One more thought:
If you're using home made fabric masks
In Addition to washing them with detergent, Personally I would steam IRON them ...
notice that HEAT & Humidity method above actually requires 30 minutes of exposure at 60C (140F)-75C (167F)
But, an ironed, crisp freshly pressed shirt and mask may look more neat. ( I don't know LOL, but it couldn't hurt to steam iron a fabric after washing)

THE HYDROGEN PEROXIDE STEAM METHOD REQUIRES TRAINED PERSONNEL & EQUIPMENT AS IT'S DANGEROUS
HEAT & HUMIDITY IS PRETTY SPECIFIC, THE uv LIGHT IS WHAT i DECIDED TO POST ABOUT AFTER HEARING STORIES OF PEOPLE USING 1970S BLACKLIGHT POSTER BULBS ON THEIR MASKS DUE TO HEARING "UV LIGHT DISINFECTS"
Only UV-C wavelengths will disinfect ... and "shadowing" means all parts if multilayered masks (such as 3-ply surgical masks/ in between folds etc) exist etc may prevent parts from getting a "dose"

Stay safe y'all

To disinfect a mask, there are 3 approved ways (NOT talking about home made cloth masks where detergent and friction can destroy virus like in hand/MACHINE washing but the N95 or other respirator type maske

https://www.n95decon.org/

The UV-C light is NOT the old UV Blacklight poster purple light nor is it UVB suntan bulb light nor is it the UV-A buglight bug attracting UV light


CHECK THE NANOMETER WAVELENGTH before buying a "BUG ZAPPER/Blacklight Poster/Suntan" bulb that scammers advertise as a "UV Ultraviolet disinfectant bulb"
UV-C light is approved to decontaminate n95 masks (As are 2 other methods but NOT alcohol bleach etc) some places may have KN95 masks in stock if you cannot find any N95 masks if EMS or someone you know might need this info
See chart Page 2 Technical Bulletin Comparison of FFP2, KN95, and N95 and Other Filtering Facepiece Respirator Classes https://multimedia.3m.com/mws/media/179 ... ses-tb.pdf
FDA changes course and allows KN95 mask to be used in US https://www.cnn.com/2020/04/03/politics ... index.html
F.D.A. to Allow Use of KN95 Masks https://www.nytimes.com/2020/04/03/heal ... masks.html

The masks are almost identical in performance to the N95 masks that hospitals and other institutions are struggling to find.

P100 mask filters 99.7% and the "P" (instead of "N") means Petrol/oil vapor resistance, 3M makes pink ones that screw fit onto their respirator masks

N95 filters about 95% and the "N" instead of a "P" means NOT Petrol/NOT OIL vapor resistant

Other masks rated 94/95% you can see in chart on Page 2 such as

KMOEL, KN95 etchttps://multimedia.3m.com/mws/media/1791500O/comparison-ffp2-kn95-n95-filtering-facepiece-respirator-classes-tb.pdf

I have some UV C lights ordered to decontaminate masks & stuff do NOT look at the light (Cataracts) or be in room with light a long time (skin damage) ..air out room after done using light . Air out room 30 minutes or use lights with windows open if they are OZONE creating (sterilizes but can harm lungs in large concentrations Smells like after a thunderstorm) https://www.n95decon.org/caution

1) best = FAR UVC UV-C 207–222 nm less harmful to humans skin & eyes long term very expensive impossible to find right now

2) good for medical = UV-C, sky blue color from 100 nanometers (nm) to 280 nm.
Above Far UVC and UV-C disinfect kill bacteria, may affect DNA of Viruses

Below UV light gives sunburns sun tans harms eyes with cataracts & can cause skin cancers
3) UV-B, from 280 nm to 315 nm.
4) UV-A, from 315 nm to 400 nm. attracts bugs to bug zappers, UVA's longer-wavelength rays can damage the skin's connective tissue
UVA's longer-wavelength rays can damage the skin's connective tissue, leading to premature aging as well as play a role in causing skin cancer. •UVA rays also increase the risk of cataracts and retinal damage •Tanning beds emit two to three times the amount of UVA that reaches the earth outdoors.1•UVB causes severe sunburns •Both UVA and UVB cause skin cancer •UVA can burn and when it does it burns more deeply and severely than any other UV wavelength. •Studies show that UVA depresses the activity of immune cells in the skin and perhaps in relation to this, exposure to UVA can evoke bacterial infections in the skin.2
============
On Ebay UV-A lights like below (and UV-B) are being sold for disinfection ...
that's a scam & harmful to Humans CHECK THE BULB'S WAVELENGTH BEFORE GETTING SCAMMED
This light is UV-A good for attracting BUGS not disinfection
E27 3W
Ultraviolet led UV Light Bulb Sterilization Lights Germicidal Lamp Bulb
Wavelength: 395nm
Color Temperature: 395NM
Do NOT buy such devices...

THERE are REAL UV-C bulbs (many available in USA stock) on Ebay/Amazon that ship much faster ...CHECK THE NANOMETER WAVELENGTH !!! Yyou don't need to order from scammers or China.

DO NOT LOOK AT THE UV LIGHT ELSE YOU CAN GET CATARACTS
DO NOT EXPOSE SKIN TO UV LIGHT FOR LONG ...IT CAN HARM DNA/RNA AS IS FOUND IN BOTH VIRUSES AND HUMANS

yeah true.

And, since no one has taught me how to DON and DOFF shoes without touching them ... because CDC says that the virus can travel on our shoes (without stating on the top, where particulat mist drops may fall, or the bottom of the shoe where we step in it0 I'm going to wear flip flops. We, my church, just had our annual communion Feet-Washing in March, so I'm good for another year.

I read that Jesus wore sandals too

I try to make at least 1 person smile or laugh every day.
We need humor during these times.
As Instant Powdered cow milk is scarce, I donned my gloves to go get some "Powdered Goat Milk" but was unable to locate a "Powdered Goat"

This probably deserves it's own thread, so here
There is a RIGHT way and lots of WRONG ways most never think about unless they're in medical field or took CERT type training
