As January's chill sets in, drivers across the UK are facing the familiar and frustrating battle with condensation on their car windscreens. This common winter nuisance can obscure vision and make morning commutes a hazardous chore. However, motoring experts at the RAC (Royal Automobile Club) have endorsed a surprisingly simple household solution that could prevent the problem altogether.
The Simple Household Item That Fights Fog
The RAC advises that a common can of shaving foam could be the key to a clear view. This unconventional hack, which has been shared widely by motorists on platforms like Reddit, involves applying the foam to the interior glass. One Dutch driver highlighted its value, noting that fines for driving with fogged windows are high in the Netherlands and that older cars are particularly prone to the issue.
Social media users have expressed their enthusiasm for the method. "I've used it on my bathroom mirror for almost 10 years. Never did I think to use it on my car windshield," remarked one. Another grateful user responded, "You, my good sir, have made my life a little easier." The technique is also reportedly a long-standing secret among motorcycle racers to keep their goggles from fogging over.
How to Apply the RAC-Approved Method Correctly
While the RAC validates the effectiveness of shaving foam, they stress that correct application is crucial for road safety. The process must not compromise visibility. According to official guidance on the RAC website, drivers should take a clean towel and place a small dollop of shaving foam onto it.
This should be wiped thinly and evenly across the entire interior surface of the windscreen. A second clean, dry towel is then used to wipe off the foam completely. The glass must be buffed until it is entirely clear and free of any streaks or residue that could obstruct the driver's view.
Important Considerations for Lasting Results
The protective barrier created by the shaving foam is not permanent. The RAC notes that it will need to be reapplied regularly to continue working effectively throughout the winter season. For those seeking an alternative, the organisation also suggests demister pads, which are available to purchase from the RAC Shop.
This simple, low-cost hack promises to significantly cut down the time spent clearing windows on cold mornings. By following the RAC's specific guidelines, drivers can tackle condensation proactively, ensuring safer journeys during the colder months. The advice was highlighted in an article dated 15 January 2026, by journalist Katie-Ann Gupwell.
