Methods to remove the Double Happiness sticker from a car windshield include using a cotton cloth soaked with essential balm to scrub, or applying toothpaste with a toothbrush and gently wiping with warm water. Alternatively, you can use a cotton cloth soaked with gasoline for quick cleaning. If the "Double Happiness" sticker has been on the car for too long, causing low-quality color glue to seep into the 3M film, it can only fade slowly with daily exposure to sunlight, or the film may need to be replaced. Precautions for removing stickers: When using gasoline to remove stickers, safety measures must be emphasized. If the color of the "Double Happiness" character has stained and left marks on a white painted door, you can try contacting a shop to have the door repainted. Tips for applying stickers: It is recommended that car owners place the "Double Happiness" character on the outside of the glass. Alternatively, they can use static stickers on the four corners of the 3M film inside the car to attach the "Double Happiness" character to the glass. Another option is to apply a layer of plastic wrap first and then place the "Double Happiness" character on the plastic wrap.

Removing the double happiness sticker from the windshield isn't actually difficult—a hairdryer can do the trick. First, aim the hot air at the sticker to soften the adhesive, making it easier to peel off. For stubborn residue, gently dab some essential balm or rubbing alcohol onto a cotton swab and wipe; these solvents dissolve the glue without damaging the glass film. Never use a blade to scrape, as it may leave scratches on the glass, doing more harm than good. I've personally tried hand cream too—just apply it, wait ten minutes for the oils to penetrate, then wipe clean with a soft cloth. After removal, remember to clean the glass with a glass cleaner to avoid greasy reflections that could impair visibility.

The key to removing stickers from the windshield is choosing the right solvent. For regular stickers, soaking a cloth in warm water with dish soap and applying it for five minutes usually allows the sticker to peel off in one piece. If the adhesive is particularly strong, it's recommended to purchase a professional adhesive remover—spray it on, wait two minutes, then gently scrape with a plastic scraper to avoid damaging the glass. The easiest time to do this is during summer heat, as the sun-warmed adhesive becomes less sticky. After removal, watermarks often remain on the glass; surprisingly, wiping with newspaper dipped in white vinegar works exceptionally well. Remember, don’t rush the process by using a steel wool pad—scratching the glass coating means replacing the entire windshield, which is too costly.

Removing the double happiness stickers left by wedding cars requires patience. Static stickers can be peeled off directly, while adhesive stickers are more troublesome. I usually start by using a fingernail to lift a small corner, then slowly and steadily pull it down. The adhesive residue can be rubbed off with an eraser, and a ballpoint pen eraser works best. Cooking oil can also be used in emergencies—apply it, cover with plastic wrap, and let it sit for half an hour to allow the oil to penetrate the adhesive layer. After removal, the rear window tends to attract dust due to static electricity; spraying some anti-fog spray can keep it clean for a week or two.
