Car defrost

You'd think that with March approaching, we wouldn't still be needing to defrost our cars in the morning, but nope.

With hugely frosty mornings returning this week, you'll probably be finding yourself clearing the windscreen in a panic if you drive to work or need to drop the kids off at school.

Sadly, thieves can often appear when commuters are defrosting their windscreens. In November 2016, a car was stolen every five minutes as people left their cars running unattended.

Dean Hill, AA AutoWindshields technician of the year, said a lot of modern cars can be very difficult to steal without keys, but warned: "To car thieves, frosty mornings are a gift."

Thankfully, the AA has provided a handy guide for a speedy de-icing:

1. Stay with the car at all times. If you have to back inside, switch the car off and lock all doors.

2. Do not drive away until all of the glass is fully clear.

3. Do not leave wipers in 'auto' when frost is expected the next day. If the wipers are frozen, the wiper motor might get damaged. Do not attempt to force any frozen wipers off the glass.

4. Do not use boiled water to clear glass, as it could crack the glass, and ice your wipers to the glass.

5. Clear all snow off the car using a soft brush is effective. Also make sure the front grille is clear, or there might be a risk of the engine overheating. Make sure the lights are clean and working.

6. Air conditioning will help to dry the air and keep the cold glass mist free.

7. Do not use your hands to wipe misted-up windows. This will leave greasy smears. Use a lint-free absorbent cloth instead.

Plus, a few other tips:

  • Rub half a raw onion on your windows and windshield the night before a potential freezy morning. This trick keeps frost from forming on the glass.
  • Or spray it with vinegar or alcohol mixed with water to avoid frost.
  • Cover your windshield with a folded sheet, using the wipers to keep it in place.
  • Rub any freezing blades with alcohol, as this will keep them from sticking to the window.
  • Cover side mirrors with carrier bags the night before, and keep them in place them with rubber bands.
