FWIW. Vinegar with some salt is the usual mix, soak as long as needed and periodically agitate with a soft brush, then apply water mixed with some baking soda to neutralize the acid. Thoroughly dry and apply DeOxit.

I don’t think I would fully submerge all of it unless that seems obviously necessary.

The newer panels (1985 and on) are relatively easy to clean in the manner Dr Bob proposed because because all the items you want to clean are in approx. the same plane*. On the older panels there are 3 stepped planes - The fuse-holders are highest the male pin CE panel plug connectors are next and the relay terminals are the lowest. The relay terminals are sandwiched between the fuses & CE connectors so to fully submerge the relay socket terminals - you will have the fuse wire ends under your vinegar solution, and the CE panel male pins almost totally submerged to the wires

So its a compromise for the early ones. Stripping all the wires is a very big challenge (putting them back correctly more-so)

*the new panel fuse terminals are indeed slightly higher mounted - but their terminals are also physically longer

Then there is this thread that talks about using CLR... seemed to work.

What about Ultrasonic Circuit Board cleaning solutions, as used for cleaning Cell Phone's and other Electronic circuit boards?
Thoughts?

I remember "cleaning" circuit boards with 95% isopropyl, but that was more for removing flux deposits. Final rinse is DI water. Solvent cleaners like that don't do anything for corrosion on the connectors, which I think is the theme of the discussion. Vinegar as originally proposed is about the perfect option really. Very mild acid, washes out easily and pretty much self-neutralizes as it evaporates.

There are cream-of-tartar and salt home remedies for copper cleaning that I'm not sure I'd be trying on the wires, especially since white vinegar is only a few cents more than bottle spring water these days.
