Shelf-life of super glue. This is one of my personal battles at my hobby table. After your superglue dispenser gets a build up of glue on the inside near the tip, and you start to get in trouble. When you use it, if you wait too long, 10 mins sometimes, the glue will not have fallen back into the bottle, but will set in the tip. Since we know that the glue will be harder than the plastic dispenser, we're in trouble. Eventually, you'll find yourself cutting that tip back constantly just to get some glue out.
Here's what I do, though the effort is still unsatisfactory. Everytime I use the glue, I repeatedly jam a thin peice of metal wire into the dispenser until I force the glue back down into the bottle. Glue builds up on the wire, of course, so I wipe if off. When it sets on the wire, I scrape it off with the back of a blade.
If there are better ways to keep your superglue useable, I really, really want to hear them. Please!
