Here are the methods to remove 3M adhesive from a car: If the adhesive is on the car glass, you can first use a hot towel or a hair dryer to heat the adhesive. After a while, when it seems ready, try to peel it off. If it's still difficult to remove, heat it a bit longer. Use a soft cloth dipped in a small amount of gasoline to gently wipe the adhesive area. Since gasoline may have a 'dissolving' effect on certain plastics or paint, be cautious: first test it on an unimportant area to observe the reaction before proceeding. Use a soft cloth dipped in sufficient 95% alcohol and gently wipe the adhesive area. The adhesive will soften and come off easily, and alcohol generally does not damage plastic parts or the car's paint surface. For stains on glass, ceramics, or tiles, a mixture of soap, a little ammonia, and turpentine can be used to easily remove marks, leaving the surface even smoother.
The old decals on my car used 3M adhesive, and I found that heating is the most hassle-free method for removal. Aim a hairdryer at the edge of the adhesive and blow hot air for a few minutes to soften it, then slowly peel it off. For residual adhesive, don’t rush to scrape it off—apply kitchen olive oil or peanut oil, wait about ten minutes, and wipe it away with a cloth. The oil dissolves the adhesive without damaging the car paint. If you don’t have oil, rubbing alcohol works too—just buy the cheap kind from a pharmacy, drip it on a towel, and wipe repeatedly. The key is patience—if it’s too stubborn, reheat it. Avoid using blades or steel wool, as scratches would be a big loss. Finally, rinse the paint with water and apply some car wax for maintenance to prevent aging.
For the first time dealing with adhesive marks on the car, I used a specialized adhesive remover bought online, costing about ten yuan per bottle. First, test spray a small amount in an inconspicuous area to ensure it doesn't damage the paint. For thick adhesive, use a hairdryer to soften it and peel off the base layer, then cover the remaining adhesive with the spray for ten minutes and wipe it clean with a cloth. Wear gloves and ensure good ventilation during cleaning, as the smell can be quite strong. After spraying, rinse with soapy water to prevent the paint from becoming sticky. For small adhesive spots, an eraser can also do the trick—rub back and forth a few times and it will slowly come off. It's advisable to carefully consider the placement before applying new car decals to avoid hassle when removing them later. Regularly check the adhesive's stickiness to minimize residue issues.
