Window fog, one of car ownership’s nuisances, brings with it myths about shortcuts, remedies, and prevention. People have all sorts of ideas about what works best, and the recommendations usually include something other than a product specifically designed for that purpose.
YouTuber ChrisFix set out to test five different remedies to show us how to keep our glass fog-free. The experiment included a store-bought anti-fog product up against four common household items. Each one was applied to the interior side of the car’s window as a preventative.
First, he reviews how we get fog on the inside of our car windows. Cold air outside clashes with moist, warmer air on the inside, causing condensation. Your heater, breath, and other things can cause the windows and windshield to haze over. Treating the inside portion of the glass can help prevent the foggy effect from forming.
Outside fog that forms from humidity and your A/C is a different type, and not covered in this particular vid by ChrisFix. In this test, one car window was partitioned off into five sections to test five cures. Each item was applied to the glass’s surface and wiped down to remove any excess. A hot pot of water was used to create steamy windows.
