A friend of mine gave me an old 20lb CO2 tank that has a tank date of 1979, so it is likely to have been filled years before that. It seems pretty full and I was thinking of using it. Any dangers of using it? I know CO2 doesn't go bad, but can the tank corrode causing impurities in the gas? I don't know where the tank came from, so perhaps there is risk of the unknown?
