How Many Days After Window Tinting Can You Roll Down the Windows?

You can roll down the windows 3 to 5 days after window tinting. Rolling them down earlier may cause the film to wrinkle, reducing its maintenance effectiveness. If you're not in a hurry, waiting until the seventh day to open the windows will make the film adhere more securely. After tinting, proper care is essential. Avoid using nails or sharp objects to peel the edges of the film to prevent dirt from getting underneath. If bubbles appear in the film, have them addressed at the tinting location within 24 hours to avoid wrinkling. Keep a high-absorbency microfiber cloth in the car for cleaning. Avoid hanging suction cup accessories on the windows for the first month, and wait 2 to 3 weeks before washing the windows.
