Cleaning a glass channel can be very difficult, especially if a piece of tempered glass has broken. These pieces of tempered glass will stay embedded behind the lip of the run channel and scrape the glass as the window is wound up or down. Our Long Glass Channel Cleaner reaches behind that lip to remove even the most difficult embedded pieces of glass. The tool's rounded tip is designed to prevent damage to the weather stripping and approximately 43cm (17") long to reach deep inside the door.
