How to Deal with Air Conditioner Water Corroding Car Paint?
2 Answers
If the corrosion is minor, you can go to a car beauty shop for polishing; if it's severe, you'll need to repaint, and the glass will also require polishing. Air conditioner water is highly corrosive, affecting not only the car's paint but also the front and rear windshield glass. Correct practices for protecting car paint: 1. Try to park the car in a garage: Avoid strong sunlight exposure and reduce rain exposure when parking. 2. Do not dry-wipe the car: Small gravel particles on the surface may scratch the paint, so always rinse with water. 3. Apply a glaze sealant when the car is newly purchased: Minimize polishing and focus more on waxing afterward. 4. Avoid random parking when parking outdoors: If you block the way or cause inconvenience, someone might scratch your car's paint.
To be honest, after driving for over a decade, I've developed a habit of checking for air conditioner water droplets on the car paint after parking. While this water appears clear, it actually contains acidity. Long-term accumulation can gradually corrode the paint surface, leading to fading or oxidative peeling. My advice is to rinse these droplets immediately with water - regular tap water is fine, but avoid high-pressure washers as excessive force can damage the paint. After rinsing, dry the area and apply neutral car wash soap to remove any residue. Prevention is even more crucial - try to avoid parking under trees or near air conditioner exhaust vents to minimize water accumulation. Regular waxing also helps create a protective layer; I've tried many products and found liquid wax works best when applied monthly. If you notice corrosion spots, don't attempt DIY fixes - visit professional auto detailing shops where they can use neutralizers for proper restoration. Consistent care maintains paint luster like new and saves significant repair costs later.
