How to Clean the Inside of Your Car Windshield: A Step-by-Step Guide
Cleaning the inside of your car windshield may seem like a simple task, but doing it properly requires the right tools, techniques, and products. Unlike the exterior, the interior glass is prone to accumulating oils from hands, dust from the cabin, and residue from cleaning products. These factors can lead to streaks and reduced visibility if not addressed correctly. Below, we break down the process into easy-to-follow steps, recommend the best products, and provide a comparison table to help you make an informed decision.

Why Cleaning the Inside of Your Windshield Matters
A dirty windshield can significantly impair your vision, especially when driving against the sun or in low-light conditions. Smudges and streaks can cause glare, making it harder to see the road clearly. Regular cleaning not only improves visibility but also enhances the overall appearance of your car’s interior.
Materials You’ll Need
- Microfiber cloths
- Glass cleaner (ammonia-free recommended)
- Isopropyl alcohol (for tough stains)
- Distilled water
- Rubber gloves (optional)
Step-by-Step Cleaning Process
Step 1: Remove Loose Dust and Debris
Use a microfiber cloth or a soft brush to gently wipe away any loose dust or dirt from the windshield. This prevents scratching the glass during the cleaning process.
Step 2: Apply Glass Cleaner
Spray an ammonia-free glass cleaner onto the windshield. Avoid using household cleaners with ammonia, as they can damage tinted windows or leave streaks.
Step 3: Wipe in a Circular Motion
Using a clean microfiber cloth, wipe the glass in small circular motions to lift dirt and grime. For stubborn stains, apply isopropyl alcohol diluted with distilled water.
Step 4: Dry with a Second Cloth
Use a dry microfiber cloth to buff the glass and remove any remaining streaks. This ensures a crystal-clear finish.
