For millions of Britons, the winter morning ritual of scraping ice from a car windscreen is a dreaded, time-consuming chore. However, a simple and surprisingly effective hack, demonstrated by a social media-savvy dad, is challenging the need for traditional scrapers and de-icer sprays.
The Viral Sandwich Bag Method
The trick, shared on TikTok by user dad.hacks0 on 12 January 2026, requires just one household item: a sturdy sandwich or food bag. The method is straightforward: fill the bag halfway with hot, but not boiling, water, seal it tightly, and then gently wipe it across the frosted glass.
In the video, set to Vanilla Ice's 'Ice Ice Baby', the ice is shown melting away instantly upon contact with the warm bag. The creator claimed the same bag of water defrosted both the windscreen and driver's side window in under a minute, offering a rapid solution for those rushing to work or the school run.
Public Reaction and Safety Debate
The hack garnered significant attention, with many viewers impressed by its simplicity and speed. One user commented they had used a similar method with a warm 2-litre soft drink bottle for years.
However, the technique also sparked a safety debate. A concerned viewer warned it could cause thermal shock and create micro-cracks in the glass. dad.hacks0 countered this, emphasising the use of hot, not boiling, water to safely melt the ice without damaging the glass. Another user claimed to have used the method for 15 years without issue.
Official Advice from the AA
While creative hacks circulate online, motoring organisations like the AA recommend a more conventional, thorough approach for safety. Their step-by-step guide is as follows:
- Ensure your windscreen wipers are switched off to prevent motor damage if frozen to the glass.
- Start the engine and turn the warm air blower to the windscreen. Activate the rear window heater and heated wing mirrors if available.
- Switch on the air conditioning to help demist the interior by removing moisture.
- Use a brush to clear any snow from the car's body.
- Finally, use a proper ice scraper and de-icer fluid to clear all windows completely.
The AA stresses that drivers must not set off until all glass is fully clear for maximum visibility and safety.
Whether you opt for the quick TikTok fix or the comprehensive official method, the key takeaway is to plan ahead during frosty spells. Ensuring your car is safe and clear to drive is a non-negotiable first step for any winter journey.
