Decades ago I was discussing this topic with an audiophile record store owner near Ohio State. He had a chemist friend who came up with the following formula:
1 gal of distilled water
90 ml of isopropyl alcohol
1 tsp of Alconox (a surfactant frequently used for cleaning labware; Photoflo should also work)
If you use Alconox, slowly add water to it and stir to get it to dissolve without clumps.
He claimed that the chemists tested the records after cleaning and that there was no residue. As I recall, the alcohol was sufficiently diluted to not worry about any potential damage to the vinyl.
