Acid rain is defined as “rainfall made sufficiently acidic by atmospheric pollution.” Can it harm your vehicle, internal parts, and fluids? Rain that contains more elements and pollutants than normal water can cause paint damage if left untreated.
Where does acidic rain occur? Well, in America, it can happen in a lot of places. Water.usgs says:
The areas of greatest acidity (lowest pH values) are located in the Northeastern United States. This pattern of high acidity is caused by the large number of cities, the dense population, and the concentration of power and industrial plants in the Northeast. In addition, the prevailing wind direction brings storms and pollution to the Northeast from the Midwest, and dust from the soil and rocks in the Northeastern United States is less likely to neutralize acidity in the rain.
So what’s the best way to deal with acid rain if you do happen to need to drive in those areas? First, wash your car. There’s really not a way to tell if your car has been subjected to acidic rain, so wash your car regularly to avoid paint damage. Generally, acid rain won’t get inside your vehicle, so a regular wash should keep you covered!
