I have an external 3-pin socket. Its proving very hard to withdraw any 3-pin plug I use in the socket. Its so sticky I now risk pulling the socket off the wall. Is there any suitable / safe lubricant I can apply to the socket to remove the problem. Pls advise on this or any alternative solution. Thanks.
What do you mean by external socket? is this located outside?
I personally would advice you to replace the socket-outlet but firstly check it is not the plug that is not causing the problem with bent pins!
