Double-hung windows are awesome for ventilation, but cleaning them can feel like a headache. Here’s the secret: you don’t need ladders, and you don’t need fancy sprays. With
a basic squeegee and a quick tilt of the frame, you can get streak-free glass from inside your house.
1. Get the Right Setup
Skip the paper towels—they just smear dust around. Grab these basic tools:
-
A 10 or 12-inch squeegee
-
Dish soap & warm water (just a few drops of Dawn creates the ultimate slide)
-
A sponge or washer sleeve
-
Two microfiber cloths (one wet for frames, one totally dry for edges)
2. Master the Tilt Mechanism
The magic of double-hung windows is that both sashes tilt inward so you can clean the outside glass without stepping outdoors.
-
Bottom Sash First: Unlock the window, raise the bottom frame up 2 inches, pull the top side latches inward, and tilt the glass toward you.
-
Top Sash Second: Lower the top frame a few inches, pull its latches, and tilt it down over the bottom frame.
-
Now, both exterior panes are lying flat, right in front of you.
3. Scrub, Squeegee, Detail
-
Prep the Sill: Vacuum or wipe the tracks first so dry dirt doesn’t turn into mud when water hits it.
-
Scrub: Wet the pane completely with soapy water to loosen dust and pollen.
-
Pull: Drag your squeegee straight down from top to bottom, overlapping each stroke slightly. Wipe the rubber blade dry after every single pass.
-
Detail: Wrap your dry microfiber cloth over your finger and trace the outer edges to catch lingering water droplets.
3 Quick Rules for Longer-Lasting Shine
-
Never clean in direct sunlight: The sun bakes soap onto the glass before you can squeegee it off, causing streaks.
-
Wash your screens: Rain pushes dirty screen dust back onto clean glass. Rinse screens once a season.
-
Keep tracks clear: Clean sills prevent gunk from splashing back onto the bottom pane during heavy rain.
