If you find gum stuck to the fabric of your child's backpack, throwing it in the washing machine is unlikely to remove it. By following a few easy steps, you can remove the gum first and then tackle any remaining residue or stain left behind.
Put on rubber gloves.
Rub the gum on the backpack with your gloved finger. Roll the gum into little bits and pull them off.
Put the backpack in the freezer. Keep it there for about an hour so the gum freezes.
Scrape against the fabric of the backpack with a plastic knife to remove the frozen gum.
Scrub the fabric gently with a soft toothbrush to remove any stubborn remnants.
Treat any remaining stain or greasy residue by sponging on dry cleaning solvent, rubbing in liquid dish soap or apply a prewash spray.
