Is there a big brother? I want to remove this label. It's been stuck for over three years. Changing the curtains now affects the appearance and I want to get rid of it.

1, the glue can be softened by the heat of the hair dryer, then scraped with a hard card while blowing, and finally wiped clean with a cloth.

2. You can also pour the wind oil essence on the sticker, and then wipe it back and forth with a dry cloth after it penetrates into the sticker, and the sticker will be erased.

3. You can also pour one of the washing products such as detergent, meal washing, cleaning agent and soap into warm water, dip the mixed solution with a towel, wet the sticker, rub it, push it with a hard card, and repeat it several times to remove it.
