Final Results
After one week of soaking in the Iron Out I was not
fully satisfied and put the kyanite in the CLR for a few more days. I think
this is as good as it is going to get. Of interesting note, the Iron Out developed
an emulsified look to it with islands of greasy looking material floating
on the top as a scum. The CLR remained clear throughout but darkened considerably
over time to a tea color as it leached the specimen.
The residual “stain” is actually in the mineral. All the surface
iron seems to have been removed leaving clean quartz, kyanite and an iron
mineral, perhaps hematite or magnetite micro crystals.

The two links below tell about the Willis Mountain
Mine where this sample
was collected and from a field trip that show the geology of the site and
some pictures from the mine.
I found this sheet between two slabs that I separated on the top of the mountain.
