How to Properly Clean Your Interior Windshield for a Streak-Free Shine – The Simple, $5 Fix That Transforms Night Driving

✅ How to Clean Your Interior Windshield – The Streak-Free Method

Time: 20 min | Cost: ~$5–$8

🛒 What You’ll Need

Microfiber towel (high-quality, lint-free — this is key!)

🔸 Pro Tip: Use two — one for cleaning, one for buffing.

Isopropyl alcohol (70% or higher) or dedicated interior glass cleaner (like Invisible Glass or Chemical Guys)

🔹 Why alcohol? It cuts through grease without leaving residue.

Plastic razor blade or credit card (for stubborn spots — optional but powerful)

All-purpose cleaner (optional) – For the dash area to prevent future transfer

❌ Avoid: Paper towels, newspaper, ammonia-based cleaners, or dirty rags.

👩‍🔧 Step-by-Step Instructions

1️⃣ Remove Dust & Debris

Wipe the glass lightly with a dry microfiber cloth to remove loose dust.

Open windows slightly to avoid fumes in a closed space.

2️⃣ Spray the Cleaner

Spray isopropyl alcohol or glass cleaner directly onto the microfiber towel — not the windshield (to avoid overspray on dash).

Never spray near vents or electronics!

3️⃣ Wipe in One Direction

Using firm pressure, wipe the glass in straight lines — horizontal or vertical, but stick to one direction.

💡 Why? Circular motions swirl the grease; straight lines make streaks visible so you can fix them.

4️⃣ Flip & Buff

Flip the towel to a clean side and buff lightly in the opposite direction to remove any remaining haze.

5️⃣ Tackle Tough Spots (If Needed)
