How long is CO2 in a 5 lb tank good for?
I have a CO2 tank that I've had since the mid 90s (94-95). I haven't used it since then. It still has 800+ psi inside and other than some dust on the exterior of the tank and regulator, it seems to be OK.
I'm getting back into kegging and would like to use the CO2 in the tank. Is it still good? Does CO2 go bad after some time? If so, what happens to it? Should I purge and refill the tank?
