How to Clean Windows Without Windex

You don't need Windex or any commercial glass cleaner to get perfectly clean windows. In fact, many professional window cleaners never use it. Here are the best alternatives — most of which you already have at home.

Why Skip Windex?

• Ammonia in Windex can damage low-E coatings on energy-efficient windows
• It's more expensive than homemade alternatives
• The blue dye can leave a tint on some surfaces
• Homemade solutions work just as well or better

Alternative 1: White Vinegar and Water (Best Overall)

Mix equal parts white vinegar and water in a spray bottle. This is the most popular Windex alternative and works excellently on glass. Vinegar cuts through grease and grime, evaporates cleanly with no residue, and leaves no streaks.

Recipe: 1 cup white vinegar + 1 cup water. Optional: add 1 tablespoon cornstarch for extra cleaning power on very dirty glass.

Alternative 2: Dish Soap and Water (Most Accessible)

Add just 2 to 3 drops of dish soap to a bucket of warm water. This is what professional window cleaners use. The key is using very little soap — too much leaves residue and streaks.

Alternative 3: Rubbing Alcohol and Water

Mix 1 cup rubbing alcohol (70% isopropyl) with 1 cup water and 1 tablespoon white vinegar. This solution evaporates quickly, leaves no residue, and is excellent for removing fingerprints and oily smudges.

Alternative 4: Club Soda

Plain club soda works surprisingly well on glass. The carbonation helps lift grime. Apply with a microfiber cloth and wipe clean. Best for light cleaning and touch-ups.

The Right Tools Matter More Than the Cleaner

The cleaning solution is less important than the tools and technique. A squeegee and microfiber cloth with plain water will outperform Windex applied with a paper towel every time.

• Window Squeegee Cleaner with Extension Pole and Microfiber Scrubber — the right tools for streak-free results with any cleaning solution; 12" squeegee, 11" microfiber scrubber, extension pole

Step-by-Step: Cleaning with Vinegar Solution

1. Mix equal parts white vinegar and water in a spray bottle
2. Clean on a cloudy day or in the shade
3. Spray the glass generously
4. Scrub with a microfiber cloth or scrubber
5. Squeegee from top to bottom, wiping the blade after each stroke
6. Wipe edges with a dry microfiber cloth

What to Avoid

• Paper towels — leave lint and fibers
• Newspaper — the ink can transfer to frames (see our guide on cleaning with newspaper)
• Too much soap — leaves residue and streaks
• Ammonia on low-E glass — damages the coating
• Cleaning in direct sunlight — solution dries too fast and streaks

Cost Comparison

• Windex 32oz: approximately $4–5
• White vinegar 32oz: approximately $1–2
• Dish soap solution (per use): pennies

Homemade solutions cost 50–80% less than commercial cleaners and work just as well.
