Cleaning bronze or brass artifact???

[CaribbeanDiver]

I know the rule in the coin world (no!) but what about artifacts. I have a badge/medal I expect to be from around mid 1700's (see my other post) it is definitely bronze or brass. Should I clean it or leave it as is? it is mostly clean from calcification, but it is black.

Thanks

Most of the junk I find I run through the dishwasher a few times. This removes alor of gunk.
