What Causes the Dense Tiny Dots on the Car's Front Windshield?

[LaHarley]

Dense tiny dots on the car's front windshield are caused by asphalt, bird droppings, or iron particles. Method to Remove Asphalt: If the small black dots on the car paint are asphalt, you can use a tar remover to clean them. Simply spray the tar remover on the black dots and wipe repeatedly with a damp cloth. Method to Remove Bird Droppings: If the small black dots are caused by bird droppings or other impurities, you can spray car wash soap or glass cleaner on the dots. Once the dots soften, they can be easily cleaned off. Note that the car wash soap and cleaner must be neutral to avoid corroding the car paint. Method to Remove Iron Particles: For small black dots caused by iron particles, you can purchase a professional iron particle remover. Spray it on the black dots to dissolve them, then wipe them off with a cloth.
