I would make a special mention for binders and chelators. If you're mobilising metals, or other crap, I think it makes sense to have stuff on hand in the a.m. to mop,bind that stuff up. People use various things ...pectasol with alginate, charcoal, EDTA, OSR1, microsilica (biopure),etc. I am still working on finding good safe chelators. Ideas welcome.
