There’s nothing more frustrating than spending your afternoon cleaning windows—only to step back and see streaks staring back at you. The truth is, streaks aren’t caused by dirty windows. They’re caused by bad technique and the wrong tools.
If you’ve struggled with smears, haze, or glass that somehow looks worse after you’ve cleaned it, this post is for you. Here’s how to get sparkling, streak-free windows every time.
What Causes Window Streaks?
Before we get into the solution, let’s look at the problem:
- Wrong cleaners – Some glass cleaners leave behind residue or evaporate too quickly, especially on hot days.
- Dirty tools – Reusing a filthy rag or murky water just spreads dirt around.
- Poor drying methods – Paper towels leave lint, and wiping in circles spreads cleaner unevenly.
What You’ll Need:
Here’s your no-streak window cleaning kit:
- A good squeegee (like Unger or Ettore brands)
- Microfiber cloths (not paper towels!)
- A bucket with warm water
- Scrubber or sponge
- A streak-free cleaner — You can go with a commercial product like Sprayway, or make your own:

- 1/2 cup white vinegar
- 1 drop of dish soap (optional)
- Mix in a spray bottle and shake gently
Step-by-Step: How to Clean Windows Without Streaks
- Dust the Window Frame First
Wipe down the sill and frame with a dry cloth to prevent dirt from dripping onto your clean glass later. - Apply Your Cleaner
Spray your cleaner generously on the window or dip your scrubber in your solution and apply it evenly. - Squeegee Method: Top to Bottom
Start at the top corner and pull the squeegee in one smooth motion downward. Wipe the rubber blade with a cloth after each stroke. - Dry the Edges
Use a clean, dry microfiber cloth to catch any drips or streaks at the edges or corners. - Check for Missed Spots
If necessary, re-wipe any trouble spots with a slightly damp microfiber cloth and dry it immediately.
Pro Tips for Perfect Results
- Avoid direct sunlight – It dries the cleaner too fast, causing streaks. Cloudy days are best.
- Use distilled water – If your tap water is hard (high in minerals), distilled water prevents white residue.
- Change out cloths and water often – Don’t spread dirt from one window to the next.
- Use the “Z” method if needed – For wide windows, use a sideways “Z” squeegee motion to cover more area without overlap.
Final Thoughts
Streak-free windows are totally achievable—and they make a huge difference in how your home looks and feels. With the right tools, a little patience, and the techniques above, your windows will shine like they were professionally cleaned.
