Methods to remove an ETC stuck on the car windshield: 1. Use a hairdryer to heat the contact surface between the OBU device and the glass until it softens, then gently remove it; 2. Soak a towel in hot water and apply it to heat the adhesive tape behind the device; 3. Use a scraper to remove the silicone adhesive. ETC refers to the Electronic Toll Collection system, which is currently the world's advanced toll collection method for roads and bridges. It uses a dedicated short-range microwave communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station. This system processes toll payments through computer network technology and bank backend settlement, allowing vehicles to pass through toll stations without stopping to pay tolls.

Last time I wanted to reposition my ETC device, I tried pulling it off by force and almost cracked the windshield. Later, I learned a good method online: first, use a hairdryer to heat the adhesive area for about 30-40 seconds until the glue softens. Then, gently pry the device off with a plastic card or a dedicated windshield pry tool. Avoid using metal tools to prevent scratching the glass. Any residual adhesive on the windshield can be cleaned with alcohol or adhesive remover—use a tissue to rub it off slowly, don’t rush. Don’t throw away the ETC device immediately; some can still be recycled or reused. You can also contact a service point to check if it’s still functional, since installing it again is quite a hassle. Be careful throughout the process to avoid damaging the device or hurting yourself. I remember this method saved me a lot on repair costs, especially during long drives—paying attention to these small details really matters.

Having driven for many years and replaced my ETC several times, I've found that patience and the right tools are key when removing it. First, use a hairdryer or heat gun to warm the adhesive for a few minutes to soften it. Then, gently pry the ETC device from the edge using a hard plastic card or an old credit card. Be careful not to pull too hard to avoid cracking the glass or damaging the internal circuitry. If adhesive residue remains stubborn, spraying a bit of medical alcohol or vinegar can help wipe it off. The entire process takes about five minutes, but remember to disconnect the vehicle's power in advance to prevent accidental activation. After removal, ensure the glass stays clean to maintain driving visibility, and store the ETC device properly—it may need reactivation before the next installation. Regular window maintenance can extend its lifespan, but never compromise safety for speed.

I'm not very technical, so when removing the ETC device, I asked my car-savvy neighbor for advice. He taught me to first turn off the car's power, then use a hairdryer to gently warm the adhesive part on the back of the ETC for a short while—just to about 30-40 degrees Celsius. Next, carefully pry the edges with a plastic spoon and slowly push the device upward without using too much force. Any leftover adhesive marks can be treated by applying a bit of olive oil with a cotton pad, waiting a few minutes, and then wiping it off to leave no traces. The whole process should be done patiently with safety first to avoid cracking the glass or injuring yourself. Don't throw away the removed ETC device; contact a service center to check if it's still functional. If it's broken, recycle it properly—eco-friendly and hassle-free. This method is perfect for beginners, making it simple and quick to get the job done.
