They’re still sealed. Have been in a dark cabinet.
I opened one...whoa!...very strong (91%).
I’m using it to spray the mail, then I set it (the mail) out in the sun.
Thinking this should kill it!
I got some bags of flour and pancake mix today and they put them in a cardboard box for me.
When I got home, I opened the hatch to the SUV and let the sun hit them for a couple hours, then turned them all around so it would get the other side.
Closed it up and locked it and will deal with it in a couple days. sitting in the car at these cooler temperatures is not going to hurt it.
BTW, I’ve seen the info about how long the virus survives on different surfaces. What about regular paper, like mail or cereal boxes, etc? I know cardboard is about 24 hours. Plastics and metals are longer but nobody says anything about coated paper.
Or fabric, like your clothes.
