No. Think about it this way. A story on a social media platform is like someone's personal statement or piece of art for a short period of time. They get to decide how it looks. Stickers are part of their creative choice. Only the person who posted the story has access to the tools to modify it. You as an outside viewer don't have the option to remove something like a sticker from their story. It's all about respecting the privacy and creative control of the story creator.
Sure. Most social media platforms that support stories have an edit function. After you post a story, you can access the edit mode within a certain time limit. In this mode, you can simply tap on the sticker you want to remove and there should be an option to delete it. It's quite straightforward once you know where to look for the edit option.
Another option is to use a piece of duct tape. Press it firmly onto the sticker and then quickly pull it off. This might take a few tries but can sometimes do the trick without harming the comic.
One way to do it is to apply a little rubbing alcohol to the sticker. Let it soak in for a bit, and then carefully peel it off. But be careful not to get the alcohol on the comic itself too much.
I'd suggest using some cooking oil. Put a tiny amount on a tissue and rub it over the residue. Let it sit for a bit, then wipe it clean. Another option is to use white vinegar. Soak a cloth in it and dab at the residue. But always test these methods on a small, inconspicuous area first to make sure they don't harm the manga.
One way to get rid of sticker residue from comic books is to use some warm soapy water. Soak a soft cloth in it and gently wipe the area. Just be careful not to be too rough and damage the pages.
