How do you clean tube pins?


I'm sure there must be some discussion on how to clean tube pins (both power and small input tubes), but I haven't been able to find much on the subject. Specifically:

1) As tube pins are so close to each other, what tool do you use to clean the pin?
2) What solvents do you use?
3) How often should you clean tube pins?
4) Any other advise / suggestions you'd like to share.

In advance, thanks for any suggestions you may offer.

Take a normal pencil. Drill a small hole in the end centered. Fit tube pin into drilled hole and rotate. If you need to get SST off use an emory board.
I've been using contact cleaners of varying discriptions on tube pins for 30 some years. All it takes is reading the instructions and a modicum of common sense to use them successfully, and without any sort of damage.
I've had good luck cleaning steel tube pins on small signal tubes by cutting small strips of 1000-1200 grit wet/dry sandpaper and wrapping that around the pins and oscillating the paper over the pins. Really gets into all the hard to reach areas that are harder for me to reach with the steel wool method.
Bend a pipe cleaner 180* dip it in Kontak cleaner and you will be able to clean all sides of a tube pin.
