How to Clean Tinted Windows Without Damaging the Film

Wait one week first
New tint needs time to cure. Do not clean the inside of tinted windows for about a week after installation. The outside of the glass is fine to wash anytime — the film is on the inside. More in our guide on how long tint takes to dry.
What to use
- Ammonia-free glass cleaner, or simply water with a few drops of mild soap
- Two clean microfiber cloths — one to clean, one to dry and buff
- A soft rubber squeegee if you like (optional)
Ammonia is the ingredient to avoid — over time it can dry out and discolor window film. Many standard household glass cleaners contain it, so check the label.
How to do it
- Spray the cleaner on the cloth, not directly on the window, so it does not drip into door panels or onto electronics.
- Wipe gently top to bottom. No hard scrubbing.
- Flip to a dry microfiber and buff off streaks.
- For the top edge, roll the window down an inch, clean the edge carefully, then roll it back up.
What NOT to do
- No paper towels — they can leave fine scratches and lint.
- No razor blades, scrapers or rough sponges on the inside of the glass.
- No suction-cup mounts, stickers or tape on the film.
- Careful with seat belts — a buckle snapping back into the side window can nick the film.
Scratched or damaged?
Small scratches in window film cannot be polished out like paint. If a window gets damaged, the fix is to replace the film on that window. If it is still under warranty, contact us first.
