Is there an accepted, "best" way to clean up lightly rusted laminations and covers on power and output transformers? I've been lucky enough to win a Dynaco ST-35 on eBay and want to restore/rehab it when it arrives. The pictures show some rust on the transformers, which I suspect is superficial and not fatal. I thought I'd ask here first, rather than damage transformers or allow the rust to continue to spread.
Thanks in advance.
