Why Make Your Own Window Cleaner?
Homemade window cleaners offer several advantages over store-bought options:

- Customizable Performance: Adjust your recipe for streak-free cleaning, extra grease removal, or a preferred fragrance.

Essential Ingredients and Recommended Tools
Most homemade window cleaners use a combination of simple, safe household ingredients. Here’s what you’ll need:
| Ingredient | Purpose |
|---|---|
| Distilled Water | Reduces streaks and mineral deposits, particularly in hard water areas |
| Isopropyl Alcohol (Rubbing Alcohol) | Fast-evaporating solvent, disinfects and minimizes streaks |
| White Vinegar | Breaks down grime and mineral deposits, non-toxic |
| Mild Dish Soap | Degreases and adds light fragrance |
| Essential Oils (optional) | Personalize fragrance; use sparingly to prevent streaks |
| Cornstarch (optional) | Mild abrasive for built-up dirt, especially outdoor windows |
Basic tools:
- Empty spray bottle (glass or plastic)
- Funnel (for easy mixing)
- Measuring cups and spoons
- Soft bristle scrub brush or microfiber cloth
- Extension pole (for high or outdoor windows)
- Bucket (for larger-scale jobs)
Best Homemade Window Cleaner Recipes
There is no single ‘perfect’ window cleaner formula—what works best may depend on your home’s needs, local water quality, and personal preference. Below are tried-and-true recipes you can mix and match for optimal results:
Classic Alcohol-Based Window Cleaner
- 1 cup distilled water
- 1 cup isopropyl (rubbing) alcohol (70%)
This mix delivers fast evaporation and minimal streaks—ideal for quick indoor touch-ups.
Vinegar-Based Window Cleaner
- 2 cups distilled water
- 1/4 cup white vinegar
The acetic acid in vinegar breaks down tough dirt and leaves glass clear.
Lighter Odor, Lighter Duty Formula
- 2 cups distilled water
- 1/4 cup isopropyl alcohol
- 1/4 cup white vinegar
A balanced solution for regular maintenance with a milder scent.
Grease-Cutting & Fragrance Boost
- Add 1/2 teaspoon or 5–10 drops of mild dish soap to any of the above recipes
- Add up to 5 drops of essential oil for custom scent
Dish soap is a powerful degreaser; essential oils such as lemon, lavender, or peppermint can boost freshness. Avoid excess oil to prevent residue.
Heavy-Duty Scrubbing Formula
- Add 1 tablespoon cornstarch to any of the above recipes
Cornstarch provides gentle abrasion for removing stubborn grime—especially helpful for exterior windows. Remember to rinse thoroughly after cleaning.

How to Mix and Use Homemade Window Cleaner
Mixing Instructions
- Choose your recipe and assemble ingredients.
- Use a funnel to pour ingredients directly into a clean, empty spray bottle.
- Seal and shake the bottle gently to combine.
- Label your bottle with a permanent marker or adhesive label (include a date for best tracking).
Always use newly purchased bottles if possible, or wash reused bottles thoroughly with soap and water. Never mix chemicals such as bleach and vinegar, as this can produce dangerous gases.
Application Step-by-Step
- Clear away dust or debris from window surfaces.
- Spray cleaner directly onto glass, one pane at a time.
- Wipe with a lint-free cloth, microfiber towel, or newspaper for streak-free shine. Newspaper can be composted after use and doesn’t leave lint.
- Use extension poles or scrub brushes for high or outdoor windows.
- For formulas containing cornstarch or extra soap, rinse the window with plain water after cleaning to avoid residue.
Optional: For extra dirty areas, let the cleaning solution sit for 30 seconds before wiping.
Expert Window Cleaning Tips for Streak-Free Glass
- Distilled Water eliminates streaks caused by mineral content found in tap water, especially in hard water regions.
- Quick Evaporation of alcohol-based solutions helps prevent water spots by drying faster.
- Always clean windows on a cloudy day or during cool mornings to avoid rapid evaporation, which can leave streaks behind.
- Label and date your cleaner bottles to avoid confusion and ensure freshness.
- Never use vinegar-based cleaners on marble, stone, or sensitive surfaces—acid can damage these materials.
- Switch to newspaper instead of paper towels for a lint-free shine, and compost after use to reduce waste.

Frequently Asked Questions (FAQs)
Q: Can I reuse old spray bottles for homemade cleaner?
A: It’s best to use new bottles, since residual chemicals in old containers can cause unpleasant reactions—especially if they previously held bleach or ammonia. If reusing, thoroughly wash with soap and water, and allow to dry before adding your cleaner.
Q: Will homemade window cleaner leave streaks?
A: If made with distilled water and the right proportions, DIY cleaners usually leave fewer streaks than many commercial formulas. Using alcohol speeds evaporation for a streak-free finish, and wiping with microfiber or newspaper can further minimize streaks.
Q: Why does vinegar work so well on glass?
A: Vinegar contains acetic acid, which dissolves mineral deposits and breaks down grime without scratching glass. It’s a non-toxic, safe choice for most households.
Q: Is it safe to use homemade window cleaner around pets and children?
A: Most recipes use non-toxic ingredients like water, vinegar, and dish soap, making them safe for routine home use. Avoid adding harsh chemicals, and always store bottles out of reach of small children.
Q: Can I add fragrance or color to homemade window cleaner?
A: Yes. Add a few drops of essential oil for fragrance, but keep it under 5 drops to avoid streaks. If using food coloring for safety, be careful not to spill or spray it onto clothing or porous materials as it may stain.
Q: Does temperature matter when cleaning windows?
A: Clean windows during cooler parts of the day to avoid rapid evaporation, which can cause streaking. Avoid cleaning in direct sunlight.
Q: What is the best cloth to use with homemade window cleaner?
A: Microfiber cloths, lint-free towels, or even newspaper work best for a streak-free finish. Simply compost newspaper after use to reduce waste.
