How to Remove Rainwater from Side Windows
2 Answers
Removing rainwater from side windows can be done using toothpaste, soap, or a water repellent. Additional Information: 1. Toothpaste and Soap: Toothpaste and soap are very practical and effective methods. On rainy days, evenly apply toothpaste or soap to the side windows of the car. Wait for a while until the applied soap hardens, then wipe it clean with a towel. At this point, a wax layer will form on the glass surface, which has excellent water-repellent properties and can effectively prevent fogging or water droplets on the rearview mirror from causing blurred vision. Additionally, keeping soap in the car can also help freshen the air and eliminate odors. 2. Water Repellent: Purchase and use a dedicated water repellent. Currently, water repellents on the market generally come in two forms: spray and application. Simply spray or apply the water repellent evenly on the rearview mirror. A protective film will form on the surface of the rearview mirror, which also has excellent hydrophobic properties. This can effectively prevent fogging or water droplets on the rearview mirror, ensuring clear visibility.
As a long-time driving enthusiast, my most common method for dealing with rainwater on side windows is using automotive glass water repellent. It's like spraying on a transparent coating that causes water droplets to quickly slide off without blurring. The operation is very simple: first clean the glass surface to ensure there's no grease, then spray evenly and wait a few minutes before wiping it dry. The effect lasts for several weeks. If it suddenly rains and I haven't applied the repellent, I usually turn on the air conditioning to defog mode, directing the airflow at the windows to reduce humidity, or quickly lower and raise the window to scrape off water droplets, allowing me to handle it safely without stopping. I always keep a microfiber cloth in the car for manual wiping when needed, but I'm careful not to do it while driving. Regularly checking the rubber seals on the windows to prevent leaks and ensuring the drainage channels are clear can significantly reduce rainwater issues with proper maintenance.
