is that bad for vinyl? I'm using a cheapo Discwasher brush with D4 fluid. I want to make my own fluid! Thanks for any info.

Here's a link from Soundstage with a recipe:

I know most of the major mags had an article about different recipe solutions. You might check the archives at Stereophile, TAS, Listener, etc.
1 part isopropyl alcohol to 7 parts distilled water (volume based). 1 drop Dawn detergent per 1 liter of the above. Actually, I do one drop Dawn per 200 mls total volume. I use this as the preliminary wash followed by steam cleaning and 2 steps of Audio Intelligent (enzyme and neutralizer) followed by a final steam cleaning. I use a record cleaning machine in between all steps (e.g., in between AI enzyme and AI rinse.
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.
