All, I think the reason Tarn-X does not recommend it for brass, is that it does give off fumes/odor, that may possibly be toxic. So, having said that, I still use it and, of course, with proper ventilation and a thorough flushing with warm water, then cold. There's probably some kind of reaction going on there, (with brass), but I have not experienced any difficulty for aggaffes.
