Cleaning/rehabbing/prettying-up tube power and output transformers.

Greetings my fellow HollowState Devotees!

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.

Sponge sanding blocks, get the medium grit. Sand lightly untill the rust is gone. Use a paint brush (dry) and brush all the dust out of the grooves and nooks. Mask the wiring with Green or Blue painters tape because it removes very easy. Rustoleum or Krylon have a semi-flat black paint that works awesome. I few light coats just not one thick heavy coat. Allow the transformers to dry for 24 hours. You should be looking good
