<bot>: The best way to clean windows without streaks is to mix equal parts of white vinegar and water in a spray bottle, use a microfiber or lint-free cloth, spray the solution onto the windows, and then wipe them in a circular motion. Additionally, it is important to regularly dust the windows to prevent buildup of residue which can cause streaks when cleaning.
