Use of ice, scouring powder and power washer machines are some effective chewing gum removal methods. Chemicals like paint stripper and orange peel oil also remove chewing gum effectively.
Ice helps in removal of fresh chewing gum. It forces the gum to freeze for easy removal. Combine scouring powder and water to dislodge hardened gums, and then scrub the spot. A power washer machine is ideal for removal of multiple chewing gum deposits on surfaces such as concrete. Try paint stripper or orange peel oil for removal of gum on upholstery. Do not mix the two chemicals, since they function differently.
