I've been driving for over a decade, and this kind of air conditioning water stain is all too common. It's mainly white circles left by dried minerals in the condensate water. At first, you can wipe it off with a damp cloth, but it becomes harder to deal with over time. Here's a home remedy for you: buy a bottle of white vinegar from the supermarket, mix it with warm water in a 1:1 ratio, soak a kitchen paper towel in it, and directly apply it to the spots for half an hour. Then gently scrub with a nano sponge and rinse clean with glass cleaner. If it's particularly stubborn, take it to a car repair shop and have them use that glass cleaning paste with abrasive agents—it'll cost you about a hundred yuan to get it done. The key is to deal with it early. Last year, I didn't take care of it in time on my car, and now when it rains, the wipers leave water marks. Oh, and after cleaning, it's best to apply a coating to the glass—it can prevent water stains for about three months.
As a frequent visitor to car detailing shops, dealing with air conditioning watermarks requires a two-step approach. First, address the surface: spray professional glass cleaner onto a microfiber cloth and wipe the watermarked area in circular motions. Avoid doing this after prolonged sun exposure, as high temperatures can make watermarks more stubborn. For deep cleaning, a citric acid solution is recommended—mix 2 tablespoons with 500ml of warm water and gently scrub the glass crevices with a soft-bristle brush, as these areas are most prone to water stain buildup. After treatment, be sure to rinse with clean water three times to prevent residue from corroding the wiper blades. Before the rainy season, it's advisable to perform a monthly glass hydrophobic treatment to prevent water droplets from clinging and leaving marks. If DIY efforts fall short, professional ceramic coating can provide up to six months of protection.
