Failure to properly clean the windscreen can lead to water spots on the glass. Streaks and water spots occur when using a low-quality glass cleaner. Even products known as Windex do not always do the job, because many tend to over dry the windshield instead of letting the cleaner evaporate. To remove water spots from the windshield, as with other rebellious debris, use a different form of cleanser.
- Apply generously the foam to clean glasses on the surface of the windshield.
- Clean the windshield in an upward motion with the razor blade. Start on one side of the windshield, and work the other side using the razor blade and cleaning foam.
- Dry windshield with paper towels. You can clean the dry foam without worrying about scratching it.
