I don’t know what you mean… water and electricity are like best friends 
I was thinking that it could be put into a separate chamber and have the “mist / steam” ported through small holes right out of the end of the emitter. right at the point where the blade is inserted so it wouldn’t come into contact with anything electronic.
the chamber could contain a damp sponge for the mister with the electronic control module with the rest of the electronics.
just thought it might make it look more realistic for ignitions or post off retractions and possibly end melts…?
