is it safe to clean records with isopropanol ?

If you regularly imbibe your alcohol-based record cleaner, you will not live to own your LPs as long as Mosin, or I. Alcohols with longer aliphatic side chains, like isopropanol (vs ethanol or methanol), will be more or less hydrophobic and have different properties as a solvent therefore, I think. Isopropanol, for example, may be better at removing fatty deposits from finger-prints, compared to Grey Goose.

Actually, the long-chain soaps and detergents that are also surfactants would do a better job of removing the longer chain oil-based contaminants. Further, those same surfactants are more highly soluble and should rinse at least as well if not better than alcohol. Mechanics don't use alcohol to remove oil from their hands after working, they use soap.

Besides, why waste good ethanol-based fluids on records. Better to consume while playing rather than pitch down the drain after using. Wait.... That happens in either case.

I use Vodka. My favorite Brand for cleaning is Smirnoff.

I used to use vodka for cleaning, but I always woke up in a fog. What went into my mouth as a clear liquid came out of my eyes with a distinctive red tint.

NO DUDE!!
