Gum is a sticky substance that is meant to be chewed for a long period of time without coming apart. If, by accident, you somehow sit on a piece of chewed gum, it can be tricky to remove the gunk from your pants. Gum can also get stuck to a pair of pants if a piece is left in the pocket when the clothes are laundered. But if you are willing to do a little work, you will be able to remove the gum from the pants.
Freeze the Gum Out
Put the pants in a plastic bag and place it in the freezer.
Wait two hours and take the pants out of the freezer. You will notice that the gum is now hard as a rock.
Chisel the gum off the pants with a butter knife. The gum may even come off in one big lump. Just go slowly, so that you don't accidentally rip the pants with the knife.
Iron the Gum Off
Lay a piece of cardboard on an ironing board.
Put the sticky pair of pants on the cardboard, with the gum side facing down. The gum will be between the cardboard and the pants.
Iron the pants over the spot where the gum is stuck. Do this for three to five minutes, or until all of the gum has begun to stick to the cardboard instead of the pants.
