Car windshields filter UV though (unless you are talking about heat generation)...

twospoons:
The problem with UV is shadowing. Heat or an alcohol soak would be better as they will penetrate the cloth, where UV will only disinfect the outside.

rdl:
Intensity of any local source of UV light is going to fall off rapidly. I'm not sure you'll be able to to kill much of anything. Chemical or heat sterilization is probably best.

Works but probably 400% overkill and possibly damaging to the masks.

I'm not sure about overkill, a domestic pressure cooker it would probably be hard pressed to reach the required 130'C. Remember the mask would only be exposed to steam, not the boiling water. It would probably be a lot more gentle than dry uneven heat in a microwave.

130 degrees C is required to make sure something like surgical equipment in hospital is 99.999999% free of ALL pathogens. We are now interested mostly killing some wimpy viruses, not bacterial spores or prions.
And even less than perfect result is better than nothing when you are in nearly war-like situation like Italy.
If 60 degrees is good enough for Ebola I see COVID no different.

yes all the replies are a pile of bullshit, some will just destroy the mask, other will make it toxic or not provide any sanitation

scientific literature (use proper search engine on the net to find that) proves that both ethanol and isopropanol destroy the capsid (the protein shell of the virus) in 30 seconds
