Say, per acetic acid--

Plastic?  Glass?  fridge?  Stopper?  Cork?

Store it in HDPE or glass in a dark, cool place (ideally a fridge). Make sure to have it loosely capped so pressure can vent as the peracetic very gradually breaks down into acetic acid and oxygen..

It seems to store well for a couple months in a fridge with no noticeable loss of strength. I wouldn't make so much as to have to store it more than 6 months.
