Thank you for sharing experience with us. I’m so sorry to hear you didn’t receive the streak-free shine we’d hope for. To achieve sparkling results, it’s important to choose the right towel. Low lint, untreated paper towel or a soft lint-free cloth will work best to achieve a beautiful streak-free shine. As we’re always working to provide products you can count on, we’d like to restore your confidence in Windex® and help make this up to you. So we can, give us a call at 1-800-558-5252, Monday-Friday between 8 AM-5 PM CT. Be sure to mention this reference number: 22175712. Talk soon! – Brooklyn, SC Johnson Consumer Care
