Windshield Glass Cleaning: Exterior
WARNING: This page is about a different car, the 2019 Chevrolet Traverse. However, it is still accessible from the selected car via links, so may be relevant.
Clean the windshield with windshield cleaner, GM P/N 19287404 (18 oz.) or 19259280 (6 oz.) (Canadian P/N 88865156) or equivalent. The cleaner should not harm the paint finish or scratch the glass. The glass is clean when the water no longer beads, but sheets across the entire glass surface.
