Small brass pieces are cleaned in either of two solutions available from clockmaker's supplies: Ammoniated or Non-Ammoniated, bought usually as a concentrate diluted with water. There is some discussion and controversy about the effects of ammonia on brass, such as intergranular stress cracking.....but that only worries us clock guys. As for me, I clean all my brass first in the non-ammoniated cleaner, then wither polish with Nevr Dull or brasso, depends on the part. Check out www.slarose.com .
