I suspect anything you sprayed on it would make it stink or get sticky after a while. Sounds like you need a Mr. Wizard type to tell you what the electrochemical process is that you're experiencing.

The Sharper Image has ion air filters that are supposed to attract dust and hair, and you stove seems to be doing that same thing. You're dealing with an electrical charge. You might look into either getting one of those air cleaners to draw dust and hair away from the stove, or research how they work and see if you can come up with any ideas for counter measures.
