Green gunge on wiring Ask questions and find answers to many subjects relating to electrics and electrical work

[BT]

Have just moved to a new house and discover that there is a green material staining some of the sockets. Removing them shows green gunge on some wires/terminals. Wiring is probably 30-40 years old. What is the cause of this, I have never seen it before, even in older properties. Does this mean I need to rewire?
