NOS Tube cleaning

As Bob linked to and this as well:

My personal favorite for two decades.

Albert, which eraser do you recommend from the link you posted?

I like this one:

The knob turns to dispense more brush as it wears down. Refills available in fine and coarse as needed, just drop in and reuse the metal holder.

Good posts, everyone!
Albert, what do you do for tube sockets?

Thanks,
Sam

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.
