Maybe it's just me, but I tend to use up about 2-3 lids and caps per 2oz bottle of CA be it thick or thin. I usually have 2-3 extra ones laying around that are caked with dried glue and no longer useable.

I learned at a fly in (from Gordo-Outlaw) that soaking the caps/lids in a jar of acetone removes all the glue. Just plain ole Acetone... it eats the glue but not the plastic. I came home, soaked a few for a couple of days and other than the exacto scratches from trying to clean them off previously, they look brand new! I know they aren't that expensive, but it's nice to be able to recycle them instead of tossing them after every build. Try it, it really works!

What I reall like is the cool residue left in the jar after the acetone has evaporated. But then, I guess I'm easily amused.

Yep, I do the same thing! It really works well. I always keep a few caps soaking in the jar so they are always ready for me. When one clogs, I just pull out a clean one and toss the clogged one back in the jar.

LoL,I was tickled to death to find out that something would even do that. I had considered soaking them in debonder, but that would be quite expensive. I had never heard of using acetone...

Another trick in the use of CA is to glue a 3"X3" piece of scrap plywood to the bottom of the bottle , this larger base stops it from tipping over.
