To get gum off shoes, make it cold and hard first, then lift it. Hold a bag of ice on the gum until it turns brittle, prise it up with something blunt such as a table knife, and pick the last pieces out of the tread while they are still frozen. Warm gum smears; frozen gum cracks.
Whatever is left after that is usually a thin, greasy film, and that is a second, separate job. Below: the bottom of the shoe, uppers in canvas, mesh, leather and suede, and what to make of the peanut butter and WD-40 tricks.
Why gum fights back, and why cold wins
At room temperature chewing gum is soft and stretchy. Pull it and it strings out; press it and it goes deeper into whatever it is sitting on, whether that is the grooves of an outsole, the weave of canvas or the holes in mesh. Cold changes its behaviour. Texas A&M's extension service says to apply ice "to harden the sticky residue", then crack or scrape off the excess. The University of Georgia's textile advice is the same idea: a plastic bag of ice held against the gum until it sets hard, then a dull tool, like a table knife, to lift it away.
The tool matters as much as the ice. A sharp blade or hard scrubbing can do more harm than the gum did. Texas A&M warns that rubbing "may roughen the fabric, damage the fibers or remove color through abrasion". So: blunt edge, light pressure, and another round of ice whenever a piece goes soft again.
How to get gum off the bottom of your shoe
Most gum ends up on the outsole, which is the easy case: rubber is tough, and the only real difficulty is the tread.
- Ice it. Put ice cubes in a sealed sandwich bag and hold it on the gum until it is hard and no longer tacky. The bag keeps meltwater off the shoe. A common alternative is to seal the whole shoe in a bag and put it in the freezer for a while.
- Lift the bulk. Slide a table knife, a plastic scraper or a lolly stick under the edge of the gum and lever it up. Go slowly at the edges, where it is thinnest.
- Pick out the grooves. Gum pressed into the tread breaks into crumbs. Pick them out with a toothpick or the corner of the scraper. When they start to soften, ice again.
- Scrub what is left. Finish the outsole with a brush and a little mild soap and water, the usual treatment for sneaker soles. Let it dry before you walk on it.
Old gum that has been walked flat and gone black with dirt gets the same treatment. It just takes more rounds, because it is thinner and packed into every groove. If it happens at school or at work, a bag of ice from the canteen or a café is all you need.
Gum on the upper: what changes by material
Gum on the side of the shoe or the toe is less common and more delicate. The cold-and-lift step is the same on every material; what you do about the residue is not.
Canvas
Gum works into the weave, so expect more than one round of ice and lifting. The film that stays behind is what Texas A&M calls a dry-type, greasy stain, and it treats it with a grease solvent; the American Cleaning Institute suggests a prewash stain remover or cleaning fluid. Both are laundry sources written for clothes, so on a shoe dab a small amount on, rather than soaking the panel, test it first on the inside of the tongue, and wipe it off with a damp cloth. Then clean the whole panel so you don't leave one bright patch. Our canvas guide covers that part. Keep the shoe away from the dryer until the mark is gone: heat sets stains.
Mesh and knit
Mesh is an open structure, and gum gets into the holes. Lift across the surface with the blunt edge rather than digging down into it, and work in small pieces. The residue step is the same as canvas, tested on a hidden spot first, and with a lighter hand.
Smooth leather and patent
Freeze it and lift it, working in from the edges. If a film remains and you want to try a solvent, test it on a hidden spot first, such as the inside of the heel. On patent, wipe with a barely damp cloth and keep harsh chemicals off the glossy coating.
Suede and nubuck
Freeze it, then pick it off in small pieces rather than scraping, so you take as little nap with it as you can. Once the shoe is dry and the gum is gone, brush the nap in one direction to lift it back up. Don't wet the area to chase the last bit. The general method is in our suede and nubuck guide.
Slippers, sandals and laces
On fabric slippers and sandal straps the cold-and-lift method is the same. For the residue, follow the label: many slippers use fleece, wool or felt, and those have their own rules. Gum in a lace is easiest to deal with by taking the lace out, freezing it and picking it out; if it won't come clean, laces are cheap to replace. See how to clean shoelaces.
Peanut butter, WD-40 and hair dryers
Search for gum on shoes and you will find all three, usually in a confident Reddit thread. We found no reliable source that backs any of them for shoes, so we don't recommend them. Two points are worth knowing anyway. Peanut butter and WD-40 both leave an oily layer behind, and the film gum leaves is already a greasy stain, so on canvas or suede you would be adding a second mark to clean off. Heat does the opposite of what you want: it makes gum softer and stickier, which is exactly the state ice gets it out of.
Where our foam fits
It doesn't fit the gum itself, and we would rather say so. SneakerSalt Shoe Cleaning Foam is water, a plant-derived surfactant, sodium citrate and glycerin. It has no solvents, so it won't dissolve gum or its greasy film. Where it earns its place is afterwards: once the gum is off, two pumps where it was, on the outsole, midsole or upper, ten seconds, and a dry wipe take up the ordinary surface grime around the spot, so it matches the rest of the shoe. The brush and cloth in the box cover the brushing and wiping in the steps above.
Questions people actually ask
What dissolves chewing gum?
The guides we trust don't try to dissolve it at all. They harden it with ice, lift it off, and only then treat the greasy residue, with a grease solvent or prewash stain remover on fabric, tested on a hidden spot first.
Will vinegar dissolve gum?
We found no reliable source showing that it does, so we wouldn't count on it. Ice and a blunt edge are what the extension services use.
Does rubbing alcohol remove gum from shoes?
We couldn't find a trustworthy test of it on gum. On a rubber sole you don't need it: ice, a blunt edge and a brush with soapy water deal with it. On an upper, anything solvent-like gets a hidden-spot test first.
Once the gum is gone, the rest of the shoe takes a minute: SneakerSalt foam, $24 with free shipping, brush and cloth included, and if it doesn't clean your shoe you keep the bottle and get your money back.
