FSS-KLOOT,
Probably nothing wrong with them just that in spite of the name, they are not a germacide. The company advertizes them as cleaner and deodereizor.
CELESTE INDUSTRIES - Sani-ComŽ Sanitizing Wipe
I received a couple of good tips from responses to this question, but I was hoping that some airline or military outfit might be using an actual germacide on their O2 masks and microphones.
I think that most health organizations would disagree that there is no risk of trasmiting a cold or flu via masks and mikes.
Thanks to every one for the information.
