Good point!

I had this problem even on newer vehicles like my mother's Fiat Punto. It used to freeze and then it's a pain to open. I even went to a mechanic shop and asked for any good products but they told me nothing could possibly help if it's really cold and water ices up inside the system, from rain and normal humidity. I ended up leaving home in the mornings with a bottle of hot water to de freeze it every time.

they have deicing sprays. but anything with 90% + alcohol will work. i've used hand sanitizers before to de ice
