Cole, this is very unusual for you to receive this amount of unusable brass in an order. If it is the case, submit photos of this brass to us and we’ll take care of you. If you are referring to the black staining on some brass, it can be removed with hot water and lemishine, available at most grocery stores. Lemishine is a food grade citric acid. Or, if you have the ability to wet tumble these with some stainless steel media, the brass will look brand new upon completion.
