The Real Problem Dirtying Windows Is Not Rain, But Invisible Particles Flying in the Air
Key Points
- It is thought that rain falling after cleaning windows leaves marks, but the main culprit is not the rain.
- Raindrops absorb microscopic particles flying in the atmosphere and present in the air we breathe.
- Drying raindrops leave the dust and dirt residues collected from the air on the glass surface.
It is a common belief that rain falling right after we have cleaned the windows of our house or car dirties the surfaces by leaving marks. However, rain itself is not the main culprit behind these marks on the windows.
In reality, the situation is closely related to microscopic particles that constantly fly in the air and are hidden in the air we breathe. As raindrops fall to the ground, they absorb these airborne pollutants, dust, and various residues, carrying them down.
When the raindrops hitting the windows dry, they leave these foreign substances behind on the glass surface, causing the formation of those annoying stains and marks. Therefore, rainwater merely acts as a carrier that transfers the airborne pollutants it contains onto our windows.
