My neighbor's renovation caused a lot of overspray to land on my car. I used a clay bar with some glass cleaner, wetting it and gently rubbing back and forth.

One is to apply toothpaste on a damp cloth and repeatedly wipe the affected area—the abrasive components can remove the paint while protecting the glass.

For prevention, remember to roll up the windows when parking on the roadside, and wash the car promptly after rain to prevent paint spots from hardening. Keeping alcohol wipes on hand for emergency wiping is quite effective.
