The AA has disclosed the fastest method to clear fog from your car windscreen in the morning. As winter descends upon Birmingham, the AA has provided the definitive technique for demisting your vehicle.

It explains the best way to defog windows is by using a combination of hot and cold air. "You should turn on your warm air blower and rear windscreen heater as well as your air-con," the AA said in a statement.

"If possible, allow some outside air to come into the car as well. This should help you quickly turn a frosted-over car back into something more drivable.

"[One] hack suggests rubbing half a potato onto the inside of your windows to stop them steaming up," the AA said, reports Birmingham Live.

"We wouldn't recommend rubbing anything onto your windows that could smear them and impair your ability to see the road clearly."

You can activate the air-conditioning to extract moisture from the air within the vehicle, which will help prevent misting."

The advice continued: "Avoid using your hands to wipe the misted-up windows as you'll leave smears, opt for a lint-free absorbent cloth if necessary," the AA added. "You should stay with your car the whole time while the engine's running and before you know it, your windscreen will start to clear up."

On particularly bitter days, the water could freeze before you realise it – and warm water actually freezes more quickly than cold water.

Should it refreeze, it will form a layer of ice on your windscreen (and on your driveway if any has been spilt). Even worse, it will accumulate on the wipers and freeze them to the glass, potentially damaging the wiper motor or tearing off the rubber if you activate them.
