Decals can often be difficult to remove. When it comes to removing decals, there are a number of factors to consider. The three most important are the type of decal, the surface to which the decal is applied, and how long the decal has been applied to that surface. Each one of these factors will affect how you go about removing your decal. Some decals require extensive work to be removed, while others can be removed by simply peeling them off of the surface with your fingers. It is important to note that some decals cannot be removed without leaving permanent damage.
