[Amps] silicone remover?

[gdaught6@stanford.edu]

Hi all,

I'm converting an Eimac SK1400 to ground the screen grid.  I've 
removed the insulating washers, but I've got a thin film of silicone 
rubber on the finger stock and the mounting rings.  

I've tried pencil erasers, scotchbrite, and even fine steel wool.  Is 
there a chemical (organic solvent, maybe?) that will remove the film 
without removing the silver plating?

Of course I could just do my best with gentle mechanical efforts, and 
put it all back together.  The silicone won't show, and the contact 
would probably be fine.  I'd just like to get the maximum area 
(lowest inductance) connection that I can.

Any suggestions?
