Owning a car is awesome - except for when you have to clean it. I learned a very difficult lesson about hard water stains on a dark colored car. I thought that I was doing the smart thing by parking my car directly beside the sprinklers at my house. (I live on a long dirt road that constantly gets my car dusty and I thought that the water would rinse it off and keep it looking nice.) What I didn't realize is that my hard water would make my car look terrible. My blog contains the information you need to remove hard water stains from your vehicle. Hopefully, my trial and error will help save you some time removing the stains from your car.
