So I recently purchased 2 corny kegs, they are decommissioned kegs from Canada, (one held 7-up the other club soda). They are a little different than my other corny in that the pressure relief valves on top flip up to release pressure instead of pulling up on a ring.
Anyway, these have been sitting in my closet for a couple of months and today I decided to clean and inspect them. I was able to vent the pressure fine, (they had quite a bit but I am at around 6,000 ft elevation).
The problem is that I cannot budge the lids. I even tried tapping the tops with the handle of a screwdriver, but no go. I know the pressure is released because nothing comes out of the poppet valves when I push the centers in and the top relief valve has vented totally. I am guessing that old soda syrup has cemented around the lid o-rig.
Any ideas? Thanks!
