46. A Science Note On This

Mon Apr 13, 2020, 08:35 PM

I'm not surprised to see this.
MedTech microwaves are likely tunable, so the exact frequency can be dialed in to the resonant frequency of the hydroxyl in the protein head.
Consumer microwave oven are fixed tuning, and the frequency is aimed at the dipole moment of water.
There's no water in the virus, or any to speak of in the mask.
So, putting the mask in the oven probably doesn't heat the mask very fast.
Since it's not tuned directly to the virus, and the mask won't get super hot, it makes sense that it's better to wash them.

Wouldn't ironing it also kill any virus? Siwsan Apr 2020 #1

there is no soap in that treatment. Soap is required TeamPooka Apr 2020 #2

Ahhh. I thought heat, like an autoclave, would also kill the virus Siwsan Apr 2020 #3

The soap breaks down the protective fat layer surrounding the virus protein TeamPooka Apr 2020 #5

High Heat Destroys It Anyway ProfessorGAC Apr 2020 #37

This virus is digested in the stomach after eating it. uppityperson Apr 2020 #29

I'd put that in the "cold comfort" file eleny Apr 2020 #31

This virus can not survive the digestive process. At least it hasn't been found to so far uppityperson Apr 2020 #33

You need soap and water. xmas74 Apr 2020 #4

Then I could hand wash the mask, too, in hot soapy water. Siwsan Apr 2020 #7

yes hand wash, maybe put em in a pan with soapy water and boil a minute or two nt msongs Apr 2020 #25

That's what I do. Soap it up well with warm water and lots of bubbles, wash and scrub it by hand, Nay Apr 2020 #30

Me, too eleny Apr 2020 #32

Sorry, not sure SheltieLover Apr 2020 #8

UV-C light is one way hardluck Apr 2020 #20

I've been using a UV wand....should work. Sancho Apr 2020 #60

Here you go hardluck Apr 2020 #19

Thanks for that. Disaffected Apr 2020 #21

Any virus in the oven would die and you could always turn it up to a higher setting to be sure hardluck Apr 2020 #24

Or take the mask out and then turn the empty oven up another 30 degrees? dawg day Apr 2020 #51

N95s are not meant to be reused, so use caution. KY_EnviroGuy Apr 2020 #28

And if your mask has a metal nose piece (all the ones I make do) catrose Apr 2020 #10

Yes, good point! SheltieLover Apr 2020 #14

Depends on the shape of the metal. Disaffected Apr 2020 #16

Potatoes? Disaffected Apr 2020 #44

I wonder if using one of those clothing steamers works? kimbutgar Apr 2020 #15

Not sure SheltieLover Apr 2020 #18

You can steam, but it has to be for 10 minutes. PeaceNikki Apr 2020 #22

I have a food steamer that I use to reheat food rather than use the microwave kimbutgar Apr 2020 #23

Better yet, don't go out unless absolutely necessary. cwydro Apr 2020 #27

I do wonder about the mail and newspapers though. Disaffected Apr 2020 #35

Why would you sterilize ANYTHING in a device where you prepare your food? brooklynite Apr 2020 #63

Personally, I would not, on either count! SheltieLover Apr 2020 #66
