Sort of a bio/academic question. Will microwaves (as in the mike in your kitchen) kill viruses? Application: For the sake of discussion, let's assume a virus as virulent as the Spanish Flu of 1918 whacks the human population again. Would microwaving letters and other objects that are microwavable kill all bacteria and viruses? My eons-ago bio classes (didn't even have microwave ovens back then ) tell me that it should kill anything organic including viruses, but I have never seen any directives or advice to that effect. Any bio-brains out there in prepper land who knows for sure? Could come in handy to know these things -- think "mail box".
