Can I use vodka to clean my wine cellar?
I've drunk some cheap vodka in my time ($US3 per liter was the cheapest) but I still wouldn't use it for cleaning unless that was the only option I had.  Vodka is not pure alcohol so it will leave varying degrees of residue do to flavonoids etc 

If I was going to use an alcohol based product for cleaning I would tend towards a Rubbing Alcohol that, while still not 100% pure alcohol, minimizes the amount of other ingredients and carries no perfume oils etc
