Biggerisland, welcome to the forum, and thanks for sharing this interesting information.
The magnet idea is impressive. I also like your salt paste idea. I've been wondering for awhile now about using salt glows to help Morgellons. We have a store called Mountain Body in our town that's a cosmetic deli. They have the most wonderful, fragrant salt glows.

I love the lavender/tangerine glow, and the grapefruit glow is awesome too.
