Water content in whiskey is too high. Even cask strength whiskey rarely exceeds 60%, while rubbing spirit will be 80%-95% alcohol. Alcohol acts as a lipophile (fat-loving) solvent only when there isn’t too much water to emphasize its dipol nature. Permanent markers use lipophile solvents and don’t solve in water.
