A wire housing functions as a receptacle for connectors when they're mounted onto a PCB (printed circuit board). They keep the connectors organised and provide some protection.

Isopropyl alcohol is effective at removing corrosion but it's flammable so must be used with care. An abrasive PCB edge eraser, also known as a cleaning scrub block, is another option.
