>     It struck me that many people, myself included, say, "Be careful
>     with that" or even "Don't even go there" with regard to HF 

    I perfected a non-acid (ph 6.8) substitute for HF--Multi-Etch--which
    is sold through Reactive Metals Studio. I don't know if it would
    work for platinum divesting but I do use it to clean platinum prior
    to solder/welding. Of course, it also works for titanium. And it's
    ideal for bringing up detail on mokume and meteorites, etc., etc.
