Assess Mildew and Gather Supplies
Identify Mildew, Evaluate Fabric Type, and Safety
Mildew on shoes typically appears as powdery or fuzzy patches, often green, black, or white. It thrives in damp, dark environments and leaves a musty odor that lingers even after cleaning. Distinguish mildew from dirt by examining growth patterns: mildew forms discrete, threadlike colonies rather than smeared grime.
Before cleaning, assess the fabric or material to choose a method that won’t harm the shoe. Leather, suede, mesh, canvas, and synthetics each respond differently to moisture and cleaners. A colorfastness test on a hidden area helps prevent discoloration during treatment.
Embedded mildew inside soles or foam can be more difficult to remove than surface growth. Wear a disposable mask and gloves to limit exposure to spores, and work in a well-ventilated area. If the growth is extensive or the odor persists after initial treatment, consider consulting a professional cleaner or replacing the item.
- Protective gear: N95 mask or equivalent, nitrile gloves, and eye protection
- Ventilation: fan or open window to ensure air flow
- Cleaning agents: white vinegar, baking soda, hydrogen peroxide (3%), mild detergent
- Material-specific products: leather cleaner, suede cleaner, fabric cleaner
- Tools: soft brush, old toothbrush, microfiber cloths, spray bottle
- Absorbents: baking soda or silica gel packets, activated charcoal (optional)
Gather Tools, Cleaners, and Protective Gear
Assemble a dedicated cleaning kit to prevent cross-contamination with other items. Include a soft-bristle brush for gentle scrubbing and a microfiber cloth for wiping residue. Have a spray bottle filled with warm water for rinsing and a separate container for cleaning solutions.
Choose cleaners appropriate for each material you’ll treat. For fabrics and canvas, mild detergent or enzyme cleaners work well. For leather, a specialty leather cleaner with conditioning properties is preferable to avoid cracking or drying out the surface.
Plan to use breathable storage during drying, such as a rack or shoe tree, to maintain airflow. If you lack a heat source, a basic household fan can accelerate drying without direct heat. Keep a spare set of insoles and laces handy for after-clean replacement if needed.
- Soft brush and toothbrush for scrubbing
- Microfiber cloths for gentle wiping
- Spray bottle for even application
- Water, white vinegar, baking soda, hydrogen peroxide, mild detergent
- Leather and suede cleaners (if applicable)
- Insoles and laces for replacement after cleaning
Quick Cleaning Steps That Work Across Most Shoes
Initial Cleaning and Surface Mold Removal
Begin by removing loose surface mildew with a dry brush or an old toothbrush. Gently brush in one direction to fling away loose spores without embedding them deeper. If moisture is present, dab—don’t soak—the area to avoid saturating the interior layers.
Prepare a light cleaning solution appropriate for the material: a mild detergent dissolved in warm water works for most fabrics, canvas, and mesh. Apply the solution with a microfiber cloth or brush, focusing on affected areas while avoiding aggressive scrubbing. Rinse with a clean, damp cloth to remove soap residue.

For stubborn patches, allow a brief pre-soak time of 5–10 minutes with a cloth dampened in the cleaning solution. Reassess the stain and mildew footprint after the initial wipe to decide if stronger treatment is necessary. Always work in a ventilated area to minimize inhalation of spores and fumes.
- Dry brush to remove loose spores
- Use warm water with mild detergent for most fabrics
- Avoid soaking footwear to prevent interior moisture buildup
Sanitize with Safe Chemical Alternatives
White vinegar is a go-to mildew sanitizer due to its acidity and odor-reducing properties. Mix equal parts white vinegar and water in a spray bottle and apply to the affected surfaces. Let it sit for 5–10 minutes, then wipe away with a clean cloth.
Baking soda paste can tackle surface staining and deodorize. Mix baking soda with a small amount of water to form a thick paste, apply to mildew spots, and gently scrub with a soft brush. After a short dwell time, wipe clean with a damp cloth and allow to air dry.
Hydrogen peroxide (3%) is effective on white or pale fabrics but can affect some colors. Test on a hidden area first, then apply sparingly with a cloth or spray. After 5–10 minutes, blot and rinse to remove any residue before drying.
- Use vinegar to sanitize and deodorize
- Apply baking soda paste for stains and odor
- Test peroxide on inconspicuous area before broad use
Cleaning by Material Type
Clean Fabric, Mesh, and Canvas Shoes
Fabric, mesh, and canvas respond well to gentle cleaning and thorough rinsing. Start by removing laces and insoles to clean every seam and surface thoroughly. Pre-treat heavy mildew with a diluted detergent solution applied with a soft brush.
Use a 1:1 mixture of water and a mild detergent, then scrub in circular motions to lift grime and mildew colonies. Rinse the surface with clean water using a cloth to avoid soaking the shoe. If odors persist, repeat a vinegar wash and baking soda deodorizer after drying.
After cleaning, stuff the shoes with newspaper or paper towels to help maintain shape and absorb moisture. Allow to air dry in a well-ventilated area away from direct heat or sunlight. Complete drying should be thorough to prevent regrowth of mildew during storage.
- Remove laces and insoles for full access
- Pre-treat visible mildew with detergent solution
- Rinse with clean water and air dry completely
Clean Leather and Faux Leather Shoes
Leather shoes require gentler handling to avoid cracking and color loss. Wipe down with a cloth dampened in a mild soap solution or a dedicated leather cleaner. Avoid saturating leather surfaces; excess moisture can damage the material.
After cleaning, apply a leather conditioner to replenish oils and maintain flexibility. For stubborn mildew on leather, consider a specialized leather cleaner and follow the product’s instructions precisely. Do not use bleach on leather, as it damages the finish and can cause discoloration.
Dry leather slowly in a shaded area with good air circulation. If odor remains, use a light vinegar mist (diluted) or a leather-safe deodorizer following manufacturer directions. Reassemble insoles and laces once completely dry to prevent moisture entrapment inside the footwear. (See Also: What to Wear with Brown Suede Boots: Outfit Ideas)

Suede and Nubuck Care
Suede Cleaning Basics
Suede is delicate and highly susceptible to water damage. For mildew on suede, use a suede brush to lift residues and dirt without saturating the surface. A suede eraser or a light brush can help remove small patches of mildew without introducing moisture.
Avoid traditional soaps and large amounts of water. If you must use moisture, keep it minimal and targeted, applying with a cloth rather than dripping liquid onto the surface. Finish by brushing again to restore nap and texture, then allow to air dry in a ventilated area away from heat.
If the mildew is embedded in nap or fibers, consider a professional suede service for deep cleaning. For light mildew, a commercial suede cleaner following the label’s instructions can be effective. Always test on a concealed area before proceeding widely.
- Use suede brush and eraser for light mildew
- Avoid soaking suede; use minimal moisture
- Test cleaner on hidden area first
Nubuck-Specific Mildew Handling
Nubuck shares similar care with suede but tends to be a bit more durable; treat mildew with care to avoid surface dulling. Use a nubuck-brush or suede brush to lift the nap and dislodge spores. For stubborn patches, a mild cleaner designed for nubuck can be applied sparingly and wiped away promptly.
Do not saturate nubuck; moisture can cause water stains and texture changes. After cleaning, allow thorough air drying and brush the nap again to restore its soft feel. If mildew returns, consider professional cleaning or potential replacement for preserved appearance and function.
Prevention is key with nubuck: store in dry conditions, use protective sprays suitable for nubuck, and avoid humid environments. For ongoing mildew issues, rotate footwear and ensure complete dryness before storage. When in doubt, seek professional advice to preserve the material integrity.
- Brush nubuck with care to lift nap
- Avoid over-wetting nubuck surfaces
- Apply nubuck-safe protective spray after drying
Odor Control and Mildew Neutralization
Absorbing Odors with Baking Soda and Activated Charcoal
Odor is a common companion of mildew; neutralizing it helps prevent regrowth and improves comfort. Fill the inside of each shoe with baking soda to absorb moisture and odors. Leave it in place overnight and shake out before wearing again.
Activated charcoal sachets placed inside shoes can further reduce musty smells, especially in damp environments. Change the sachets periodically to maintain effectiveness. For portable solutions, use breathable cloth bags filled with charcoal that fit snugly inside the toe box.
Additionally, keep the shoes in a dry, ventilated area after treatment to prevent moisture buildup. Repeating this process weekly or after heavy use can maintain a fresher interior. If odors persist, combine with a light cleaning regimen to remove buildup contributing to the smell.
- Baking soda inside shoes overnight
- Activated charcoal sachets for continuous odor control
- Regular replacement of absorbers to maintain effectiveness
Odor Neutralization with Vinegar/alcohol Mist
A mist of white vinegar and water can neutralize odors without leaving residue on many materials. Lightly spritz the interior and surface areas, then allow air drying where ventilation is strong. Avoid over-wetting, especially on leather and suede, to prevent distortion or staining. (See Also: How to Keep Shoe Closet Smelling Fresh: Simple Solutions)
Rubbing alcohol (isopropyl, 70%) can disinfect interior fabrics and cut through mildew odors if used sparingly. Apply to a cloth and wipe interiors, then let dry completely with good airflow. Do not spray directly into the footwear if it could saturate padding or inner seams.
For persistent odors, repeat the vinegar mist and emphasize drying time. If mildew returns, recheck moisture sources in the storage area and consider adding dehumidification. Combine odor treatment with the proper cleaning steps for comprehensive results.
- Vinegar-water spray for odor neutralization
- Rubbing alcohol for interior disinfection (sparingly)
- Avoid saturating materials prone to moisture retention
Drying, Storage, and Prevention
Drying Techniques and Air Circulation
Proper drying is essential to prevent mildew rebound; never dry shoes in direct heat or sunlight, which can warp materials and fade colors. Remove insoles and laces to maximize airflow and speed up drying. Use newspaper or paper towels to wick moisture from the interior and help maintain shape.
Place shoes on a rack, shoe tree, or elevated surface in a well-ventilated area. If humidity is high, use a fan or dehumidifier to remove moisture from the air and inside the footwear. Ensure the interior is completely dry before reassembly to minimize mold recurrence.
For athletic shoes with foam midsoles, consider removing the inner foam components where possible to accelerate drying. In climates with persistent humidity, a dedicated shoe dryer or low-heat setting on a hair dryer (from a distance) can help, but use caution. Inspect after drying to confirm no damp pockets remain.
- Remove insoles and laces to increase airflow
- Avoid direct heat; prefer ambient air and fans
- Ensure complete interior dryness before wearing or storage
Long-Term Storage and Preventive Practices
Store shoes in a dry, ventilated area with breathable containers or open storage. Use silica gel packets or moisture absorbers in the closet or storage box to reduce humidity. Regularly air out shoes, especially after wearing in damp conditions, to prevent mildew buildup.
Rotate footwear to avoid prolonged moisture exposure and allow each pair ample drying time between uses. Lightly spray protective treatments designed for the material (fabric protectants, leather conditioners, or suede protectors) to create a barrier against moisture. Keep storage environments clean and free of mold-prone materials like damp cardboard.
Inspect shoes monthly for any signs of new mildew or odors, and address promptly with the cleaning methods described above. If mildew recurs despite preventive steps, consider replacing the affected pair or seeking professional cleaning for a deeper remediation. By combining cleaning, drying, and storage strategies, you reduce the likelihood of mildew returning over time.
- Use silica gel or moisture absorbers in storage
- Rotate footwear to reduce continuous moisture exposure
- Inspect monthly and apply preventive treatments as needed
Conclusion
Mildew on shoes is a manageable problem when addressed methodically: identify the mold, choose material-appropriate cleaners, and dry thoroughly while protecting the shoe’s integrity. By combining surface treatment with material-specific care and a proactive storage routine, you can restore comfort, extend the life of your footwear, and prevent future outbreaks. The key is balance—clean enough to remove spores without over-wetting delicate materials, then dry and store in a way that discourages recurrence. With patience and consistent practice, your shoes stay fresher, longer, and ready for whatever your day throws at them.
