What's the best way to clean windows without streaks? As someone who's tested countless products over the years, I finally found the answer.
I'm thrilled to share this professional-grade homemade glass cleaner recipe, straight from my friend Manuel, a seasoned window washer with years of experience.
Store-bought cleaners often leave a hazy film, but this simple mix of vinegar, water, and dish soap delivers crystal-clear results every time. My windows now look invisible—truly the best I've ever used.
Before discovering this, I'd tried every commercial and DIY window cleaner out there—dozens of them. Nothing gave perfect, streak-free windows.
Then Manuel shared his go-to formula. He swore by it after years on the job, and after testing it myself, I agree: it's unbeatable.
The key? White vinegar cuts grease, water dilutes it, and a touch of dish soap ensures no residue. I whipped it up and cleaned my home's windows—stunning results on the first try.
- 50 cl (about 2 cups) hot water
- 5 cl (about 1/4 cup) white vinegar
- 1/2 teaspoon dish soap (like washing-up liquid)
- Bucket with handle
- Soft-bristled brush
- Garden hose
- Telescopic handle (optional but recommended)
- Spray bottle (optional)
1. Mix dish soap, white vinegar, and hot water in the bucket.
2. Attach the soft-bristled brush to the telescopic handle.
3. Dip the brush into the solution.
4. Scrub the exterior glass surfaces thoroughly.
5. Rinse immediately with the garden hose using clean water.
6. Ensure complete rinsing before the solution dries.
Voilà! Your windows will be spotless, transparent, and completely streak-free. Say goodbye to wads of paper towels and hello to professional clarity.
This is my go-to for both exterior and interior windows—simple, effective, and reliable after extensive personal testing.
Happy cleaning!
- For smaller jobs, transfer the mix to a spray bottle. But for multiple windows, the bucket-and-brush method saves significant time.
- Skip ladders with a telescopic handle—attach brushes or rollers easily. A spray gun helps with distant rinsing.
- Soft-bristle brushes are ideal; budget option: sponge mop.
- Finish with a squeegee for the last drops.
- Best for exteriors due to hose rinsing. For interiors: spray the mix, then rinse with plain water spray.
Key advice: Always rinse thoroughly before drying. Avoid direct sun to prevent quick evaporation.
