How to Remove Smell From Shoes Instantly: 9 Fast Fixes (Plus When to Call a Pro)
Quick answer: The fastest way to remove smell from shoes instantly is to sprinkle baking soda inside them and let it sit overnight, or place them in the freezer in a sealed bag for a few hours — both kill odor-causing bacteria fast. For smells that keep coming back, the bacteria are usually living deep in the foam midsole and insole, which home remedies can’t fully reach — that’s where a professional deodorizing clean makes the difference.
Smelly shoes aren’t really about “smell” at all — they’re about bacteria feeding on sweat trapped inside warm, damp foam. Below are the fastest fixes you can do right now, followed by what actually gets rid of the smell for good.
9 Ways to Remove Shoe Smell Instantly
1. Baking Soda (Best All-Around Fix)
Sprinkle 2–3 tablespoons of baking soda directly into each shoe, or use it inside old socks tied off at the top. Leave overnight, then shake out. Baking soda neutralizes acidic sweat odor on contact.
2. Freezer Method
Place shoes in a sealable plastic bag and leave them in the freezer for 6–8 hours. Cold temperatures kill most of the bacteria responsible for the smell.
3. Direct Sunlight
UV light kills odor-causing bacteria naturally. Leave shoes in direct sun (insoles removed if possible) for a few hours — this also helps dry out any lingering moisture.
4. Tea Bags
Unused, dry tea bags placed inside shoes overnight absorb moisture and odor thanks to natural tannins.
5. Rubbing Alcohol Spray
Lightly mist the inside of the shoe with rubbing alcohol using a spray bottle. It evaporates quickly and kills bacteria on contact — avoid on suede or leather.
6. Activated Charcoal Inserts
Charcoal shoe deodorizers absorb odor and moisture continuously, and can be reused after a few hours in the sun to “recharge” them.
7. Cedar Shoe Inserts
Cedar naturally absorbs moisture and has mild antibacterial properties, making it a good everyday-use option between wears.
8. Dryer Sheets
Tuck a fresh dryer sheet into each shoe overnight for a quick, mild fragrance fix — best combined with baking soda rather than used alone, since it masks rather than removes odor.
9. Wash Removable Insoles Separately
Most odor lives in the insole, not the shoe itself. Pull it out and hand-wash with a bit of detergent and warm water, then air dry fully before replacing.
Why the Smell Keeps Coming Back
Home remedies treat the surface, but odor-causing bacteria burrow into the foam midsole and stitching over time — areas a quick baking soda treatment or spray can’t fully reach. If your shoes smell bad again within a day or two of wearing them, that’s a sign the bacteria live deeper in the shoe’s structure, not just on the surface.
This is exactly what a professional sneaker cleaning and deodorizing service is built to fix — deep-cleaning and treating the insole, foam, and lining rather than just masking the smell on top.

Frequently Asked Questions
How do you get the smell out of shoes fast? Baking soda left in overnight or a few hours in the freezer are the two fastest at-home methods. Both work by neutralizing or killing the bacteria causing the odor.
What is the best home remedy for smelly shoes? Baking soda is generally the most effective and accessible remedy — it neutralizes acidic sweat odor rather than just masking it.
Why do my shoes still smell after I wash them? Most odor lives in the insole and foam midsole, not the outer shoe. Machine washing the exterior often leaves the source of the smell untreated.
Can vinegar remove shoe odor? Yes — a diluted vinegar and water spray can help kill bacteria, but it should be spot-tested first, especially on suede or leather, and shoes must dry fully before wearing.
How often should I deodorize my sneakers? For daily-wear shoes, a quick baking soda treatment every 1–2 weeks helps prevent buildup. For deep-set odor, a professional cleaning every few months keeps shoes fresh long-term.
Is professional shoe cleaning worth it for odor? If home remedies only mask the smell temporarily, professional cleaning is worth it — it treats the insole and foam directly, which is where persistent odor actually comes from.
