[QUOTE="MagnumManiac, post: 2131444, member: 10755"] Depends what it is. If it’s Verdi Gris (green corrosion) this is brass oxides forming, this can be just discolouration, but if there are pits and a white substance too, then it goes in the scrap bin. If it’s black or brown spots, that is contaminant corrosion, like what happens if brass is left in a damp leather pouch or belt. This is harder to remove but poses no problem with integrity of the brass. This is caused by the tanning salts/chemicals in the leather. For stubborn stains, 0000 steel wool works fast to remove them. Water marks are also easy to remove with steel wool. Cheers. [/QUOTE]
