Here's something to keep in mind as the weather gets colder out there; if your hand sanitizer freezes overnight, throw it away.

It's not the cold weather messing up the hand sanitizer, but if it freezes at all, it wasn't good in the first place. Hand sanitizers are alcohol-based, so they shouldn't freeze until the temperature hits nearly -130ºF. So if it does freeze, it means there wasn't enough alcohol to make it effective.
