Streaks from Windex or glass cleaners are almost always caused by using too much product, wiping in circles, or cleaning on a hot, sunny surface. To fix them, immediately buff the glass with a dry, clean microfiber cloth. If the streaks are stubborn, lightly re-wet the area and buff it until completely dry.
How to Avoid Streaks When Cleaning Your Windows
