Facing a fogged-up windscreen on a chilly morning is a universal frustration for drivers across the UK. The usual remedies often fall short, leaving annoying smears or an uncomfortably cold cabin. However, a professional car detailer has shared a simple, effective solution he has relied on for more than ten years.
The Secret Is In The Spray
Ryan, known online as @ryanthedetailer, took to TikTok to demonstrate his go-to method for achieving perfectly clear, streak-free glass. His secret weapon is not a specialist product, but a common household item: diluted isopropyl alcohol. He insists this accessible solution outperforms many dedicated glass cleaners available in shops.
"My secret is diluted isopropyl alcohol, which is readily accessible in stores and online, and in my opinion, is better than any glass cleaner you'll find," Ryan explained in his video posted on 7th December 2025.
How To Apply The Method
The process is straightforward. Ryan advises applying a couple of sprays of the diluted alcohol onto a clean cloth, wiping the interior of the windscreen, and then immediately buffing it dry with a second, clean towel. This two-step process is key to eliminating the fog and preventing any residual streaks from forming.
When asked about the dilution ratio, Ryan clarified that it does not need to be strong. For a bottle of 99% isopropyl alcohol, he suggested a mix as weak as 20-25% volume with water would work effectively. He emphasised that users can always add more alcohol if a stronger solution is needed.
Important Considerations For Tinted Windows
The hack sparked questions from viewers concerned about using it on tinted windows, with some commenters warning against it. Ryan was quick to reassure them, stating he has used it without issue for 15 years.
"It will work fine on tinted windows. I haven't had a single problem in 15 years. It's diluted, as long as your tint isn't falling apart already, there won't be a problem," he responded. Nevertheless, he and other experts recommend conducting a discreet patch test on a small area first to ensure compatibility with your vehicle's specific fittings.
Why A Clear Windscreen Is Crucial
This tip is more than just a convenience; it's a matter of legal safety. The RAC warns that driving with an obscured windscreen is against the law and can result in a fine or penalty points. Their official advice for clearing condensation aligns with using dry air, recommending drivers use their car's heater in conjunction with the air conditioning to dry the atmosphere inside the vehicle.
Viewers were eager to try the affordable hack, with one person praising it as the "best, affordable and straightforward advice." For UK motorists battling the seasonal scourge of condensation, this proven method from a seasoned professional offers a quick, cheap, and effective solution to start the day with a clear view of the road ahead.
