What You'll Learn

Clean with Baking Soda Paste
Baking soda is a versatile and effective natural cleaner that can help eliminate stubborn odors from your sink sneakers. To start the cleaning process, you’ll need to create a baking soda paste. Mix equal parts baking soda and water in a small bowl until a thick, spreadable consistency is achieved. For example, combine 3 tablespoons of baking soda with 3 tablespoons of water. This paste will act as a gentle abrasive and deodorizer, targeting the odor-causing bacteria and residue trapped in the sneaker material.
Once the paste is ready, focus on the areas of the sneakers that are most affected by the sink odor, typically the insoles, inner lining, and any fabric or mesh sections. Use an old toothbrush or a soft-bristled brush to apply the baking soda paste thoroughly. Ensure the paste penetrates deep into the fabric or material, as this will help neutralize odors at their source. Pay extra attention to the crevices and seams where bacteria and mildew tend to accumulate.
After applying the paste, let the sneakers sit for at least 30 minutes to an hour. This allows the baking soda to absorb the odors and break down any lingering grime. For particularly strong odors, consider leaving the paste on overnight. During this time, the baking soda will work its magic, neutralizing the smell and leaving your sneakers fresher. Avoid letting the paste dry completely, as it may become difficult to remove.
Once the waiting period is over, use a damp cloth or sponge to gently wipe away the baking soda paste. Rinse the cloth frequently to ensure you’re not just spreading the residue around. For stubborn areas, use the toothbrush again to scrub away any remaining paste. After removing the paste, rinse the sneakers thoroughly with clean water to ensure no baking soda is left behind, as it can cause discomfort when worn.
Finally, allow the sneakers to air dry completely in a well-ventilated area, away from direct sunlight or heat sources, as these can damage the materials. Once dry, inspect the sneakers to ensure the odor has been eliminated. If any smell persists, repeat the baking soda paste treatment. Regularly using this method can help maintain freshness and prevent sink odors from returning, keeping your sneakers clean and odor-free.

Use White Vinegar Soak Overnight
White vinegar is a highly effective and natural solution for eliminating stubborn sink sneaker odors. Its acidic properties help neutralize unpleasant smells and break down the bacteria causing them. To use this method, start by preparing a vinegar soak that will work overnight to refresh your sneakers. Fill a basin or your sink with enough warm water to fully submerge the smelly areas of the shoes. Add one cup of white vinegar for every gallon of water used, ensuring a strong enough solution to combat the odor.
Once the vinegar and water mixture is ready, carefully place the sneakers into the basin, pressing them down to ensure all odor-prone areas, like the insoles and fabric, are fully submerged. Let the shoes soak overnight, allowing the vinegar ample time to penetrate the materials and neutralize the odors. The longer the soak, the more effective it will be, so avoid rushing this step. If possible, leave the sneakers to soak for at least 8 to 12 hours for maximum results.
After the overnight soak, remove the sneakers from the basin and discard the vinegar solution. It’s important to rinse the shoes thoroughly with clean water to remove any residual vinegar, as leaving it behind can cause a lingering vinegar smell. Gently squeeze out excess water from the shoes, being careful not to damage their structure. Avoid wringing or twisting, especially if the sneakers have delicate materials or glue bindings.
Finally, allow the sneakers to air dry completely in a well-ventilated area, away from direct sunlight or heat sources, as these can warp or damage the materials. Placing crumpled newspaper inside the shoes can help absorb moisture and maintain their shape while drying. Once fully dry, your sneakers should be free from sink odor, leaving them fresh and ready to wear. This method is not only effective but also budget-friendly and eco-conscious, making it a great choice for tackling sneaker odors.

Wash with Laundry Detergent
Washing your sneakers with laundry detergent is an effective way to eliminate stubborn sink sneaker odor. Start by removing the laces and insoles from the shoes, as these areas often trap moisture and bacteria that contribute to the smell. Fill a sink or basin with warm water and add a small amount of mild laundry detergent—opt for a gentle, fragrance-free option to avoid irritating materials or leaving residue. Mix the water and detergent until it forms a soapy solution.
Next, submerge the sneakers in the soapy water, ensuring they are fully immersed. Use a soft brush or cloth to gently scrub the exterior of the shoes, paying extra attention to areas with visible dirt or stains. For the insoles, if they are removable and washable, clean them separately by lightly scrubbing with the soapy solution. Avoid aggressive scrubbing, as it may damage the material of the sneakers. Let the shoes soak in the solution for about 15–20 minutes to allow the detergent to penetrate and break down odor-causing bacteria.
After soaking, drain the soapy water and rinse the sneakers thoroughly with clean, warm water to remove any detergent residue. It’s crucial to rinse well, as leftover detergent can cause discoloration or attract more dirt. Once rinsed, gently squeeze out excess water from the shoes, being careful not to twist or wring them, as this can distort their shape. For the insoles and laces, rinse them separately and squeeze out the water as well.
To dry the sneakers, stuff them with crumpled paper towels or newspaper to help maintain their shape and absorb moisture from the inside. Avoid direct heat sources like radiators or hairdryers, as they can warp or shrink the materials. Instead, let the shoes air dry in a well-ventilated area, away from direct sunlight. Once completely dry, reinsert the insoles and laces, and your sneakers should be odor-free and refreshed.
For added freshness, consider sprinkling a small amount of baking soda inside the shoes before wearing them. This method not only removes sink sneaker odor but also leaves your shoes clean and ready for use. Regularly washing your sneakers with laundry detergent can prevent odors from building up, ensuring they stay in good condition for longer.

Air Dry in Sunlight
One of the most effective and natural ways to eliminate sink sneaker odor is to air dry your sneakers in sunlight. Sunlight not only helps to dry the shoes thoroughly but also acts as a natural disinfectant, killing bacteria and fungi that cause unpleasant smells. Start by removing the insoles and laces from your sneakers, as these areas often trap moisture and odors. Place all parts of the shoe in a well-ventilated area where they can receive direct sunlight. Ensure the sneakers are completely dry before reassembling them, as residual moisture can lead to recurring odors.
When air drying in sunlight, choose a spot that receives ample sunshine for several hours, preferably during the hottest part of the day. Lay the sneakers flat or use a shoe tree to maintain their shape while drying. The ultraviolet (UV) rays in sunlight penetrate the fabric and rubber, breaking down odor-causing microorganisms. This method is particularly useful for sneakers that have been soaked or exposed to damp environments, such as sinks, where mold and mildew can thrive. Be patient, as thorough drying may take a few hours or even a full day, depending on the weather and humidity levels.
If your sneakers are heavily soiled or have stubborn odors, consider cleaning them before air drying. Use a mild detergent and water to scrub away dirt and grime, then rinse thoroughly. Once cleaned, pat the sneakers dry with a towel to remove excess water before placing them in the sun. Avoid machine drying, as high heat can warp the shoe’s structure. Instead, let the sunlight and fresh air work their magic, naturally deodorizing and refreshing your sneakers.
For best results, pair air drying in sunlight with other odor-fighting techniques. Sprinkle baking soda inside the sneakers before drying to absorb lingering odors, or stuff them with newspaper to help wick away moisture. After drying, inspect the shoes for any remaining damp spots, especially in crevices or seams. If needed, give them additional time in the sun until completely dry. This method is not only eco-friendly but also cost-effective, making it an excellent choice for maintaining fresh-smelling sneakers.
Lastly, make air drying in sunlight a regular part of your sneaker care routine, especially if they frequently come into contact with water or damp areas like sinks. Preventive measures, such as allowing shoes to dry completely after use, can significantly reduce the buildup of odors. By harnessing the power of sunlight, you can keep your sneakers smelling clean and extend their lifespan, ensuring they remain comfortable and odor-free for longer periods.

Sprinkle Odor-Absorbing Cat Litter Inside
One effective and natural way to combat sink sneaker odor is to sprinkle odor-absorbing cat litter inside the sneakers. Cat litter is specifically designed to neutralize odors, making it a practical solution for smelly shoes. Start by selecting a high-quality, unscented cat litter that is known for its odor-absorbing properties. Avoid scented varieties, as they may leave an unwanted fragrance in your sneakers. Once you’ve chosen the right litter, ensure your sneakers are clean and dry before proceeding. Moisture can exacerbate odors, so it’s crucial to let them air dry completely if they’re damp.
To apply the cat litter, begin by loosening the laces and opening the sneakers as wide as possible to allow easy access to the interior. Next, sprinkle a generous amount of the odor-absorbing cat litter directly inside each shoe, focusing on the areas where sweat and bacteria accumulate, such as the toe box and insole. The litter works by absorbing moisture and trapping odor-causing particles, effectively neutralizing the smell. For best results, leave the litter in the sneakers overnight or for at least 8–12 hours to give it ample time to work.
After the waiting period, remove the cat litter by gently shaking the sneakers over a trash can or outdoors. Be thorough to ensure no particles are left behind, as they can become uncomfortable during wear. If there’s any residual dust, use a soft brush or cloth to wipe the interior clean. You’ll notice a significant reduction in odor, as the cat litter has absorbed the unpleasant smells. This method is not only cost-effective but also eco-friendly, as cat litter is a reusable and biodegradable material.
For stubborn odors, consider repeating the process a second time or combining it with other odor-fighting techniques, such as airing out the sneakers in sunlight or using baking soda. However, sprinkling odor-absorbing cat litter inside remains a standout solution due to its simplicity and effectiveness. It’s a handy trick to keep in your arsenal, especially if you’re dealing with sneakers that are frequently exposed to moisture or sweat.
Lastly, remember to store your sneakers in a well-ventilated area after treatment to prevent future odors. Regularly using odor-absorbing cat litter as a maintenance step can also help keep your shoes fresh. This method is particularly useful for sink sneakers, as they often trap moisture and odors due to their design. By incorporating this technique into your shoe care routine, you’ll ensure your sneakers remain odor-free and comfortable to wear.
