There’s nothing like sunlight pouring through clean windows—until you notice the streaks. Store-bought glass cleaners often leave behind residue, cost more than they should, and are packed with ingredients you can’t pronounce. The good news? You don’t need any of them. With just a few basics from your kitchen, you can make your streak-free window spray that works just as well, if not better.
Why Homemade Works
This isn’t about going full DIY for the sake of it. The homemade spray effectively cuts through grime and evaporates fast, leaving zero streaks. Plus, it’s cheaper and doesn’t fill your home with harsh fumes. Once you try it, you’ll wonder why you didn’t ditch the blue stuff sooner.
What You’ll Need
You only need three ingredients:
- 1 cup of white vinegar
- 1 cup of water
- 1 tablespoon of cornstarch
Yes, cornstarch. It sounds odd, but it makes a huge difference. It helps lift dirt and polish the glass, reducing streaks even more.
Optional: A few drops of essential oil (like lemon or lavender) if you want a nice scent.
How to Make the Spray
- Combine the vinegar, water, and cornstarch in a spray bottle.
- Shake well before each use—the cornstarch settles fast.
- Spray on your window or mirror and wipe with a lint-free cloth or crumpled newspaper.
Tips for Best Results
- Avoid cleaning windows when the sun is hitting them directly. It dries the spray too fast and can cause streaks.
- Use a clean, dry cloth every time. Leftover residue on rags is the number one reason for streaks.
- For filthy windows, do a first pass with plain water or soapy water to remove gunk, then follow up with the spray.
You don’t need a shelf full of fancy cleaners to get windows that shine. With this easy homemade spray, you’ll get clear, streak-free results using ingredients you already have. It’s quick, it’s cheap, and it works. Give it a shot—and enjoy the view.
