I love these building pins but notice that they often get rusty, and once they get a little bit of rust on their shafts they get very hard to push into the balsa.
I'm sort of a "waste not, need not" guy, so I don't want to throw them out (and they are not that inexpensive.)
I sand the really bad ones to clean the rust off, but there must be an easier way of getting rid of the rust. How do you guys handle this issue?
