👩🍳 How to Make It:
- Combine Ingredients
In a clean spray bottle, pour in the water, vinegar, rubbing alcohol, and cornstarch. - Shake Well
Shake vigorously until the cornstarch is fully dissolved. This is key! Cornstarch can settle at the bottom, so always shake before each use. - Spray & Clean
Spray directly onto windows, mirrors, or glass tabletops. - Wipe & Shine
Use a lint-free microfiber cloth or newspaper to wipe clean. Work in circular motions, then finish with vertical swipes for a streak-free glow.

Marion Lancaster says:
“I can only get my windows to look clean if I use a squeegee. I spray, scrub, then squeegee. I’m going to try your formula — love that it uses ingredients I already have!”
Joe Serratore asks:
“Why add cornstarch to homemade glass cleaner?”
Because it acts as a fine polishing agent — that’s the secret to the sparkle.
Mary Hickey Weir suggests:
“I find the cornstarch leaves a residue. I use this recipe but leave the cornstarch out — it works out perfect!”
✅ Tip: You can absolutely leave out the cornstarch if you’re concerned about residue. Just be sure to use a clean, dry cloth and wipe well.
🔄 Variations:
- No Alcohol? Replace with more vinegar, or use vodka as a substitute.
- No Vinegar? Use lemon juice for a more citrusy cleaner.
- Cornstarch-Free Version: Mix just water, alcohol, and vinegar for a simple and effective alternative.
