Methanol, ethanol and 2-propanol (aka isopropyl alcohol) are all fantastic cleaning chemicals with extraordinarily similar properties.
The longer carbon chain, yet still polar propanol makes it slightly better for removing grease type substances. It is also slightly less toxic than methanol if i remember correctly.
Ethanol should not bother your components although it is best consumed orally rather than poured onto cleaning rags for the wasting.
Save the Russian Vodka for the $20 speaker set with the shrilly high end. It might help tone down the high end a bit with a slightly laid back slur. The more you apply, the more laid back it gets!
