How can baking the FINA kill the FINA? If it bonds to the BA, and the BA's boiling point is 400 degrees, then baking it at 250 degrees can't kill the Fina! Besides, all the kits tell you that you can boil water and place the solution in it to dissolve the pellets...
If you worried about killing the Fina, then bake your gear at 175 degrees for four hours. That should kill bacteria/viruses and not KILL the FINA...
