A generally accepted recipe based on suggestions by Laura Dearborn and others is:
3 parts distilled water (triple distilled, de-ionized)
1 part Isopropyl alcohol, 70% commonly available but 91% lab grade preferred.
A few drops of photographic wetting agent – if possible Triton X-100, Triton X-110 or Triton X-115 or Monolan 2000, not Kodak Photoflo which is ‘reputed’ to leave a residue (though used by some). Recommended is 12 drops per gallon or 2-3 drops per litre, though some use up to 8 drops per litre. If you add too much, the fluid gets sudsy on the record.
Variants:
Replace the wetting agent with washing up liquid or windscreen wash fluid (reputedly pure) or industrial glass cleaner e.g Micro (a laboratory-glassware cleaner) or Liquinox
‘’Lately, I've been using straight windshield washer fluid. It's the only mixture I've tried that leaves no static film or visible residue on glass. It definitely cleans’’.
‘’The solution I used to use consists of a quart of distilled water, a pint of 99% isopropanol (from Safeway) and 3 drops of Dawn dishwashing detergent’’. .
‘’Photographic "wetting agent" is soap. I have cleaned and repaired Navy reconnaissance cameras with it. Ivory dishwashing detergent was the usual and natural choice for this as it is the mildest out there. A little Ivory and a lot of distilled H2O will do many good things for you. The Navy spent big bucks on this solution. Then a tech rep spilled the beans and we made our own’’
Use other alcohol types. This issue is controversial. Examples proposed include Denatured alcohol (90% ethyl, 9.5% methyl, .5% pyridine) BUT this is a carcinogen, and ethanol..
After washing the record with this cleaning fluid, rinse with pure distilled water to remove any residue.
