Thanks, yes, I'm wondering if this isn't so bad. I see a lot of razors with some gold plating and some tarnished brass peeking out. Seems like it wouldn't look as bad having dull yellow or dull red peeking out instead of green-gray or black.Acid will clean brass but won't polish it. It will be dull yellow or dull red, depending on the time of exposure.
While acid won't affect gold, it will eat away the brass beneath, so the gold will still be lost, except for heavy gold plating.
