Freeze Chewing Gum

This has worked for me. If small item of clothing, put into a zipper freezer bag and pop into freezer to harden up. Pull off gum. If there is a stain residue, and the garment is washable, rub dish liquid into the stain to pre-treat it before laundering. If this is leather, suede or silk, better to take it to a dry cleaner and point out the problem to them.
