How to Make Blurry Car Windows Clear Again?
2 Answers
Methods to make blurry car windows clear again are as follows: Apply Anti-Fog Spray: When using an anti-fog spray, the car owner only needs to evenly spray it on the glass surface and then wipe it clean with a dry towel. After wiping, a protective film will remain on the glass surface, altering the surface tension of water molecules and causing fog droplets to coalesce into larger droplets, thereby not obstructing the view. This method is also suitable for other car windows, especially the exterior rearview mirrors. DIY Anti-Fog Solution with Dish Soap: Mix dish soap and water in a 1:6 ratio and spray it on the windows before driving. The effect is comparable to that of an anti-fog spray, though it lasts slightly shorter. Using soapy water, hand soap, or laundry detergent as substitutes yields less effective results than dish soap.
I get a bit nervous when the car glass gets blurry, having driven for almost twenty years, I know how dangerous poor visibility can be. First, check if the issue is outside or inside: for external oil film or insect residue, spray glass cleaner all over the glass, wait ten seconds to let the dirt soften, then wipe it clean with a microfiber cloth—avoid rough materials to prevent scratches. If the wipers are old and don’t clean properly, just replace them for an instant fix. For internal fogging, turn on the air conditioning’s defog mode at maximum fan speed or press the front window defrost button to quickly dehumidify—it’ll clear up in a minute or two. If humidity is high, place some desiccant or bamboo charcoal bags inside the car when parked to reduce fogging sources. I also regularly apply anti-fog spray on the inner side of the glass for lasting clarity—it’s simple and safety comes first. Always check the glass cleanliness before long trips—don’t skip this small habit to prevent accidents. This is important and worth reminding all fellow drivers.
