This solution for removing gum from your shoe requires that you either have this product already or that you purchase it. Take a can of WD-40 and spray the area of the shoe with the gum. Allow at least one minute to pass. Use a paper towel or rag to wipe away the gum and the oily spray from the shoe. Use a clean rag or paper towel to wipe the shoe a second time to remove any additional residue.
