How to Use a Squeegee on Windows Properly
The professional way to hold and move a squeegee: the grip, the 45 degree angle, and the three turns that clear a pane in seconds.
The squeegee is the most important tool in window cleaning, and it is the one almost everyone uses wrong. Held properly, it clears a pane of water in seconds and leaves nothing behind. Held wrong, it pushes water around, skips, and streaks. After twenty five years I can teach you the difference in one read.
Hold it the right way
Grip the handle loosely, like a paintbrush, not like a hammer. A tight, tense grip locks your wrist and kills the smooth movement you need. Your wrist does the work, not your whole arm. The looser your grip, the more control you have, which feels backwards until you try it.
The angle is everything
Hold the squeegee at roughly a forty five degree angle to the glass. Too flat and it skips and leaves lines. Too upright and it pushes a wave of water in front of it that spills where you do not want it. At forty five degrees the rubber shaves the water off cleanly, which is exactly what you want. This single detail fixes most beginner problems on its own.
Overlap every stroke
Each stroke should slightly overlap the clean, dry glass you just cleared. Leave a gap and you leave a line of water that dries into a streak. Overlapping by an inch or so means the whole pane gets cleared with no missed strips.
Wipe the blade after every stroke
This is the habit that separates clean from professional. After each pass, wipe the rubber with a clean 100% cotton towelling rag. If you do not, you drag the dirty water you just collected straight back across the glass on the next stroke. A wet, dirty blade is the hidden cause of half the streaks people blame on their squeegee.
The three turns
A professional does not lift the squeegee off the glass for a whole pane. They link three turns into one flowing movement: side to side, top to bottom, and the turn with a twist, which we call the J tune. Side to side and top to bottom are the foundation and you can learn them in an afternoon. The turn with a twist is what lets you clear an entire window in one continuous motion, and it is the technique that takes real practice to master. It is worth every minute.
Keep the rubber fresh
Even perfect technique cannot beat a worn rubber. The rubber is the part that actually touches the glass, and once its edge rounds off it streaks no matter what you do. A replacement costs a dollar or two. Change it far more often than you think you need to. It is the cheapest fix in the whole trade.
The common mistakes
Gripping too tight. Holding the blade too flat or too upright. Skipping the wipe between strokes. Leaving gaps instead of overlapping. Fighting a worn rubber. Fix those five and your glass transforms, with the tools you already own.
Feel it in your hands
You can read this twice and still not have it, because a squeegee stroke is a physical skill. Nothing teaches your hands the forty five degree angle like doing it with guidance.

Frequently asked questions
What angle should you hold a squeegee at?
Around forty five degrees to the glass. Too flat and it skips and leaves lines. Too upright and it pushes a wave of water in front of it. At forty five degrees the rubber shaves the water off cleanly, which is what gives you a streak free result.
Why does my squeegee leave streaks?
The three usual causes are a worn rubber, not wiping the blade between strokes so you drag dirty water back across the glass, and holding the squeegee at the wrong angle. Fix all three: fit a fresh rubber, wipe the blade after every pass with a cotton rag, and hold it at about forty five degrees.
How do professionals move the squeegee so smoothly?
They link three turns into one continuous motion, side to side, top to bottom, and the turn with a twist, without lifting the blade off the glass. A loose grip and a fresh rubber make it possible. It looks effortless because it is practised, and it is very learnable.
