I don't think the bleach would destroy the chemistry of fluorite, but it
would be hard to rinse all the bleach out of the fluorite. Why don't you
try a day's cooking in a crock pot? After cooling and drying, the fluorite
should be ready to go. Since I use the local soil, I never had to worry
about saving it if I had to sterilize my gravel.
