How to Get a Streak-Free Finish on Your Car Windows

🚗 Pro Tip: How to Get a Streak-Free Finish on Your Car Windows

There's nothing more frustrating than thoroughly cleaning your car windows... only to find streaks appearing in the sun. For a flawless finish, without residue or streaks, here's the ProShineAuto method for clean, sparkling, streak-free windows.

Why do traces appear?

Before talking about solutions, let's understand the problem:

❌ Using an unsuitable cloth (too rough or fluffy)
❌ Products incorrectly dosed or poorly rinsed
❌ Washing in direct sunlight
❌ Poor drying technique

Even a good window cleaner can leave streaks if applied incorrectly. That's why it's important to follow certain rules.

✅ Recommended Material

For a streak-free finish, equip yourself like a pro:

A good ammonia-free window cleaner (ideally our Crystal View window cleaner )
Two specific microfibers for windows : one for cleaning, one for wiping
Optional: a soft finishing squeegee

*ProShineAuto Tip: Use 300-400 GSM, tightly woven microfibers specifically designed for glass surfaces.

Steps to streak-free windows

1. Work in the shade and on a cool surface

The sun or a hot window accelerates the evaporation of the product, which encourages the appearance of traces.

2. Start with the least dirty sides: the inside

Always clean the inside first: it is generally less dirty than the outside. This prevents the microfibers from getting dirty too early.

3. Spray a little product

A light veil is enough. Excess product is the number one enemy of perfect transparency.

4. First pass with damp microfiber

Wipe with a clean, slightly damp microfiber cloth. This helps loosen dirt.

5. Second pass with dry microfiber

Use a second clean, dry microfiber cloth to wipe in straight motions:

Inside: Wipe in vertical motions
Outside: Wipe in horizontal motions

✅ This makes it easier to spot the origin of any remaining traces. If they are vertical, they come from the inside. If they are horizontal, they come from the outside.

6. Check in raking light

This is the best way to spot any residual traces.

💡 Bonus: The interior counts too

Streaks on the inside of windows are often caused by oil vapor, air conditioning, or tobacco . The method is the same, but change the microfibers to avoid bringing dirt from the outside back into the passenger compartment.
