Eran I couldn't access the thread so I wanted to let you know that you can dry out those beads with a hair dryer until they turn opaque again. That is what I have done. I had my beads turn brown also and thought they were not working and decided to redo them so I soaked them in distilled water but they are still brownish and then dried them with a hair dryer. Needless to say they still work and are still working to this day.
