I’ve come across a couple of ice packs that are close to their expriy date. I don’t know if I should attempt to use them after this date anyway. It’s not like dressings where they may not be sterile but wondered if the chemicals degrade and wont work so well. Anyone know? Not staying cold for so long would hardly be a problem, not getting as cold wouldn’t be ideal but much better then nothing, getting too cold and causing burns would be bad.
