As the UK plunges deeper into winter, drivers are facing the familiar and frustrating battle against foggy car windscreens. The combination of chilly air, damp weather, and our own body heat creates a perfect storm for condensation, both inside and outside the vehicle. While reaching for a cloth or frantically adjusting the blowers is the usual routine, a surprisingly simple household item could offer a more lasting solution.
The Viral Shaving Foam Hack Explained
An ingenious tip, shared on Instagram by user Griffith James, is gaining traction for its simplicity and effectiveness. The method involves applying a small amount of standard shaving foam to a microfibre cloth and buffing it onto the glass.
In a video demonstration posted in December 2025, Griffith showed how the technique not only cleans hard-to-reach water stains but also creates a water-repellent layer. "What this is going to do is this is going to stop the rain from sticking to it, while also stopping the windows from fogging up if you're doing this during the winter," he explained.
The hack works on both the exterior and interior surfaces of your car's windscreen, side windows, and wing mirrors, providing a dual defence against condensation. The crucial step, however, is to ensure the foam is rubbed in completely until the glass is perfectly clear, as any residue could dangerously impair visibility while driving.
Driver Reactions and Additional Anti-Fog Strategies
The social media post sparked enthusiastic responses from followers eager to try the trick for themselves. One commenter declared, "I'm running to try this right now," while another confirmed, "This is true, and works VERY well inside the car."
While the shaving foam method provides a clever preventative measure, tackling the root cause of moisture inside your car is equally important for a clear view. Here are some essential strategies:
Eliminate Moisture at the Source
Start by removing any wet items like coats, umbrellas, or floor mats. Check for and seal any leaks around door and window seals, and remember to take out any open water bottles that contribute to the humidity.
Ventilate and Dehumidify
Use your car's air conditioning alongside the heater, as the AC system actively dries the air. When it's safe, slightly cracking the windows allows damp air to escape. Avoid using the air recirculation setting for prolonged periods, as it traps moisture inside. For a longer-term solution, consider using silica gel dehumidifier bags or even silica-based cat litter in a sock placed in the footwell to absorb excess dampness.
Daily Habits for a Clearer Drive
Simple changes can make a big difference. Make a habit of wiping down windows with a dry, absorbent cloth or a dedicated window vacuum. You can also invest in a commercial anti-fog spray. Furthermore, try to clear snow and ice from your shoes before getting in the car to prevent introducing extra moisture.
With this combination of a clever hack using a common bathroom product and some proactive moisture management, drivers across the UK can look forward to clearer, safer journeys throughout the chilly and damp winter months.
