What would cause all of the wall outlets in one room of your house to have slimy green discharge coming from where electrical plugs enter the outlets and how can you remedy it?

Answer 1

This is a form of corrosion sometimes found on wiring or in the outlets. You need to have a licensed electrician replace the receptacles and to inspect the wiring to see if it may also need to be replaced. Either turn off the breaker or pull the fuse that supplies power to this room until it is repaired.

Sounds like mold new one on me.

This suggests to me that the wall holding the outlets is damp - from rising damp, roof or window-frame leaks for example.

Always be sure to switch off the breakers at the main panel before you attempt to do any work on any mains power circuit.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

Answer 2

Slimy green discharge is a sign of copper corrosion, likely caused by moisture seeping into the electrical system. To remedy this, first, turn off the power to the affected room at the breaker box. Then, remove the outlet cover and check for signs of water damage or leaks. If you find any, repair the leak and replace the affected outlet. It's recommended to have a professional electrician assess the situation to ensure it is fixed properly and safely.
