Squeegee Windows in an S, Not Up and Down

The Problem

The instinctive squeegee stroke is up-and-down lanes, lifting the blade between passes — and every lift-and-restart leaves a wet line that dries into a streak. It's also slow: each lane overlaps the last, and the blade spends half its time off the glass.

The Technique

1. Wet the window with your scrubber as usual.
2. Start the squeegee in a top corner — top left, say.
3. Pull straight across the top, keeping the leading edge of the blade tucked into the top corner as you go, so no dry strip survives above the stroke.
4. Without lifting the blade, sweep down and pull back across the other way.
5. Keep snaking — corner to corner, down and across — in one continuous S until you run off the bottom of the glass.

Because the blade never leaves the glass mid-window, there are no restart lines — the water gets carried down and off in one connected pass.
