When winter bites, few things are more frustrating than facing a frozen windscreen when you’re already running late. But beyond the inconvenience, not defrosting your windscreen properly can shatter any prospects for having a good day. Preventable damage or accidents linked to poor visibility could influence your car insurance claim. That’s why it pays to know the right way to handle those frosty mornings.

 

Why Windscreen Defrosting Matters 

Safety Implications of Poor Visibility

Driving with a partially defrosted windscreen can limit your vision and increase your risk of an accident. Obstructed views can prevent you from spotting hazards, pedestrians, or even other vehicles. Driving with impaired visibility is not only dangerous, but can also be seen as negligent, potentially affecting the outcome of insurance claims if an accident occurs.

 

How to Defrost a Car Windscreen Properly 

Step-by-Step Defrosting Guide:

  1. Start the car and turn on the heater. Set it to defrost mode and gradually increase the temperature.
  2. Turn on the rear window defroster. Most cars have a button for this. Let it run while the engine warms up.
  3. Use the air conditioning. This may sound odd in winter, but it helps to remove moisture from the air inside the car and prevents fogging.
  4. Gently scrape the ice. Use a plastic scraper or credit card to carefully remove ice as it starts to soften.

Using Hot vs Cold Air

Always start with cool or lukewarm air and slowly increase the temperature. Blasting hot air can cause the windscreen to crack due to thermal shock.

Common Defrosting Mistakes to Avoid

Why Pouring Water is Risky

It’s tempting to grab a kettle, but pouring hot water on a frosty windscreen can cause the glass to crack instantly.

Myths vs Facts: Boiling Water, Vinegar, and Salt

  • Boiling water: Too risky; avoid completely.
  • Vinegar mix: Can damage the glass or surrounding rubber seals over time.
  • Salt water: While it can melt ice, salt is corrosive and may harm your paintwork and wiper blades.

 

Tips to Prevent Frost Buildup

Night-Before Preparation Tips

  • Park your car facing east so the morning sun naturally warms the windscreen.
  • Keep your wiper blades raised to prevent them from sticking to the glass.

How to Cover Your Windscreen

  • Use a windscreen cover or even a towel or sheet of cardboard to block the frost from forming.
  • In a pinch, a plastic bag or garbage bag can do the trick. Just secure it properly to avoid it flying off in the wind.
