As PE implied in his response, you're saying that TEA and salicylic acid have a super-additive-like effect in chelating iron?

I did a google search for sequestering iron, and it appears that there are few methods of dealing with it. EDTA (which I think is in XTOL) and sodium tripolyphosphate (STP, not TSP) are a couple of choices.
