With the UK set to be hit by an icy blast, one man who should know has revealed the quickest way to clear your windscreen in the mornings.

Former NASA engineer Mark Rober has uploaded a video explaning how to defrost car windows using the power of science – and four straightforward steps.

Forget newspaper, or de-icing spray or snapping your credit card in an attempt to scrape ice off your windscreen – there is an easier way.

The four steps:

Step 1: Turn ON the heater at full blast – hot air can hold more moisture.

Step 2: Turn ON the air conditioning – this will help soak up the remaining moisture from the air.

Step 3: Turn OFF inside air circulation – winter air doesn’t have much absorption so keep it outside the car.

Step 4: Open the windows ever so slightly – for a few seconds, this will help exchange humidity in the car for the dry air outside.

If that’s too ordinary, and you’re a fan of MacGyver, Rober also has methods involving cat litter and shaving foam.

The full six-and-a-half minute video explains the science behind the four steps.

Curiosity Rover

Rober was at NASA for nine years, seven of which were spent working on the Curiosity Rover.

He left NASA and began creating ‘wearable tech’ Hallowe’en costumes – you may remember that he was behind the ‘hole in the torso’ costume, which used two iPads to create the illusion of a gaping hole in his body.

Happy windscreen-clearing!
