What is the shelf life of chemical heaters?
I know they don't last too long. My impression is they'll be ok next year, but not two years. Any ideas on how long you can store them before they harden and become useless?

RE: What is the shelf life of chemical heaters?
I always thought they would last forever, but I found ones I had from 2 years ago weren't working. I wondered if there was a small hole in the package and air was able to sneak inside someway. The ones I purchase last year worked this year though.
Might depend on the brand.
