A 9.45 in blade that pulls water, soap film and mineral haze off glass in a few passes. Run it down a shower screen while the cubicle is still warm and the door dries clear, which is the difference between a screen that stays sharp and one that slowly clouds over.
The width is chosen with care: broad enough to clear a full panel in three or four strokes, narrow enough to follow the frame of a bathroom mirror or a small window without catching the corners.
Works on shower doors, mirrors, tiled walls, windows and car windscreens.
Handheld and light, so it hangs by the shower and gets used daily.
Heavy-duty build for a tool that lives in a wet room.
Wipe the blade edge after each use and keep it out of grit, which is what blunts a squeegee.
