How to Clean Car Windows Streak-Free

Updated July 20, 2017

Car windows should be kept clean so that the driver can see clearly at all times while the vehicle is being operated. Windows that are left streaked can cause safety issues and distort or block the driver's view. Cleaning the car windows should be done at the very end of the automobile cleaning process.

  1. Apply a small amount of the ammonia-free automotive glass cleaner directly on the cleaning cloth. For heavily soiled areas hold the cleaner 4 to 6 inches from the glass and spray directly on the difficult area.

  2. Wipe the window in either a side-to-side or up-and-down motion using the soft cleaning cloth.

  3. Rotate the cloth as needed to use a clean, dry area to scrub and absorb the remaining moisture from the window. Repeat the entire process as needed.

  4. Tip

    The car windows should be completely dried and cool to the touch. For best results, clean the windows out of direct sunlight. Heat from the sun will cause the cleaner to dry quickly, leaving the windows streaked. Microfiber cleaning cloths are designed to be highly absorbent.


    Ammonia-based window cleaners can cause damage to the interior dash of a car by causing it to dry out. Also, they are not safe to use on windows with after-market tint applied.
