If I cannot buy bleach what makes this person think I can find the substances to make my own?
Liquid bleach has a terrible shelf life compared to pool shock.
So when storing supplies for emergencies, store pool shock with a 10 year life vs bleach with 6 month.
That’s the point of the article
The article is all about shelf life. Liquid bleach loses its properties, so that in a few years a bottle of bleach is not a reliable disinfectant. Solid (granules) of pool shock have a 10 year shelf life with no degradation at all.
As for me I've already brought two 2lbs. bags and placed them in a empty plastic coffee can and added to my preps.
I think the point of the article is that you can buy the ingredients ahead of time since the ingredients themselves will stay fresh much longer than bleach.
All would have been explained if you'd read the article. That jug of bleach in your laundry room has a shelf life of 6 months before it starts to lose effectiveness. The Pool Shock has a shelf life of 10 years. Pick up a pound of it at Wally World for $5 now before TSHTF. As in all prepping, you do it now or you become one of the hoards of zombies the rest of us will be guarding our homes against.
“If I cannot buy bleach what makes this person think I can find the substances to make my own?”
The idea is to buy substances to make the bleach NOW, since they have a longer shelf-life than the bleach itself. Then, when you need them, you will already have them.
