Hi all,
I recently got a cyma pocket watch I got it to work but the case was encrusted in something that was really hard to get off.
I did eventually get it off but the case is still tarnished, I tryed a few methods but it didn't really work.
Would any of you guys know how to effectively polish a ss case?

Thanks
Francesco

I'd try Tarn X, slightly acidic but shouldn't harm stainless steel, It will "instantly" take the blue off of blued steel! .
Follow up with semichrome polish

Thanks Paul

I have used Hope's brass polish for years on all my watch cases. It has no ammonia or abrasives & will make the old look new.
