We recommend allowing about 10 minutes to clear your windscreen thoroughly using a scraper and de-icer if necessary. Don’t forget about the other windows and your mirrors as well … they’re just as vital for safe visibility and are often ignored, limiting your vision, especially at junctions.
Don’t be tempted to pull away until the windscreen is fully clear – it can be dangerous and the Highway Code states it is illegal to drive with poor visibility.
Plan ahead to save time in the mornings, either by putting an windsreen cover on the night before or getting up a little earlier so you have plenty of time to de-ice your vehicle.
Never pour hot or boiling water on your windscreen, otherwise you run the risk of cracking the glass and an expensive repair bill. If you don’t have any de-icer, you could use lukewarm water.
It’s also a good idea to carry a lock de-icer with you to clear your lock. If your locks do get frozen, try warming the key or spraying de-icer or an oil-based lubricant into the lock.
Finally, ensure all your vehicle lights, front and rear, are free from frost and/or snow – a thick film of frost on the lens can affect the intensity of the lights, making it difficult for other road users to see you or your signals.
If you use the vehicle’s heater /screen demister, don’t leave your car unattended while you wait for it to defrost as you run the risk of having your vehicle stolen.
