Earlier I unplugged my outdoor camara and noticed a bunch of rust on both pins of the plug.. The rust is mainly at the base of the pins closest to the plug itself.. I assume rainwater seeped in over the years which caused the corrosion.. How should i go about cleaning it off? Is it dangerous if i leave it how it is? I know corrosion increases electrical resistance but since theres very little amperage supplying the camara should it be a problem?
