Method 2: chemical agent division
First of all, we can manually tear off the large stickers that can be torn off first. Then apply banana water or some gasoline to the remaining stickers (be sure to protect your hands when handling them as they are corrosive) and leave them for a few days before rubbing them to clean. Acetone solution can also be used for cleaning. But keep in mind that if it is a plastic steel window, do not get to the plastic steel, when using the amount is not too large, because acetone can dissolve plastic, so the plastic steel window can also dissolve. Don't worry too much. Acetone doesn't dissolve very fast, but it evaporates fast.
