The service experts at Mercedes-Benz of West Covina have created this step-by-step guide on how to clean inside car windows and answered common questions, like “Can you use Windex on car windows?” Read on to keep your vehicle’s glass spotless and your drive safe.
How to Clean Inside Car Windows
Cleaning the inside of your car windows takes just a few simple steps:
- Wipe Away Surface Dust
Use a clean, dry microfiber cloth to remove loose dust, dirt, and debris from the interior glass surfaces. - Apply Glass Cleaner
Spray an automotive-safe glass cleaner onto a microfiber towel (not directly on the window to avoid overspray) and thoroughly wipe down the windshield and windows. - Remove Grease and Oils
Using a second microfiber towel, apply a small amount of rubbing alcohol to break down any oily residues from fingerprints or dashboard off-gassing. - Polish for a Streak-Free Shine
Finish with a final coat of glass cleaner or polish, wiping in a vertical motion to reduce streaks and improve clarity.
Can You Use Windex on Car Windows?
One of the most frequently asked questions we hear from Glendora drivers is: Can you use Windex on car windows?
The short answer is yes—but use with caution:
- Untinted or Factory-Tinted Windows:
Windex is generally safe to use on standard and factory-tinted windows. - Aftermarket Tint:
If your vehicle has aftermarket window tinting, especially non-metallic films, avoid ammonia-based products like original Windex. These may degrade the tint over time. - Interior Surfaces:
Be careful when cleaning interior windows—Windex overspray can discolor or damage leather seats, dashboards, or trim. - When in doubt, opt for an ammonia-free glass cleaner specifically formulated for automotive use.
Additional Tips for Streak-Free Windows
Achieve a professional finish with these expert tips:
- Use Microfiber Towels: Skip the paper towels to avoid lint and streaks.
- Reach Tricky Spots: Invest in a reach-and-clean tool from our parts department for hard-to-access corners of the windshield.
- Wipe Correctly: Start with circular motions for full coverage, then switch to vertical strokes for a streak-free shine.
