Quick Tips to Kill Mildew in Shoes:
Dry them out: Keep your shoes in a dry, well-ventilated area.
Clean regularly: Use rubbing alcohol, white vinegar, or baking soda for cleaning.
Use desiccants: Silica gel packs can help absorb extra moisture.

Finding mildew in your shoes can be both disappointing and concerning, especially if you’re in the shoe manufacturing or retail business where product quality directly impacts your reputation. Mildew, a type of mold, thrives in moist, humid conditions. When it finds a cozy spot in shoes, it can cause a musty odor, discoloration, and even damage to the footwear.

Why does mildew choose your shoes? Simply put, shoes often provide the perfect environment for mildew: humidity from sweat or external moisture and inadequate ventilation. Whether it’s a pair forgotten in a damp basement or sneakers worn through rainy days, the resulting moisture can invite mildew to settle in.

The solution starts with prevention: ensuring shoes are thoroughly dry before they’re stored and maintaining a low-humidity environment can significantly reduce the risk. For shoe manufacturers and retailers, understanding these basics is crucial to advising customers and managing inventory.

Identifying Mildew in Your Shoes

When it comes to keeping your shoes in top-notch condition, spotting mildew early is crucial. Let’s dive into how you can identify this unwelcome guest in your footwear.

Musty Odor

First up, let’s talk about the smell. If you’ve ever caught a whiff of something musty or damp when grabbing your shoes, that’s a big red flag. Mildew has a distinct, unpleasant odor that’s hard to ignore. This smell is your first clue that something’s not right inside your shoe.

Green or Black Patches

Next, take a good look at your shoes. Do you see any green or black patches? These colors are tell-tale signs of mildew growth. It might start small, but given time, these patches can spread, covering more of your shoe. These visual cues are a clear indication that mildew has made itself at home.

Fuzzy Texture

Lastly, let’s not forget about the texture. Mildew often has a fuzzy or velvety texture. If the inside of your shoe feels different than usual, or if you notice any fuzzy growths, it’s time to take action. This physical change is a sign that mildew spores are thriving.

Identifying mildew early is key to saving your shoes and keeping them fresh and clean. Armed with this knowledge, you’re ready to move on to tackling mildew head-on with effective cleaning agents and methods. Let’s dive into how you can kill mildew in shoes and bring your footwear back to life.

Causes of Mildew Growth in Shoes

When we talk about mildew in shoes, it’s like discussing a mystery where the usual suspects are always moisture and its sneaky accomplices. Understanding these can help you keep your kicks in tip-top shape. Let’s break down the main culprits:

Moisture Buildup

The number one villain in the story of shoe mildew is moisture buildup. Whether it’s from stepping in a puddle or just the natural sweat from your feet, moisture is a constant threat. It’s like a party invitation for mildew, saying, “Hey, come grow here!”

Poor Storage

Storing your shoes in a damp, dark place is like rolling out the red carpet for mildew. Places like basements or closed-off closets without proper ventilation are prime spots for mildew to settle in. It’s crucial to store your shoes in a dry, airy space to cut off mildew’s lifeline.


Our feet sweat, a lot. This isn’t news, but it’s a significant factor in mildew growth. The warm, damp environment inside a shoe after a long day provides a perfect breeding ground for mildew. It’s the moisture from perspiration that mildew thrives on, making your shoes its home.

Rain Exposure

Lastly, getting caught in the rain can do more than just dampen your spirits; it can soak your shoes. Even if they seem to dry on the outside, the insides can remain damp, especially if they’re not dried properly. This residual moisture is like a welcome mat for mildew.

Understanding these causes is your first step in the battle against shoe mildew. By keeping moisture at bay, storing your shoes properly, and ensuring they’re dry before you tuck them away, you can significantly reduce the chances of mildew making a home in your footwear. Prevention is always better than cure, so take these steps to heart and keep your shoes mildew-free. Now, let’s move on to the best ways to clean and kill mildew in shoes, ensuring your kicks stay fresh and clean.

Effective Cleaning Agents and Methods

After identifying mildew in your shoes, the next step is to kill and remove it. Here’s how to do it effectively, using simple, accessible cleaning agents.

Cleaning Canvas Shoes

For canvas shoes, a mixture of rubbing alcohol and water is your go-to solution. Here’s a simple breakdown:

  • Mix equal parts of rubbing alcohol and water in a bowl.
  • Dip a brush into the solution and gently scrub the affected areas.
  • Allow the shoes to air dry completely, away from direct heat to prevent any damage.

This method is effective because rubbing alcohol acts as a disinfectant, killing the mildew spores.

Cleaning Leather Shoes

Leather shoes require a bit more care:

  1. Create a cleaning solution with equal parts of rubbing alcohol and water.
  2. Wipe the shoes with this mixture using a soft cloth.
  3. Apply a leather saddle soap to clean deeper and condition the leather.
  4. Dry the shoes naturally, then condition them to restore moisture lost during the cleaning process.

The saddle soap not only cleans but also helps in maintaining the leather’s flexibility and shine.

Cleaning Suede Shoes

Suede shoes are the most delicate:

  • Gently brush off any surface mildew with a soft-bristled brush.
  • Apply a mixture of white vinegar and water or rubbing alcohol and water to the affected areas with a soft cloth.
  • Let the shoes dry naturally without exposing them to direct heat.

The vinegar or alcohol will kill the mildew without damaging the sensitive suede material.

Removing Mildew Odor

After cleaning, your shoes might still have a musty odor. Here’s how to tackle it:

  • Baking soda: Sprinkle inside the shoes and leave overnight. Vacuum or shake out the residue.
  • Tea tree oil: Mix a few drops with water in a spray bottle. Spray inside the shoes and let them air dry.
  • Ammonia: For very stubborn odors, wipe the inside with a cloth dampened in a diluted ammonia solution. Use in a well-ventilated area and rinse thoroughly afterward.

The key to effectively killing mildew in shoes is not just about removing the visible signs but also ensuring the spores are eradicated and the odors neutralized. By following these methods, you can rescue your shoes and extend their life, keeping them fresh and clean. Moving forward, adopting preventive measures will help you avoid the recurrence of mildew, ensuring your shoes remain in the best condition possible.

Preventive Measures to Keep Shoes Mildew-Free

After tackling the challenge of how to kill mildew in shoes, the next crucial step is to prevent it from coming back. Let’s dive into some simple yet effective strategies to keep your shoes fresh and mildew-free.

Proper Storage

The way you store your shoes can make a big difference. Avoid dark, damp places like basements or closed closets that lack ventilation. Instead, opt for a well-ventilated area where air can circulate freely around your shoes. If you must keep them in a closet, consider leaving the door open when possible or use a closet dehumidifier.

Silica Gel Packs

These little packets are not just packing material to be thrown away. Silica gel packs are excellent at absorbing moisture. Tuck a few into each shoe before storing them, especially if you live in a humid climate. They’ll help keep the inside of your shoes dry and unfriendly to mildew spores.

Shoe Racks

Using shoe racks not only keeps your shoes organized but also ensures they are not piled on top of each other, restricting airflow. A shoe rack allows each pair to breathe, reducing the risk of moisture buildup. If possible, choose racks that allow air circulation from all sides.

Drying Before Storage

Never put your shoes away wet. Whether they’ve gotten wet from rain or sweat, drying them thoroughly is vital. Remove the insoles and laces and let them air dry, or use a gentle fan to speed up the process. Avoid direct heat sources like radiators, as they can damage the shoes.

Moisture-Wicking Socks

Invest in good-quality moisture-wicking socks. These socks are designed to pull moisture away from your skin, keeping your feet dry. Less moisture in your shoes means a lower chance of mildew growth. It’s a simple change that can have a significant impact on keeping your shoes in top condition.

By incorporating these preventive measures into your routine, you can significantly reduce the risk of mildew returning to your shoes. Prevention is key. A little effort in storing and caring for your shoes can save you a lot of trouble in the long run. With these strategies, you’re well on your way to ensuring your footwear remains clean, fresh, and mildew-free.
