Its a smart idea, nothing in there about virus though.

Steam is anti-viral, IIRC.  I mostly just posted that to provide confidence in DIY procedures. Too many people think something has to be "medical-grade commercially-produced" to be effective.

Can you not just put it in an oven?

For the virus I believe its just a matter of breaking down the fat, hence soap works.

And Alcohol if strong enough.  Heat will do it.  Is it 60 degrees RC?  I dont think its know yet, but there is some guidance on time and temp, but I cannot seem to lay my hands on it.

With germs think about a buffet steam table.  If I put out a hot dish heated up in the kitchen, on a steam table, the table will hold the food at a redusced temperature for a long time for safe serving.  Think canned corned beef hash - it's already cooked before canning, but you still have to heat it to a proper temp before it goes out on the steam table for serving.

If you put cold canned corned beef hash (unheated in the kitchen) on a steam table you have created an incubator for germs. 

I have a friend who was food service manager for hotels explain the difference to me one time.  The corned beef hash example was a real one.  I was at a breakfast buffet and corned beef hash came out.  I jumped on it because it is a favorite but I realized it was cold.  Called the manager over and told him about it.  He looked like he had been shocked with a cattle prod, thanked me, and immediately went over and pulled the hash from the table before somebody got sick.

Temperatures inside a pressure cooker are hotter than ordinary steam, so it would sterilize things effectively.

Side comment - anything you'd cook in an ordinary pot will cook more quickly in a pressure cooker. It's especially useful for recipes that include dried beans or peas.

What I've read says 160f / 71c for 30 minutes will kill coronavirus.  But it is one of the least-recommended options.

We have an autoclave. And, basically, all it is is a pressure cooker.

I remember when Mom got it, I made that comment.

I'm sure it would work.
