[Harp-L] Sterilizing Harmonicas with Ozone

People who would never thing of borrowing a used toothbrush will check 
out someone else's harmonica. Needless to say, this is not an ideal time 
to be playing other people's wind or reed instruments without 
sterilizing them first.

The Wuhan coronavirus (aka CCPneumonia) can apparently survive for days 
on hard surfaces. Though you may be tempted to use an ultrasonic 
cleaner, although they do a very good job at mechanically cleaning the 
harmonica, ultrasonic cleaners aren't very effective when it comes to 
killing microbes (though I'm sure that many are washed off in the 
process). While I doubt any of the consumer ozone sanitizers have been 
scientifically tested, ozone will indeed kill viruses and you can get a 
battery powered ozone sanitizer for $50 or less that will fit 10 or 12 
diatonics at one time.

This is the one I use and it's just $30 on eBay. Less than the cost of a 
pro harp. 

You can also use an ozone sanitizer to sterilize your paper money and 
credit/debit cards, likely the most contaminated things you carry.

PS. If you have a 3D printer, you can print N95 masks:

also have the CAD files if you need to resize.
