None of the wiring is frayed. A few of the screws are rusted or corroded. It needs cleaned badly. It reeks of stale cigarette smoke. Should I clean what I can reach, or take it all apart and hope it works when I put it back together?
You could always just test it out on eggs that aren't high value...and see how it goes. I would probably just clean what I could reach, but I'm not handy and would be afraid I wouldn't be able to put it back together correctly, lol.
