No matter how careful you are, it's inevitable that you will eventually come in contact with used chewing gum, and have to remove it. Used chewing gum is sticky and if you just begin pulling it off, it will pull and get stringy, only pulling pieces off, while leaving some of the gum and residue behind. Fortunately, it's possible to remove gum from rubber, using materials and substances from your home.
Place smaller rubber items in the freezer for about an hour, or until the gum is hard. Put dirty items, such as sneakers with rubber soles, in a plastic bag before placing in the freezer so your food does not come in contact with the dirty item. For larger items, rub ice cubes over the gum, until the gum is hard and frozen.
Lift and remove the frozen gum, using a spatula or the side of a fork. Do not use a sharp item, such as a knife, or you risk damaging the rubber. Since the gum is frozen, it should come off in one chunk, and should no longer be sticky or stringy when pulled.
Wipe away any remaining gum residue, using a cloth or rag and warm, soapy dish water. If the residue still will not wipe off, apply a spray lubricant, wait a few minutes and wipe off.
If you are unsure where the gum came from, wear rubber gloves to avoid touching someone else's chewed gum.
