Should Defogger Spray Be Applied Inside or Outside?
1 Answers
Generally, it is applied inside. Waterproof Function of Defogger Spray: Raindrops falling on treated car glass will quickly form small water droplets under the action of the protective layer. When these droplets grow to a certain size, they will slide down the glass due to gravity, simultaneously carrying away dust on the glass, effectively cleaning it. When the vehicle speed reaches 50-60 km/h or above, the wind will cause the water droplets on the glass to roll upward automatically until they slide off the vehicle, creating a unique rainy scene. The glass surface remains dry after the water slides off, greatly ensuring driving safety. Anti-freeze Function of Defogger Spray: Treated glass has a protective layer, preventing snow or fog water from freezing solidly on the glass in winter. Snow accumulated on the glass can be easily removed, saving the hassle of clearing and waiting. Anti-oil Function of Defogger Spray: The atmosphere contains many gasoline molecules from exhaust emissions, which can form an oil film on the glass, causing glare during nighttime driving and affecting safety. Treated glass has an anti-oil function, making it difficult for an oil film to form. Any oil film that does form over time can be easily cleaned with a little detergent.
