this is the back place of the attachment for the center section of a 70 steering wheel. you can see that the plate and bolt are pretty rusty. the flip side is in pretty good shape, and i think just a general cleaning will be fine.

how do i clean the rust off of the bolt and plate, and then what about the final finish? what should the finish be, and can i do something close myself instead of taking it someplace to have it plated?

i'm not necessarily looking for a concours restoration here, but would like to be close to original.
