A Saniclean solution is acidic and, as such, will strip some copper from the surface of a copper item. Take a corroded penny and drop it into a solution of Saniclean or Star San for a few minutes and see what happens. However, folks who sell copper systems are known to reco aggressive caustics or acids to 'open' the surface to beverage in the fermentation, etc. In the case of a heat exchanger you're not worried about surface/fluid interface but damage to equipment. So, Saniclean will strip some copper and corrosion, which will prevent mineral buildup hampering heat transfer and it will not dissolve your equipment into vapors (poof!).
