Dekay, I wouldn't worry about the iso-propanol extracting the plasiciser from the vinyl, not methanol nor ethanol. Just stay clear of denatured ethanol, because the denaturant is sometimes benzene, which would be harmful. The other alcohols do not contain denaturant, as they are not drinkable anyway, which is why the ethanol is denatured, to discourage people from drinking it.
As for mixing armagnac with water (any water), I frown upon that habit, just as adding water to good scotch!
