The facts surrounding having hand sanitiser in hot cars.26 June 2020
Earlier this week, reports appeared stating that hand sanitiser shouldn’t be kept in cars during high temperatures due to the risk of it causing fires in the vehicles.
‘Experts’ were stated as saying that the ethanol in the product released flammable vapours which in turn could combust.
However, fire brigade experts were quick to respond, with the National Fire Chiefs Council tweeting "Hand sanitisers kept in Hot Cars DO NOT pose a fire risk"

In fact, the auto-ignition point for alcohol-based hand sanitisers would be similar to ethanol at over 350°C without spark.
So the lesson here is, people who have chosen to keep hand sanitisers in their car no longer need to worry and are safe to continue.
