Brasso or other metal polish should work. The Brass Builders Yahoo list is talking about dips to clean brass at the moment, might be worth checking out.

Now that I have the facility to work on it the brass is so oxidized that I can't get the solder to stick, even with acid flux. I know bead blasting would help but right now my spray booth and all my spray tools are in storage and I have no place to set them up. Any suggestions on how to clean the brass so the solder will stick without damaging the small parts? thanks Carey
