When I make copper sculptures I wire brush the end product to clean it up. I am now making some miniature copper sculptures and it is hard to get into the tight spots with a wire brush to clean the residue left from brazing. Is there a way that I can dip them into a liquid solution to get the brazing residue cleaned up and then wire brush the rest to clean it up? Would there be a simple solution of something like pool chemicals or house hold cleaners? I am not interested in getting into acids.

Some of our Enameled Rings, these are handformed, made from recycled copper wire.
