Of the various experiences with this, only once was it caused by dog's habit of peeing on wall in living room

If the wires ever got really hot. Some times they will appear corrosive.

My memory was of cats. Nothing like congealed cat urine on the devices to make you rethink your choice of profession.

I once had a troubleshoot for a short on a circuit. This was in an older house that had originally been wired with a mix of rigid black conduit and BX cable. I used a high-wattage bulb in series with the breaker to keep the circuit on, and ended up separating wires leaving a ceiling box in the basement to narrow it down.
The problem was an added receptacle in a Wiremold box behind the front door that was completely cat-urine soaked and had visible orange arcing inside the receptacle itself. New box, receptacle, and plate took care of the problem. I don't know what long-term solution the owner used to keep it from happening again.
I work in the summer in a camp that has a abt 35 trailers and come across several outlets a year with corroded wire. The wire is usually fabric clad in plastic boxes with green and/or white corrosion (these trailers are unheated during the winter)
Somebody told me that improper torqueing can cause corrosion???

Improper torque does not directly cause the corrosion. It increases the chance of overheating at that connection. My WAG would be the gasses from the burning or hot materials would be the corrosive cause.

Going by post #10. You are stating that the receptacles are in trailers with no climate control.
FWIW.
Without seeing it myself I would guess moisture.
