Your new windshield is in. For the next day or two, the urethane holding it is still curing. A few simple habits make sure it bonds properly, stays sealed and doesn’t develop a leak or wind noise.
What not to do after windshield replacement
- Don’t drive before the safe drive-away time your technician gives you, usually about an hour.
- Skip the car wash for 48 hours. High-pressure water and brushes can disturb the fresh seal. A gentle hand rinse is fine after a day.
- Don’t slam the doors. Closing doors pushes air pressure against the new glass. Crack a window slightly for the first day.
- Leave the retention tape on for 24 to 48 hours. It holds moldings in place while the urethane sets.
- Avoid rough roads and potholes when you can for the first day.
- Don’t blast the defroster or A/C straight at the glass on extreme hot or cold days.
- Hold off on stickers, toll tags and dash cams stuck to the glass for a day.
Windshield replacement aftercare checklist
- Confirm your safe drive-away time before leaving.
- Leave a window cracked about an inch for the first day.
- Remove the tape after 24 to 48 hours. Peel it slowly, parallel to the glass.
- Check that wipers, rain sensor, defrost and mirror work.
- If your car has driver-assist features, confirm calibration was done and no warning lights are on. See ADAS recalibration.
- Wait 48 hours before an automatic car wash.
Windshield replacement drying time
Urethane cures with moisture in the air. It’s strong enough to drive in about an hour, and it reaches full strength over 24 to 48 hours. Cold, dry weather slows it down. See how long windshield replacement takes.
