PSA: cleaned 30 years of grime off a Beechcraft panel connector and my squawk list dropped from 4 items to zero
Spent about 2 hours last Tuesday with contact cleaner and a soft brush on a 1996 Baron's autopilot disconnect plug, and the intermittent pitch trim fault just vanished. Funny how a $12 can of cleaner beats a $900 LRU swap. Anyone else got a go-to cleaning routine for old cannon plugs?
