I have found especially since I have had an aqua dapter I can minimize the dripping from top frame. I am sure many do this but for those that don't it works for me. Once you have cleaned all frame stop water flow either with your tap or just kinck the hose, shake excess water off brush then run over top frame, shake water off and run over again down to where the frame meets window. Then rinse window as you normally would I find I do this on most windows now and often do this instead of doing all frames then going back to first window after it has stopped dripping. Not had any trouble or marks from doing this.
