Let's talk bleach

Pool chlorine tabs are the same thing.
It's all calcium hypochlorate.

Or you could just make your own chlorine.

The problem with making your own is finding electrodes that aren't effected by chlorine or hydroxides.
Something like gold or platinum that supposedly will become totally useless after shtf....

 

I avoid bleach like the plauge.
I worked cleaning appartments when I was a teenager and apperently developed an allergy/reaction to it.
The smell gives me the mother of all headaches now. If we need something bleached, my dh has to do it and I have to be out of the house untill its been rinsed away and the smell evaporates.
You can get the thin bleach here but it takes some looking, mostly places carry 101 versions of the thick bleach... dosent mater what they say it smells like (Pomegranate spice? ) still gives me a headache.
