How to Remove Rain Repellent?

To remove rain repellent, you can evenly spray carburetor cleaner or gasoline on the glass, wipe it off, and then rinse with clean water. The main component of rain repellent is a nano organic active agent, which forms a nano protective film on the glass surface after application. The water repellency is achieved through physical properties, without any chemical reaction, corrosion, or pungent odor. The method for using rain repellent is as follows: 1. Clean the windshield thoroughly with a towel; 2. Shake the rain repellent gently and spray it evenly on the car glass; 3. Use a clean, dry sponge to evenly spread the rain repellent on the car glass; 4. After the glass surface dries, use a cotton cloth or tissue to wipe the glass surface until it becomes shiny.
I often teach car owners how to remove rain repellent coatings because although the film is waterproof, it may affect wiper performance or visibility. It's recommended to first spray the glass thoroughly with a professional automotive glass cleaner, wait a few minutes to let it soften the coating, then scrub repeatedly in circular motions using a microfiber cloth. Repeat this process at least two or three times, rinsing clean each time. Test on a small corner first to ensure no glass damage occurs. If results are poor, switch to using alcohol or vinegar sprayed on the cloth for targeted wiping - these are strong degreasers but require gentle handling. After removal, check wiper operation to avoid driving hazards. Avoid doing this process in direct sunlight as it may leave streaks. Once completed, either reapply a high-quality new rain repellent or simply stop using hydrophobic treatments altogether - this saves money and is safer.
