Sam,
I've used small brushes designed to fit tube sockets, I don't remember now where I got them.
End results and time required did not equal benefit received. Then again, NOS tubes, many going back to 1940s and 1950s are far more in need of cleaning than (relatively) new high end equipment sockets.
