For stickers on the glass, a professional adhesive remover can be used. For large-area stickers, a hairdryer can be used to remove them. The purpose of the hairdryer is to soften the adhesive backing, allowing the sticker to be peeled off in one piece.

With over a decade of driving experience and applying numerous car decals, I've gained expertise in removing old stickers. First, use a hairdryer to heat the sticker for a few minutes to soften the adhesive—avoid excessive heat to prevent damaging the paint. Then, gently scrape it off with a plastic scraper or an old credit card; never use metal tools as they can leave scratches. For any adhesive residue, spray some adhesive remover or rubbing alcohol and wipe it clean with a soft cloth. Finally, wash the area with soapy water and apply wax for protection. The process requires patience, especially for long-standing stickers with stubborn adhesive, which may need multiple attempts. Remember to work in the shade to avoid direct sunlight hardening the glue. This cost-effective and safe method has worked well for me multiple times, keeping the paint looking glossy and new.

As someone who frequently deals with car detailing, I recommend starting with heating when removing old decals. Use a heat gun or a household hairdryer set to medium heat to warm the edges of the decal, softening the adhesive. Then, carefully lift a corner using a plastic scraper. Peel it off slowly to avoid damaging the paint by pulling. For any leftover adhesive, apply a professional adhesive remover, wait a few minutes for it to dissolve, and then wipe it clean with a soft cloth. If the adhesive is particularly stubborn, try using WD-40 or alcohol as an alternative. After cleaning, rinse with water and apply car wax for protection. Ensure proper ventilation throughout the process and avoid skin burns from the heating tools. This method works for most decals, but for large stickers or adhesive that has penetrated the paint layer, it's best to seek professional help as they have more efficient tools and techniques.

I think the key to removing long-stuck car decals is using the right tools and methods. First, heat and soften the glue, such as with a hair dryer for a few minutes, then slowly peel it off. Use alcohol to remove any residual adhesive, and finally, wash and wax the car. The whole process is simple and eco-friendly—avoid using harsh chemical agents.
