How long does liquid bleach store before losing efficacy?
A friend opened on of his storage shed and found two 1 gallon containers of bleach. They have probably been there 2 or 3 years.
I told him to toss them as bleach losses it’s effectiveness after only 1 year.
What say you?
Liquid bleach does lose effectness fairly quickly.
You might want to consider storing some Calcium Hypochlorite (Pool Shock). It retains its chlorine a long time and a little bit goes a long way. Instructions on its use are in my manual. WARNING do not store with your other preps. Calcium Hypochlorite is corrisive. I store mine in my paint cabinet sealed in mylar and in a used plastic coffee can.
well, If the container is sealed, it should last pretty much indefinitely. I don’t think chlorine will sublimate through the walls of the container or the lid. If the outside temp is high, the Chlorine should evaporate within the vessel and enter the gaseous phase but that should just result in an increase in pressure within the sealed bottle. If I were in doubt, I would just smell it and take a chance if it burned the nose a bit.
