More to it then that? Lol
Very simple. Enough heat for enough time is expected to deactivate a certain percentage of virions. And don’t do a linear extrapolation of temperature downward. It doesn’t work like that.
No, it’s exponential.
I’m looking and just can’t find studies at the high temps and brief times of heating chambers, baseboards, or radiators.
Maybe tomorrow.
Two hours at 150F.
Which is too slow for home heating.
But your oven set on “warm”/170F for an hour would likely do just fine.
Along with 1/2 cup household bleach per gallon of water for clean surfaces that will tolerate it.
