And what not to do
For former boy scouts and other people whose motto is 'Be Prepared', you can buy a plastic windscreen cover which is placed on the car windscreen the night before a big freeze. It will get frosty, the windscreen won't.
Lukewarm water will clear the frost from your windscreen but be careful how you use it as it too will freeze over in very low temperatures, potentially leaving you with a slip hazard on the path. Ensure that you use recycled water, perhaps from a bath or shower.
Remember to keep a cheap plastic scraper in the car. It’s much better than using a credit or debit card, which could be damaged. An old plastic spatula or credit card you no longer use will also do the trick though.
Sit and wait
For people without the luxury of a windscreen with inbuilt frost clearing technology, there’s always he option to sit and wait while the heat from the engine and the car’s heating system kick into action.
Keep an eye out for de-icer in pound shops. It’s much cheaper than it used to be and is handy to keep in the house and car. If you still use a traditional key to gain entry to your car, remember that your locks could freeze too. If the de-icer is in the car and you’re outside it, you won’t be able to get to it!
Top up Screen Wash
Ensure that your screen wash bottle is topped up and that the levels are correct for winter driving. Salty roads can quickly make a windscreen dirty and you are going to need to clear it more often than normal.
Never Leave A Car Unattended
Never leave your car empty and the engine running while the windscreen defrosts. Thieves are on the lookout for cars just like that and you might find that it’s not covered by your insurance cover if the keys are in the ignition when it’s stolen.
Don't Use Your Windscreen Wipers
It can be tempting to use your windscreen wipers in an attempt to “snow plough” the ice and frost away. Doing this can damage the rubber wiper blade and shorten their life.
Avoid Using Cardboard In Wet Conditions
Using an old piece of cardboard is a cheap and cheerful alternative to a plastic cover but it can cause problems if it gets wet and then freezes, leaving you to clear frozen mush from the windscreen. Don’t use cardboard if you think it might get wet before freezing overnight.
Never Use Boiling Water
Never use boiling water to clear your frosty windscreen. The extremes of temperature could cause the glass to crack.
