AA warns drivers to do quick 5 step routine to de-frost car windscreen

The AA is urging drivers to stop using online hacks and to instead to follow a quick simple guide which will ensure they don't damage their vehicle. Car owners are being bombarded with so-called hacks online that may look like they work, but in fact do not.

'Hacks' such as putting hot water in a sandwich bag to defrost a windscreen is advised against as the melted ice could refreeze and cause your windscreen wipers or even door handles to stick. Another trick you should not do is rub half a potato slice on the inside of your windows to stop them steaming up as this could do the opposite and smear them meaning you won't be able to see and therefore drive.

They are not the only experts to issue a warning with the gurus from Windscreen Wipers stressing drivers need to stop falling for online hacks. The experts caution: "Using water of any temperature to de-ice windscreens is not advised. Hot water will cause the glass to expand, which can result in it cracking or even shattering, and cold water can freeze on top of existing ice and frost. Both methods can damage your windscreen, sometimes beyond repair."

Experts at AA, back up this method stating: "If you use hot water for the ice on your car, you run the real risk of damaging your windscreen. Glass expands quickly when hot or even warm water touches it. But it'll contract quickly too as it cools down in the cold air. That flexing can make the glass crack even if you're using lukewarm water – especially if it had small chips or cracks already."

So how do you defrost your car? Here is what you should do

The AA's safe car de-frost method

1. Check your wipers

Before you do anything, make sure your wipers are not on and they're not frozen to the windscreen.

2. Start the engine

When you start the engine, you should turn on the warm air and face it towards the windscreen, and if you have them you can now also turn on your heated mirrors and rear windscreen.

Then turn the air con on which will help the car to stop misting up. If you need to wipe, do it with a lint-free, absorbent cloth the AA warns as you could leave smears behind.

3. No snow

Remove off all the snow from your car and that there is none left anywhere such as on the front, the top or on any of the lights.

4. Scrape while you wait

Use a scraper and de-icer on the outside whilst the inside is warming up.

5. Drive

Once all the steps are complete, ensure the glass is all clear and you are good to go.
