I’ve been using this DIY fingerprint-free glass cleaner for months, and it truly makes a difference in maintaining spotless, gleaming surfaces around my home. The combination of water, vinegar, isopropyl alcohol, and cornstarch creates a powerful yet gentle cleaner that removes fingerprints, smudges, and streaks effectively. What I love most is how versatile it is—I’ve used it on everything from mirrors and glass doors to stainless steel appliances, and it always delivers a streak-free shine. Just remember to shake the bottle well before each use since the cornstarch can settle at the bottom, which helps thicken the solution to cling better to vertical surfaces. This cleaner also benefits from the antiseptic property of isopropyl alcohol, which helps in killing germs while cleaning. Plus, it’s budget-friendly and free from harsh chemicals often found in commercial cleaners. For best results, I spray it lightly on the surface and wipe with a microfiber cloth, which minimizes lint and polishing marks. If you’re concerned about residue, the cornstarch acts as a natural thickener, preventing drips and allowing the cleaner to leave a fine polish without cloudiness. It’s a little trick I learned that really improves the cleaning experience. Overall, this DIY fingerprint-free cleaner is a fantastic eco-friendly alternative that combines common household ingredients into a multi-purpose cleaner. It’s a must-try for anyone looking to reduce their exposure to chemicals and save money while keeping their home shining beautifully.
