It seems like every time I open a tube of super/Krazy/cyanoacrylate glue, I get one use out of it, and the next time I go to use it months later, the nozzle is clogged with dry glue (or worse, the entire tube has hardened. I put it back into its sealed canister, but it doesn't seem to matter.
What's the best way to store super glue to increase its longevity in the tube? Does it matter if I store the tube nozzle down, nozzle up, or nozzle sideways? Should I let it sit with the pin in or not? (I assume not, or at least not all the way in; otherwise if the glue dries up around the pin, the pin won't be long enough to puncture the dried glue around it.) Should I glue something to the tip of the tube to try to seal it?
