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.
