The most efficient way to clean a window is to use a microfiber cloth or squeegee, and a window cleaner solution. Start at the top left corner of the window and move horizontally to the right. When you reach the end of the window, wipe the squeegee with the cloth, then move downwards to the next line. Repeat this process until the window is cleaned.
