I think I'll put mine in the fridge. Also, I don't know if it would help, but you can add some amount of isopropyl alcohol to VPI fluid. Perhaps it would serve as a preservative. You might want to ask Harry Weisfeld.
I have used one other fluid, but I find that the VPI fluid seems to work best on my machine (a VPI 16).
