BTW, you will see a lot of misunderstandings over heat versus UV light inactivation with some poorly informed writers indicating that ozone layer prevents sufficient UVC wave light to penetrate (BS) as do treated UV-blocking windshields (real issue). But they do not understand that it is dry HEAT, not UV that HCWs and others are relying on to inactivate when they rotate masks on their car windshields.
UVC, by the way DOES inactivate the virus readily and some are buying bags and boxes with UVC lights. The problem is that there has been no validation of these various items to prove the UV-C generated is sufficient, so buyer beware. SOme HCWs are buying them anyway and running their masks through them AFTER several days of dry heat exposure as an added measure.
But, if you are only wearing cloth masks, washing in soapy water and drying them is your best bet.
