Any rules of thumb on how many CA finished pens you can make before cleaning excess finish from the bushings? Seems logical that this has been asked before, so sorry if this is a repeat.
You can soak them in acetone on a small glass/bottle. It is a good idea to string them in wire (preferably metallic) to make it easier to retrieve them.
How often depends on your style...like how much CA you leave on your bushing.
