OK guys, thanks. I do not have an ultrasonic cleaner, but I think I could find one. So far all I have done is to brush off surface dust using a soft camel hair brush and added some lubrication before I turned the tuning capacitor to facilitate additional cleaning. None of the vanes appear to be touching - movement is nice and smooth. I removed the capacitor and its mounting bracket plus dial-cord pulley from the chassis, so at least I will be able to get to all sides of it.

I think it best to avoid Formula 409 or anything with ammonia or chlorine. I know that chlorine will corrode aluminum over time.
