Windex vs Vinegar (Diluted): Which Should You Use?

Windex vs vinegar for glass cleaning: which gives a streak-free shine? Compare cost, effectiveness, and the best method for sparkling windows.

Quick Verdict

For occasional quick glass touch-ups, Windex is more convenient and slightly better at cutting through greasy fingerprints. For large-scale window cleaning and hard water spots, a vinegar solution (1:1 with water) is dramatically cheaper and nearly as effective. For commercial window cleaning, professional glass cleaner concentrate diluted in bulk is the most cost-effective option by far.
