If I have 6 cloth masks, and rotate them every day... giving days off... will the virus die off in the 3-4 days I don't wear them.
I don't have a mask on long... I'm sticking close to home.
What does DU think.

(101,730 posts)In the hottest direct sun within a parked car in summer time, it is possible to reach those temps.
BTW, you will see a lot of misunderstandings over heat versus UV light inactivation with some poorly informed writers indicating that ozone layer prevents sufficient UVC wave light to penetrate (BS) as do treated UV-blocking windshields (real issue). But they do not understand that it is dry HEAT, not UV that HCWs and others are relying on to inactivate when they rotate masks on their car windshields.
UVC, by the way DOES inactivate the virus readily and some are buying bags and boxes with UVC lights. The problem is that there has been no validation of these various items to prove the UV-C generated is sufficient, so buyer beware. SOme HCWs are buying them anyway and running their masks through them AFTER several days of dry heat exposure as an added measure.
But, if you are only wearing cloth masks, washing in soapy water and drying them is your best bet.

(31,261 posts)In terms of the virus, it should be as good as new. But if you ate an onion cheeseburger and spoke while wearing it, maybe washing it in warm soap and water before the sunshine may be a good idea.

The Cornona "shell" is destroyed by contact with soap. If you lather it up lightly after wash & rinse-then wring it mostly dry-this will leave a small amount of soap behind. Leave it to dry in the sun if possible.
Theoretically this will help destroy any virus that it comes across. And I don't mind the scented part it goes away fairly fast.

I also wash them regularly.

My wife is a front line health care worker. When she gets home from work she throws all her stuff in the plastic "biohazard" bin and heads straight for the shower. I wash her clothes with sanitizer.
That's in addition to the decontamination she does when she leaves work.
I hate this.

(23,374 posts)Best to fold them inward and put them in a paper lunch bag. Wash or sanitize your hands after putting the mask on again.

(44,962 posts)Think of all the bacteria you are breathing out, even if you stick close to home and are not actually exposed to covid virus (that you know of). So it's best to wash them regularly. Some cloth mask should be washed by hand, some are machine washable.
After wearing, I leave my cloth masks to sit for a week or so, then wash them by hand and air dry, so they are clean for next wear. The reason for hand washing is that my summer masks are made of silk, so have to be hand washed.

(1,078 posts)I know that a virus is nothing more than a strand of DNA or RNA that is surrounded by a protein coat. The bonds that hold the viral proteins together are relatively weak. That's why the experts tell you to wash your hands for 20 seconds. That's long enough for the soap to break down the protein coat and the viral DNA/RNA has lost it's protective coat and it's pretty much rendered ineffective. So if you leave your masks in a mildly soapy solution for more than 20 seconds, I'm sure that alone would kill off any virus on them.
From what I've heard, but can't swear to is Covid will die on cloth in 72 hours. I'd like to point out that when the experts tell you to wash your hands for 20 seconds, what they should be saying is to work the soap into your hands for 20 seconds then rinse with a lot of friction and copious amounts of clean water.
I hope this helps.

(13,453 posts)There was a lot of speculation back when this first started about things being contaminated for a week or 2 weeks and how long it would be on various materials. I can't find the source, but the latest I saw is that outside a host (a person) for awhile the virus doens't do to well, especially with no liquid. The reports of finding the virus on things a week later turned out to be that the RNA of the virus was being found, the broken remains after it's demise.
I'm putting gloves and masks in paper bags and letting them sit for a week. I feel that is probably sufficient.
You should probably do what you feel comfortable with.

(19,549 posts)I wash all my masks I've wore in hot water (and heat dry them, but I have a small frame.) on Sunday. I wear one per day, only. I, too have 6, but I don't need that many right now. My reasoning is JIK something changes I want to be ready. Everything is so in flux these days.

Or throw them in the washer and wash and/or dry with heat, whichever's convienient and will have the mask ready the next time you need it

(90,202 posts)I have a stash of N95s left over from the last big regional fire, but they are painfully uncomfortable. The first two cloth masks were gifts from my SIL, but the elastic is too short and hurts.
From Amazon I got a 5-pack of white cotton washable face masks, brand name VTER, $19.95. Theyre comfortable for me, 2 thick layers, and machine washable. I am just not out of the house that much to worry about running out, but I do like being able to use one for my errands and then put it in a mesh bag for washing. Turns out Im sanitizing all my purchases like crazy when I get home, and re-wearing the mask for the next day just doesnt feel right.
Yesterday when we were at Costco I saw a multi-pack that was very affordable, $12 for 4 I think it was. Those are machine washable, polyester/spandex, 4-pack face cover, brand name 32 Degrees Cool. They are black, stretchy, thin, and light, and I see a lot of people wearing what looks like the same thing. Sometimes they wear a colorful cloth mask over it, which is what I may do since 32* Cool is a single layer.
Thats all. Everybody has to find their own comfort zone these days.
