5 Best Homemade Window Cleaning Solutions You Should Try

TLDR;

The best homemade window cleaning solutions use simple ingredients like vinegar, dish soap, and rubbing alcohol to deliver streak-free results without harsh chemicals. These DIY recipes are budget-friendly, eco-conscious, and highly effective for both residential and commercial windows.

Why Homemade Window Cleaning Is the Way to Go

Homemade window cleaning solutions are not just about saving a few bucks—they're healthier for your home, safer for your family, and better for the planet.

• Eco-friendly: Most store-bought cleaners contain volatile organic compounds (VOCs) that contribute to indoor air pollution. Homemade options eliminate that risk.
  
• Non-toxic: No harsh fumes or skin-irritating agents. Perfect for homes with kids, pets, or allergy-prone individuals.
  
• Cost-effective: Why pay for overpriced brands when you likely already have the ingredients at home?
  
• Customizable: Add essential oils for scent or adjust ingredients based on window type and dirt level.
  
  

Did You Know?


Conventional window cleaners often contain butyl cellosolve—a solvent linked to headaches, dizziness, and even kidney or liver damage with long-term exposure.

Essential Tools & Ingredients You’ll Need

Before diving into the recipes, gather the right tools for a streak-free finish. Here's what you’ll need:

Ingredients:

• White vinegar: Natural disinfectant and grime cutter
  
• Rubbing alcohol (isopropyl): Speeds up drying, prevents streaks
  
• Dish soap: Breaks down greasy buildup
  
• Cornstarch: Adds scrubbing power
  
• Ammonia (optional): Powerful cleaner—use with caution

Tap Water vs. Distilled Water

Tap water can leave mineral deposits on glass, especially in areas with hard water. If you're going for spotless clarity, distilled water is your best bet.
