Understanding Acid Rain and Its Effects on Glass

What Is Acid Rain?
Acid rain occurs when sulfur dioxide (SO2) and nitrogen oxides (NOx) mix with water vapor in the atmosphere, creating acidic precipitation. This environmental phenomenon is primarily caused by industrial emissions, vehicle exhaust, and natural events like volcanic eruptions.
How Does Acid Rain Damage Windows?
When acid rain dries on glass surfaces, it leaves behind mineral deposits that can etch the glass over time. These spots not only mar the appearance of windows but can also lead to permanent damage if not addressed promptly.
