The inventor has found that heating of the piece of chewing gum to be removed, followed by a mechanical action thereon, whereby the surface area of the piece of chewing gum is enlarged, and subsequently feeding an agent removing the adhesive property of the chewing gum brings about good results. The piece of chewing gum to be removed is here initially heated, whereby it becomes soft, so that the mechanical action can take place more easily.
