Get the Pt off with molten lead? Cupel the lead and you're done. One knife at a time in a small long stainless container on a hot plate. or even a drop on a soldering iron could dissolve it? Not sure how long it takes to go in solution. I looked up dissolution rates of Pt in lead, but all articles talk about lead free solder, which dissolves pm's faster as i understood. don't know if you can cupel Sn.

Stainless steel can be pacified by what is referred to as "Reverse AR".
Same process as stainless steel watch bands.
