I was wondering why those face shields can't be sanitized in a chlorine or quaternary solution. Same for goggles & other eye protection. It would also seem that cloth gowns - if they had them - could be sanitized and reused. Yes, throw-away is easier, but requires huge volumes in these circumstances.

It will be interesting if there is a way to sanitize disposable respirator masks, but we may never know. The risks are probably high enough that the manufacturers won't publish such a procedure when times are better.
