Too right! WD40 contains oils that dry to a resin, which is exactly what you don't want in anything electrical. The best treatment is ACF50, which kills corrosion, and lubricates but does not conduct electricity. Dielectric is the term. It creeps extremely well too, so gets to all parts. Only downside is it will creep out of connectors and collect dust, but better a bit of muck on the outside and pristine internals than the other way around!
