If your wall, outlet or appliance is stained with a blue goo or "Smurf Juice",
and it seems to be coming from the electrical cord... The cord is rotten. This
is a common problem with older wiring. There is liquid plastic added to the
pvc insulation to turn it from rigid pvc (pipe pvc) into flexible pvc for
wiring. If it's old or badly made it will rot and the liquid plastic oozes out
everywhere. This chemicaly reacts with the copper conductor and forms nasty
green plastic+copper goo. Since this is a cord that will be moved, definately
replace it before it rots away and falls off.
