Want a laugh? Look at the "Best by" date on table salt.

Bleach is a reactive chemical so it is constantly breaking down and will become less affective over time.

this is correct and I believe the smell is the breakdowns occurring.

Meh. Sure it breaks down. Does it mean you can't use it a couple years later? Nope. You may just need some more than normal.

Pretty soon lumber will have A best by date so you can't use it to build and the inspectors will look for it before passing.

Plastic is not necessarily air tight.

I've always noticed that if I leave a gallon of bleach in the sun it loses its potencey much faster.

So I make sure that it's stored in the shade and sure enough, it still has the "kick" it's supposed to.

Bleach degrades. Salt can get caked-up and be hard to use. Rubbing alcohol though?
