Window Clean for Car: How to Get Streak-Free, Crystal-Clear Auto Glass

Window Clean for Car: How to Get Streak-Free, Crystal-Clear Auto Glass

Clean windows on your car aren’t just about looks — they’re about safety, too. Glare from a dirty windscreen or smeared side window can seriously mess with your visibility, especially during Perth’s bright sunny days or rainy mornings.

Whether you're prepping for a road trip down south or just want your ride to look sharp, here’s how to properly clean your car windows — inside and out.

Why Car Windows Need a Different Approach

Unlike household windows, car glass has unique coatings and curves, plus it’s exposed to:

  • Road grime

  • Salt (especially near the coast)

  • Tree sap and bird droppings

  • Interior fog and fingerprints

Using the wrong products can leave streaks, damage tint, or create a hazy residue — not what you want when you're navigating the Mitchell Freeway.

What You’ll Need

  • Glass cleaner (ammonia-free if your car windows are tinted)

  • Two microfiber cloths (one for cleaning, one for drying)

  • Optional: Magic eraser for interior gunk, newspaper for final buff

  • Distilled water + vinegar mix for a DIY eco-clean (50/50 blend)

How to Clean Exterior Car Windows

  1. Park in the shade so the cleaner doesn’t dry too fast.

  2. Spray your cleaner directly onto the cloth (not the glass) to avoid overspray on paintwork.

  3. Wipe in a horizontal motion first, then vertical.

  4. Use a second dry microfiber cloth to buff out streaks.

Pro tip: Don’t forget your mirrors and rear window wiper area — they get just as dirty.

Interior Windows? Here’s the Trick

Interior glass collects oils from hands, dash reflections, and even outgassing from plastics (that hazy film). To clean them:

  1. Use a separate cloth just for interiors to avoid rubbing road grime back on the inside.

  2. Spray your cleaner onto the cloth, not directly onto the glass (to avoid drips on your dash or electronics).

  3. Clean in a circular motion, then buff with a dry edge of the cloth.

Magic erasers work wonders on tough haze — just go gentle.

Extra Tips for a Pro Finish

  • Use distilled water in your DIY mix to avoid mineral spots.

  • Avoid ammonia-based products on tinted windows — they can cause fading and peeling.

  • Finish with a piece of crumpled newspaper for a traditional, streak-free polish.

Whether you’re hitting the road or just want that new-car sparkle, taking the time to clean your car windows properly makes a huge difference. And if you’re ever in need of a full property window clean — well, that’s where we shine.
