So, I park my car outside. And the damn sprinkler system always sprays on the side of my car. The water has a fairly high mineral content. When the water dries (almost instantly, here in the desert), mineral deposits are left on the paint and on the window.
Simply washing the car with soap and water isn’t getting the deposits off. Even using a green scrub pad on the windows doesn’t seem to work. And I don’t want to scrub the paint off the side of the car.
Any suggestions on how to remove this buildup without ruining the finish?
