Does Air Conditioner Dripping Water on the Car Matter?
2 Answers
Air conditioner dripping water on the car has no impact. The water from air conditioner drips is mainly the water vapor in the air, commonly known as condensate water. Its chemical indicators, such as pH, are consistent with the environmental air and are not corrosive, so it will not harm the car body or the interior. Below are the related details: 1. Leaves stains: If the car is parked under the outdoor unit of an air conditioner, it may get dripped on by the air conditioner water. Although it won't cause damage to the car, after long-term dripping, stains may be left once the water dries. At this time, a wet towel with toothpaste can be used for wiping. 2. No harm to the vehicle: Normally, air conditioners not only leak water from the outdoor unit when heating, but also produce condensate water from the indoor unit's evaporator when cooling. The condensate water will flow out through a pipe, which is the same water as from the outdoor unit's condensate, and it will not damage the car glass or paint.
My car has been parked under an outdoor air conditioning unit for years, and I've observed it for over three years. The condensation water from the AC itself isn't a major issue; its main component is just condensed water, which doesn't corrode car paint like tree sap does. However, if it drips on the roof for a long time, it leaves unsightly water stains, especially on white car bodies—under the sun, these turn into yellowish, map-like spots. Once, after a two-week business trip, I found water stains on the hood that even a high-pressure water gun couldn't remove, and I ended up spending 200 yuan on polishing to fix it. Now, I always look up to check for outdoor AC units before parking. If I can't avoid it, I wash the car every three days. Rainy days aren't a problem because the rainwater washes away the stains.
