I just picked up a couple of razors off ebay. All of them have jimps of some size or another (some really fine, others quite large). All are caked with gunk. Any suggestions on how to clean these out and get some shine in there.

I was thinking of starting with the brass bristle brush attachment with my dremel.

It would be nice to have something to let the blades soak in to soften up the gunk for easier removal. Any suggestions on something like this would be helpful as well.
