How to Clean Shoes Inside from Fungus

Fungal growth inside shoes is a common but often ignored problem. Warm, dark, and moist environments inside footwear create the perfect breeding ground for fungus. This can lead to bad odor, itching, skin infections, and long-term foot health issues.

If your shoes smell musty or you notice recurring foot infections, it’s time to learn How to Clean Shoes Inside from Fungus properly and safely.

Why Fungus Grows Inside Shoes:

Fungi thrive in conditions that are:

Warm
Moist
Dark
Poorly ventilated

Shoes naturally create this environment, especially when:

Worn for long hours
Used during sweating
Not dried properly
Stored in closed spaces

Fungal spores can survive inside shoes for days or even weeks if not treated properly.

Common Signs of Fungal Contamination in Shoes:

You may have fungus inside your shoes if you notice:

Persistent bad odor
White or yellow powder-like residue
Itchy feet after wearing shoes
Recurring athlete’s foot
Damp or sticky shoe interior
Skin peeling or redness

Early treatment is important to prevent reinfection.

How to Clean Shoes Inside from Fungus | Easy Safe Methods:

Step 1: Remove Insoles and Laces

Start by fully opening the shoe:

Take out insoles
Remove shoelaces
Open shoe tongue

Why this is important:

Exposes hidden fungal areas
Allows deeper cleaning
Prevents recontamination

Step 2: Dry the Shoes Completely First

Before applying any cleaning solution:

Place shoes in sunlight or ventilated area
Let them dry for several hours

Important:

Never clean fungus in wet shoes—it spreads spores further.

Step 3: Brush Out Surface Dirt and Debris

Use a dry brush or toothbrush:

Remove dust
Scrape off visible residue
Focus on inner corners

This prepares the shoe for deep cleaning.

Step 4: Prepare Antifungal Cleaning Solution

You can use simple household ingredients:

Option 1: Vinegar Solution

1 part white vinegar
1 part water

Option 2: Baking Soda Paste

Baking soda + small amount of water

Option 3: Mild soap + warm water

Vinegar is especially effective against fungus due to its acidic properties.

Step 5: Clean Inside the Shoes Thoroughly

Now begin deep cleaning:

Method

Dip a cloth or soft brush in solution
Scrub inner lining gently
Focus on heel, toe, and insole area

Tip

Do not soak shoes fully unless they are washable fabric sneakers.

Step 6: Disinfect Insoles and Laces Separately

Insoles

Soak in vinegar solution for 15–20 minutes
Scrub gently
Rinse and dry completely

Laces

Wash in warm soapy water
Air dry in sunlight

Step 7: Apply Antifungal Treatment Inside Shoes

After cleaning:

Spray diluted vinegar or antifungal spray inside
Let it sit for 10–15 minutes
Wipe excess moisture

This step kills remaining spores.

Step 8: Sun Drying for Complete Disinfection

Sunlight is a natural antifungal agent.

Place shoes in direct sunlight for a few hours
Ensure both inside and outside are dry

Important

UV rays help kill remaining fungal spores naturally.

Step 9: Use Odor and Moisture Absorbers

After drying:

Add baking soda inside shoes overnight
Or use silica gel packets
Charcoal pouches also help

These absorb moisture and prevent fungus from returning.

Step 10: Reassemble Shoes Properly

Once fully dry:

Insert clean insoles
Relace shoes
Store in ventilated area

Never store damp shoes in closed cabinets.

Effective Home Remedies for Shoe Fungus:

1. Vinegar Spray

Kills most fungal spores and bacteria.

2. Baking Soda

Absorbs moisture and neutralizes odor.

3. Tea Tree Oil

Natural antifungal agent (add few drops in water spray).

4. Sunlight Exposure

Natural disinfectant for shoes.

Expert Insight:

Footwear hygiene is closely linked to skin health. Medical studies and dermatology practices emphasize that untreated fungal infections can easily spread between shoes and feet.

According to foot health and hygiene guidelines supported by the Centers for Disease Control and Prevention, fungal infections like athlete’s foot can persist in contaminated footwear and reinfect the skin if shoes are not properly disinfected.

Proper shoe hygiene is therefore essential not just for comfort, but for preventing recurring infections.

Common Mistakes to Avoid:

Wearing shoes before they are fully dry
Using strong bleach inside delicate shoes
Storing shoes in closed, damp spaces
Ignoring insoles during cleaning
Reusing infected socks without washing

How to Prevent Fungus Inside Shoes:

1. Keep Feet Dry

Moisture control is key.

2. Rotate Shoes

Do not wear the same pair daily.

3. Use Moisture-Wicking Socks

Cotton or breathable materials help.

4. Air Shoes After Use

Let them breathe for at least 12–24 hours.

5. Use Antifungal Powder

Prevents fungal growth inside shoes.

Benefits of Cleaning Shoes from Fungus:

Eliminates bad odor
Prevents reinfection of feet
Improves shoe lifespan
Enhances hygiene and comfort
Reduces skin irritation

When to Replace Shoes Instead of Cleaning:

Sometimes cleaning is not enough. Replace shoes if:

Fungus keeps returning after cleaning
Inner lining is heavily damaged
Strong odor persists permanently
Material is degraded or moldy
