Cabin winterization

[blackcatsamurai]

Hi all. Long time lurker, first time poster. My wife and I recently purchased property on Bear Island ... we love it!! I am admittedly not the best of handymen, but I can hold my own. That said, I pose my question ...

I am heading up soon to close the camp. Many recommend using anti-freeze in the drains to prevent ice once we have cleared the system. I know there are some options which have minimal impact on septic and such but am wondering ... has anyone used vodka instead? This seems like a relatively cheap alternative, and one that does not use anti-freeze and all the fun chemicals it contains. My googling has revealed a little info on this but am curious if any other cabin closers out there have used and found success this way.

Thanks in advance
