Yes, most stickers will likely melt or be damaged if you put them on an oven and bake them. Stickers are typically made from materials such as paper, vinyl, or adhesive substances that are not designed to withstand high temperatures. When exposed to the heat inside an oven, these materials can melt, release harmful fumes, or catch fire.
If you accidentally place a sticker on your oven and need to remove it, it's best to do so before turning on the oven or applying heat. To remove a sticker from an oven or any other surface, you can use a heat-resistant scraper or a combination of heat (from a hairdryer) and a gentle solvent like rubbing alcohol or cooking oil to loosen the adhesive. However, always be cautious and avoid using harsh chemicals that could damage the oven's surface or create additional hazards.
