I’ve told a couple people about how I clean my taller windows and they’re surprised and pleased. I figured I’d put it out into the world.
Use your Swiffer Wet Jet floor mop as a window cleaner. Simply spray the solution onto the windows, scrub with the pad, and wipe with the attached squeegee. No streaks, reaches high up, easy to do when you figure out the angle.
You can use a different solution, I suppose, but I just use the floor mop stuff and have no issues.
