I want to use vodka to clean my wine cellar, does it leave lingering odors behind and affect the taste and aroma of my wines.
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
I suppose you could use vodka safely but not on the labels, but that is not really needed. A soft dry cloth to clean off the wine bottles will work just fine.
As far as mold and mildew, if you have an issue, you need to remediate that so the humidity isn’t excessive.
I did find a somewhat interesting post by Martha Stewart on her wine cellar being cleaned.
