Restore Bolts?

[Bru]

Hi Everyone,
I'm scratching my head trying to figure out what the best way to clean up all the bolts we pull off the car so we can use them again.
I've done some searching on the site but don't see much.

Is there a tried and true way everyone uses?
It seems like it could be a time consuming task.

Any help or suggestions would be appreciated.

We're looking at the Chassis bolts at this time for a 1970 Cutlass Supreme.

Thanks in advance.

Kevin
