Streaks are the most common window cleaning frustration. The secret professionals use isn't an expensive spray: it's technique. With a good squeegee, a microfiber cloth and the right method, you can get streak-free windows, mirrors and shower glass in minutes.
What you need
- A squeegee with a soft, straight rubber blade
- A scrubber or sponge to wash the glass
- A bucket of warm water with a few drops of dish soap, or a streak-free glass cleaner
- Two microfiber cleaning cloths: one for edges, one for final polishing
The squeegee method, step by step
- Clean on a cloudy day or in the shade. Direct sun dries the solution too fast and causes streaks.
- Wash the glass with the scrubber, loosening dirt from corners and frames.
- Dry one inch of the edge along the top with a cloth so the squeegee has a dry starting point.
- Pull the squeegee across or down the glass in one smooth stroke, overlapping each stroke by about an inch.
- Wipe the blade with a cloth after every stroke. A dirty blade is the main cause of streaks.
- Finish the edges with a dry microfiber cloth.
Common mistakes to avoid
- Using paper towels, which leave lint.
- Using too much product: more soap means more residue.
- Using a worn or nicked rubber blade. Replace it when it stops gliding smoothly.
Shower glass and mirrors
Squeegee shower glass after every shower to stop water spots and soap scum from building up. For mirrors, spray a microfiber cloth instead of the mirror to avoid drips behind the frame.
When to use a window vacuum or window robot
A cordless window vacuum sucks up dirty water as you squeegee, so there are no drips on sills or floors. It's ideal for large windows, glass doors and tiled walls. A window cleaning robot automatically cleans big or hard-to-reach panes while you do something else.
