Why Self-Cleaning Windows Stay Clear in Rain

Why Self-Cleaning Windows Stay Clear in Rain

自清洁玻璃为何遇雨更干净

  1. Special coatings on glass break down dirt using sunlight.
  2. Rainwater spreads evenly instead of beading up.
  3. Dirt sticks weakly, so water washes it away easily.
  4. Titanium dioxide in the coating acts like a sun-powered cleaner.
  5. No soap or scrubbing is needed for routine cleaning.
  6. These windows last longer and need less maintenance.
  7. They work best in sunny, rainy climates together.
  8. Clean views come from science—not just wiping.
