[TheForge] Copper vs. coronavirus

[Ron Childers]

I have made copper bracelets for people who say they worked really will for arthritis but there is a green stain around the wrist. Would they help combat the virus? My wife wore gold rings on every finger and said it helped her arthritis.

I agree with the ordinary precautions.
I think I read somewhere that silver is not as effective as copper as an antimicrobial, but perhaps that's because it's slower to tarnish?
(Chemist, here.)
Copper is unsafe as a cooking vessel (as opposed to just for fetching
water) *unless* the tarnish is first removed.  The tarnish is soluble in even very dilute acid, and copper (although a necessary nutrient in *trace*
amounts) is toxic.  Bright copper does not release atoms, but tarnish is copper oxides and does.
So, that makes me wonder whether the toxicity of copper ions (which I'm now speculating relates to the relatively short survival time of bacteria and viruses on copper surfaces -- which usually have at least some tarnish or
verdigris) might be exploited more actively:  Suppose we made a hand sanitizer that contained slightly more than trace amounts of copper ions -- enough to kill germs?  What if we treated paper face masks with copper ions
-- which would easily be done?
There's already a provisional patent on a mask with sodium chloride (table
salt) crystals which are said to destroy the virus in minutes, mechanically.  That, of course, is a better idea because salt isn't toxic.
But it doesn't hurt to pursue multiple avenues.
If things get worse, I might try out my ideas on myself, but I have no way of testing efficacy or safety, so wouldn't do more than that.  In the meantime, I'm washing my hands frequently, washing my face at least 2x per day, washing down surfaces, knobs and other hand-holds daily, taking my temperature daily or more, and of course, socially isolating.
I think the worst of this isolation psychologically is that it brings out my potential hypochondria, which, fortunately, is minimal, "Gee is that pain a lung infection?" (No, it's just a muscle ache from sleeping in a bad
position.)
FWIW, I'm using some of my time to start up my garden.  A "victory garden"
might be very useful this coming season.  I harvested lots of beans, carrots, Swiss chard, and tomatoes last season, and a smattering of other things.  I'm starting earlier this year with peas and spinach, and will be putting more things in (lettuce, Swiss chard, Brassicas, etc., soon, followed by beans, carrots, and maybe even a Ruth Stout potato garden.
