Got a 50s era silversonic. The case is in great shape (not stinky !!) with one exception: some of the metal parts on one side are crusted over.

Anyone dealt with this before? Should I bother trying to clean it up (if so, how?) or just leave it as is?

It's all on one edge of the case - maybe at some point it was exposed to something on that side that corroded it.

Fine steel wool and a toothbrush, wipe off with a cotton ball soaked in rubbing alcohol, then clear nail polish when completely dry.

Parts are brass plated steel.

Rust is on the steel, green corrosion is on the brass plating.

Both oxides will dissolve with this home-made remover:

1 Tbsp salt dissolved in 1 cup of warm white vinegar; enough flour to make it paint consistency.

Mask off all the corroded parts, paint the remover on them, and let them sit overnight.

The residue will clean off with a toothbrush sized wire brush (Home Depot).

Nail polish (lacquer) comes in all colors these days, including brass.
