  • Caring for Your Westeck Windows & Patio Doors
    To clean the glass, use a soft cloth or sponge with warm water and a mild soap. Dish soap is a cost-effective choice for outdoor window cleaning because it's gentle on glass and can effectively cut through dirt and grime.  Avoid any harsh chemicals or abrasive pads, they can scratch the surface or damage coatings. For best results, clean on a cloudy day to prevent streaks from sunlight drying the cleaner too fast. Wipe in a circular motion, then finish with a dry microfiber cloth for a clear, polished look.
