Care and feeding of a Hip Flask

[uberjoe]

My wife just bought me a stainless steel hip flask, and I was looking for some tips on its care.

Do I need to wash it out or is rinsing fine?

Also how long is it safe to store liquor in it? It's stainless steel so I assume it wont corrode. Is there a type of liquor that will keep best?

Thanks in advance!

I was always told that a simple rinse was fine between uses, and never keep liquor in it for more than three days.

3 days is the max they say to leave alcohol in a flask, I'm not sure why though

Most everything I could find said not to store more than 3 days, but I don't think thats true. Aren't most spirits fermented in stainless steel casks? I can see not storing in pewter or some other reactive vessle, but stainless steel?

I guess I was hoping a chemist frequented these boards :(

I only rinse mine between uses but I mainly keep vodka in mine (for emergencies...). If you were walking around with a pocket full of creme demonth it might be a different story. And you would probably deserve everything you get.

For some reason long term storage has never been a problem.

No creme de menthe for me thanks. Gin or Whiskey only.
