The GFO you use is "pure" (as far as I know) and doesn't have any other form of "leaching" material. These clams, on the other hand, are made of other materials and with rusting, there's always a possibility that the stainless steel coating will turn into ferric oxide and thus exposing what's beneath it. Thus its not only ferric oxide. Why take the risk?
