Does hand sanitizer lose its effectiveness?
Hand sanitizer does expire, usually about three years after its manufacture date.
Hand sanitizer expires because its alcohol content dissolves over time — once it drops below 60% alcohol, it won’t be as effective at killing germs..
Does heat ruin hand sanitizer?
A car can heat up very quickly in the sun, so it’s better to leave your hand sanitizer in a place where the temperature is cooler. In addition, there are some concerns that evaporated alcohol from hand sanitizer in hot temperatures could cause combustion or explosion — but this is very rare.
Can you eat food after using hand sanitizer?

How do you test alcohol in sanitizer?

Is hand sanitizer highly flammable?

Is it safe to leave hand sanitizer in a hot car?

Can you use hand sanitizer to start a fire?
