Am I on glue or did I hear you say a silver nasal drip will 'burn'? Shouldn't...Mine doesn't. How about going back to the drawing board and getting pure 9999 silver electrodes like those from C.C. Silver & Gold in Phoenix?

I would use a plastic spray bottle to shoot silver into the nose. I would not ever use silver in any SONIC cold steam device and would be wary of it's use in electric hot humidifiers because of potential interaction with metal electrodes.
