Three Expert-Approved Ways to Defrost Your Car Windscreen Fast
Three easy ways to defrost your car windscreen

As the mercury plummets across the UK, the dreaded morning ritual of scraping a frozen windscreen returns. Being late for work because of a frosted-over car is a common frustration, but a leading motoring expert has now shared three surprisingly simple methods to break down the ice almost instantly.

The High Cost of a Frosty Windscreen

Before you consider setting off with a partially cleared view, it's crucial to know the risks. Driving with an improperly cleared windscreen can be deemed 'using a vehicle in a dangerous condition'. If caught, you could face a hefty fine of up to £2,500 and receive three penalty points on your driving licence.

Richard Evans, head of technical services at the online car-buying service We Buy Any Car, has outlined the most effective techniques to tackle the frost swiftly and safely.

1. Harness Your Car's Heating System

The first and most common method involves using your car's own resources. Evans advises: "Switch on your engine and turn the warm air blower towards the windscreen." For an even faster result, he recommends also activating the air conditioning.

This helps to remove moisture from the air inside the car, significantly speeding up the defrosting process. A critical safety warning accompanies this tip: never leave your vehicle unattended with the engine running, as this makes it a prime target for 'frostjacking' car thieves.

2. The Vinegar Solution Spray

For a quick pre-emptive strike, you can create a homemade defrosting spray. The recipe is straightforward: mix three parts white vinegar with one part water in a spray bottle.

Simply spray the solution onto your windscreen before you head indoors for the evening or as you prepare to leave. The vinegar works by lowering the melting point of the ice, allowing the water to clear the glass effectively. Evans cautions not to use this method if your windscreen is already cracked or chipped.

3. A Saltwater Mixture

Similar in principle to the vinegar trick, a saltwater solution also attacks frost by reducing its melting point. Dissolve one tablespoon of salt in water, ensuring it is fully mixed, and decant it into a spray bottle.

A light spray directly onto the frosted glass will do the job. The expert warns against pouring on large quantities, as the salt can damage the car's bodywork paint over time. A modest application focused on the windscreen is all that's needed.

Additional Advice from The AA

The AA has echoed the advice about using air conditioning in winter, stating it is "not just for summer" and is excellent for demisting the interior. They also offer a practical tip for clearing mist: avoid using your hands, which can leave greasy smears, and never use a diamond ring, which can scratch the glass. Instead, use a lint-free absorbent cloth if needed.

With these expert tips, from using your car's climate control to whipping up a simple homemade defroster, you can save precious minutes on cold mornings and ensure your journey starts safely and legally.
