Tetenal working solutions i have kept at just below room temperature in a cupboard under the kitchen sink, in airtight collapsable bottles tightly capped. Longest i have kept a good working solution is 3 months, i usually use them to capacity well before then.
I'm going to try what someone else suggested some kind of gas from freestyle, but where do you just buy butane? like, from a bernzomatic torch gun from home depot?
