A simple trick for frozen mirrors – does it work?

In the UK, winter is increasingly common, as cars are spotted with… socks on their side mirrors . This is a home remedy designed to reduce frost and ice build-up on mirrors and save time in the morning when you need to get out of the house quickly.

What is the trick?
In the evening, ordinary fabric socks are placed over the mirrors, acting as an insulating barrier . The fabric reduces contact between the mirror surface and moist, cold air, so in the morning the mirrors are less icy or do not require scraping at all.

Why does it work?
Car mirrors cool faster than the rest of the car because they're exposed to wind and frost. The sock material slows heat loss and reduces moisture buildup, reducing ice formation.

When does a trick work?
– works best with moderate frosts and no freezing rain ,
– may not replace traditional methods (e.g. defroster) in very low temperatures.

Why do drivers like him?
It's a cheap and simple method that doesn't require chemicals or special covers - all you need are old socks that everyone has at home.
