How to Remove the ETC from the Car Windshield?
2 Answers
The methods to remove the ETC from the car windshield are: 1. Use a hairdryer to blow hot air at the joint between the OBU device and the windshield. The adhesive tape behind the device will soften when heated, reducing its stickiness. The owner can then slowly twist and remove the OBU device by hand or use a plastic scraper to gently pry it off; 2. Soak a towel in hot water and place it on the outside of the windshield. This will also heat the adhesive tape behind the OBU device. Once the tape softens, the device can be removed; 3. Use sunlight to heat the adhesive tape behind the OBU device. The owner can park the car in an open area on a hot, sunny day, allowing the device to be exposed to intense sunlight and soften, after which it can be removed.
Last time I helped a friend remove an ETC device, I first used a heat gun to blow at the edges of the device for a few minutes to soften the adhesive. Keep the heat gun at a safe distance to avoid overheating the glass. Then, I slowly pried up a corner with a plastic card and gently pulled until the entire device separated. Never force it off, as this could damage the device or leave scratches on the glass. After removal, there’s often adhesive residue left on the glass, which can be cleaned with alcohol or a dedicated adhesive remover. Actually, removing an ETC device is quite common—for example, when selling an old car and keeping the device, or replacing a faulty unit. I recommend doing this in a shady spot to minimize heat damage, and afterward, check if the device is still functional for reuse. In short, take your time for a clean job—safety first. It only takes a few minutes and is much easier and cheaper than visiting a repair shop.
