If you ever leave hand sanitizer in your car this winter and find it FROZEN the next morning, throw it away! It’s not because cold weather ruins it. It’s because if it freezes at all, it was probably no good in the first place. Most hand sanitizers are alcohol-based. So they shouldn’t freeze until the temperature gets REALLY low: like negative-50 degrees or lower.
So if it does freeze, it means there wasn’t enough alcohol in there to be effective… or it was a cheap knock-off that didn’t have the ingredients listed on the label. Almost all the brands you see at stores contain alcohol. So if yours freezes, check the label. If it’s alcohol-based, throw it out!
