How to Clean Car Glass Without Streaks — Pro Tips for Crystal Clear Windows
Nothing ruins a clean detail like streaky glass. Here’s how to get crystal-clear, streak-free car windows every time — no fancy tricks, just the right method.
Streaky, hazy windows are one of the most common detailing frustrations — especially on the inside of the windshield. But it doesn’t have to be that way. With the right tools and process, you can clean glass like a pro every time.
Why Glass Gets Streaky
Streaks are usually caused by:
- Using the wrong towels (too fluffy, not lint-free)
- Overapplying glass cleaner
- Dirty towels or cross-contamination from other products
- Cleaning hot glass or in direct sun
Let’s walk through how to fix all that and get perfect results every time.
What You’ll Need
- High-quality glass cleaner (avoid household cleaners with ammonia)
- Softer Than Soft Microfiber Towel (for final wipes) — shop here
- Secondary clean microfiber (can be an Everyday Microfiber Towel)
Step-by-Step: How to Clean Car Glass Without Streaks
Step 1: Work in the Shade or on Cool Glass
Never clean glass in direct sunlight or when the glass is hot — this causes streaking almost instantly. Park in the shade or wait for things to cool down.
Step 2: Use Two Towels
Use one towel for applying the cleaner, and a separate clean, dry towel for buffing. This is the biggest secret to streak-free glass.
Step 3: Spray the Towel, Not the Glass (Especially Inside)
On interior glass, always spray the cleaner onto the towel — not directly onto the glass — to avoid overspray on dashboards and trim.
Step 4: Wipe with Straight Passes, Then Buff Dry
Wipe in straight lines — not circles. Then use your dry towel to immediately buff to a clear finish. Flip the towel frequently for best results.
Step 5: Clean from Multiple Angles
After wiping, look at the glass from different angles and from outside the car. If you see streaks, use your buffing towel to go over it again with light pressure.
Pro Tip for Interior Windshields
Try reaching the bottom corners with a towel wrapped around a foam sponge or interior glass tool. Those areas are often missed and attract haze quickly.
