is it safe to clean records with isopropanol ?

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!!

Mechans wonders why isopropanol is regularly used in preference to ethanol. The principal reason is that ethanol has a higher vapour pressure (and lower boiling point) than isopropanol so it will evaporate faster from the record surface, perhaps leaving behind all of the gunk it originally dissolved.
