Does Rain Make Windows Dirty? The Truth Behind This Common Myth
We’ve all heard it before: “Why clean my windows? It’s just going to rain and make them dirty again!” But here’s the truth—rain itself doesn’t make windows dirty. It’s actually the dust, pollen, and pollution already on the glass that causes spots and streaks.
At Epic Exterior Services, we decided to put this to the test!
Putting Rain to the Test: The TDS Experiment
To find out if rain really affects window cleanliness, we collected a rainwater sample and measured its TDS (Total Dissolved Solids) level.
🔬 What is TDS?
TDS stands for Total Dissolved Solids, which measures the amount of minerals, salts, and other particles in water. The higher the TDS, the more impurities are present.
✅ Our rainwater sample measured at 5 TDS.
💦 For reference, we clean windows using purified water with a TDS between 0-6.
This means that rainwater is nearly as pure as the water we use for professional window cleaning!
So Why Do Windows Look Dirty After Rain?
The issue isn’t the rain itself—it’s what’s already on your windows before it rains.
Here’s what happens:
If your windows have dust, pollen, or pollution buildup, rainwater mixes with these contaminants and leaves visible spots and streaks as it dries.
If your windows are professionally cleaned, rainwater rolls off without leaving marks, keeping your view crystal clear.
The Solution? Regular Window Cleaning!
Keeping up with regular professional window cleaning ensures that rain won’t leave behind spots or streaks. Plus, it extends the life of your glass by preventing buildup that can cause long-term damage.
