This man is showing us how to get a streak-free windshield every time. He starts by spraying a glass cleaner onto the inside of the windshield. He then takes a microfiber cloth and wipes the cleaner off in a circular motion. He then takes a squeegee and wipes the windshield in a vertical motion, starting from the top and working his way down. He then takes a dry microfiber cloth and wipes the windshield in a horizontal motion, making sure to get all the streaks off. Finally, he takes a clean microfiber cloth and wipes the windshield in a circular motion to make sure it is completely streak-free. With this method, you can be sure to have a streak-free windshield every time.
