What does a wire housing do?
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.
How do I clean a PCB connector?
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.
