Pro tip: I called contact cleaner a waste of money until a King Air gremlin humbled me
A guy at the shop in Wichita kept saying half our intermittent squawks were just dirty edge connectors and I figured he was lazy. Then I burned 6 hours on a King Air 200 chasing a flap position fault that only showed up when the cabin got cold, and every pin on the connector passed a wiggle test. Finally pulled the connector, hit it with DeoxIT D5, cycled it maybe 10 times, and the fault never came back through 3 more flights that day. Now I clean the pins before I swap a box, and it has saved me two more sign-offs. What's your go-to for connectors you can't reach without pulling half the panel?

Learned the same lesson with my lawn mower, spent an hour messing with the carb before realizing the spark plug cap just had corrosion. Funny how the cheap fix is always the last thing we try.
