What can be sprayed on glass to prevent water from sticking?

You can use a specialized water repellent by applying it to the glass, which will cause rainwater to flow off naturally, maintaining clear visibility. Additionally, alternatives such as soap, dishwashing liquid, or candles can be used. Taking dishwashing liquid as an example, first clean the glass with a dry cloth, then pour the dishwashing liquid onto the dry cloth and wipe every corner of the glass. It's important to note that the entire process should avoid water contact. Wipe with the dry cloth until no traces of dishwashing liquid are visible on the glass. This method not only adds fragrance and removes odors but also ensures clear glass during rainy days. If the vehicle is equipped with a rearview mirror heating function, simply turn it on to eliminate water droplets on the mirror. The rearview mirror heating and rear windshield heating typically share the same button. Another option is to apply a glass coating. Glass coating prevents water droplets from forming irregular films that obstruct vision, ensuring the driver's view remains unaffected by rain films. It significantly enhances visibility, improving driving comfort and safety in rainy conditions. It also makes it easier to clean dust, oil stains, and insect residues from the glass surface, while filling in microscopic cracks. Furthermore, it prevents the formation of oil films and dirt on the glass, keeping it more transparent and clear.
I always find it annoying when the car windows get blurry on rainy days, and I've tried many water-repellent sprays. The most commonly used one is the glass water repellent, which forms a transparent hydrophobic layer on the glass surface, causing rainwater to bead up and roll off. I bought a spray with a nano-silica formula, and the application is very simple: first, thoroughly clean the glass, dry it, shake the spray well, spray it evenly from 20 cm away, wait three minutes for it to form a film, and finally wipe it evenly with a microfiber cloth. The effect lasts for about three to four weeks, making it especially suitable for side windows and rearview mirrors. When driving at high speeds, the rainwater slides off automatically, reducing the need to constantly use the wipers. This kind of product can be bought online for just a few dozen yuan, but be careful not to buy low-quality ones with a strong, irritating odor.
