Use a back-and-forth fanning technique angling the squeegee to face horizontally with it being wide in the same direction as the top and bottom edges of the window. Sweep the water down and to the side to move it from the top of the window to the bottom edge. Carefully finish your last run on one of the lower window corners to create a streak-free finish.
The fanning technique takes significant practice, but all professional window cleaners use it to achieve a streak-free finish.
Clean with Abrasive Pads
Any high-traffic or very dirty window sections should be scrubbed using an abrasive pad before being squeegeed off. Use a 3M finishing pad for minor grime, use bronze wool for medium grime, and use a new 0000 steel wool pad for seriously tough grime. Scrub the dirty sections and then squeegee off the window like normal. Be careful to avoid using abrasive pads on tinted windows, and always use a fresh steel pad to prevent scratches caused by rust.
Clean the Frames
