I found another link specific to Covid-19. They said the same thing - normal cooking temperatures will destroy it.
They also say to wash clothing and towels at 140 degrees. But everything that I have read says that the washer and drier temperatures are too low to destroy it. BUT - the washing with detergent does break down the protective envelope to destroy the virus.
Just putting clothing into the drier MIGHT heat it up and dry it out (the envelope needs moisture), but I’m not sure I would depend on just that.
Thanks.
Temp and covid info is hard to find.,
