Good question. You know what ospho is, yes? OrthophOSPHOric acid...I know the claim is that it goes inert in a while, but I don't know what they mean by a "while". I'll be curious to hear what others think. I believe you'd be safer with oxy-acetylene (fewer fumes) but I realize I'm one of a dying few still using that system regularly.
