Anyone have a decent cleaner to use on really grungy 80 year old connectors? I've got good cleaners for the pins that I use, that comes from Jax Chemical, but need to clean all the grime from the bodies. I've got a Silver Dragon steam generator for small areas, but I'd like to be able to toss a couple of bagged bodies into the ultrasonic and let them vibrate for a while.
