If it's a BHW barrel, maybe not so much. Those polygonal barrels just don't retain much copper or powder residue. However, I have seen the tell-tale blue just from a bronze brush being attacked by the ammonia. That's why I try to stick to nylon brushes when I'm trying to eradicate CU. That way I don't get false positives from the tools.
ETA: If you do use bronze brushes with copper removers, I suggest rinsing the brush in hot water, afterward. This will neutralize the solution and help protect the bronze brush from degradation. (I had a 30 cal bronze brush that turned into a .243-ish brush because I had exposed it to some Tetra copper remover, and left it.)
