Thread: Cleaning without Disassembling

I just picked up a few old razors at an antique store in town. They're in decent shape overall.

But they have some rust around the pinned part of the blade. Not sure what the actual term is.

Is there any effective way to clean it without taking them apart? I'm just trying to avoid any more work that I have to do because they're in pretty good shape with the exception of the black one. It could use a new set of scales and a wedge.

and what's the best way to clean the ribbed part? Haven't found any good ways to get it yet.

The engravings from top to bottom are
