British drivers facing frosty mornings can now clear their windscreens in half the time using a simple, cost-free technique. This clever hack, which requires no special equipment, promises to slash frustrating wait times and get you on the road faster during the winter chill.
The Common Mistake That Slows You Down
Most motorists make a critical error as soon as they discover their car is iced over. The instinctive reaction is to immediately turn the vehicle's blowers and heated windscreen to their maximum settings. However, according to experts at National Tyres and Autocare, this common practice is counterproductive and actually prolongs the defrosting process.
When you blast hot air onto a freezing cold windscreen, the sudden and extreme temperature difference can cause stress to the glass. More importantly, it creates a layer of condensation on the inside of the screen as the warm, moist air from the cabin hits the cold surface. This results in a frustrating double layer of ice and fog that you must clear.
The Step-by-Step Guide to Faster Defrosting
To defrost your windscreen effectively and twice as quickly, you should follow a more measured approach. Start by turning on your engine and setting your blower to a cool or lukewarm setting, directing the air towards the windscreen. The key is to gently raise the temperature of the glass, not to shock it with heat.
Simultaneously, activate your rear window heater to begin clearing that glass as well. Crucially, you must also switch on your air conditioning, even in the depths of winter. The AC system acts as a dehumidifier, stripping moisture from the air inside the car and preventing that interior fog from forming.
Only once the blowers have been running on a cooler setting for a few minutes should you gradually increase the temperature. This method allows the glass to warm up evenly, clears existing condensation, and prevents new mist from developing.
Essential Safety and Legal Advice
While waiting for your screen to clear, it is vital to remember the law. Rule 229 of the UK Highway Code is explicit: you must be able to see clearly out of all windows before you set off. Driving with obscured windows is not only dangerous but can lead to a hefty fine and penalty points.
Experts strongly advise against the risky shortcuts some drivers take. Never use boiling water to de-ice your screen, as the thermal shock can cause it to crack or shatter. Similarly, avoid using your windscreen wipers to scrape away ice, as this can tear the rubber blades and potentially damage the wiper motor.
The safest tool for the job remains a proper ice scraper and de-icer spray. A little preparation, like using a windscreen cover overnight, can also save you time in the morning. By combining this gentle, staged heating technique with proper scraping, you can ensure a clear view of the road ahead and a safer, quicker start to your winter journey.
