Raindrops Carry Tiny Electrical Charges That Eat Through Your Car’s Fresh Paint Job Research published in Nature has revealed a surprising culprit behind water's destructive power: electrically charged raindrops.
For years, we've been told that rain causes corrosion due to its high salt content or acidic nature. However, this explanation is only part of the story.
Scientists at the Max Planck Institute for Polymer Research discovered that even small amounts of electrical charge in raindrops can break down protective coatings and lead to metal corrosion.
