The wiring terminals behind my electrical circuit breaker panel have developed a green corrosion. I have brushed and cleaned the terminals off with a stiff nylon brush. And I have sprayed WD40 on it. The WD40 seems to keep it away for about a month and then it comes back. Does anyone have any ideas why this is happening and does anyone have a more permanent solution?
