[Home Tips] How to remove the odor from the shoe cabinet in a long-term manner?

👃 Why are shoe cabinets in Hong Kong particularly prone to odor?

Hong Kong has a high-humidity subtropical climate , with an average annual humidity of about 77%, and can reach over 90% during the rainy season. This environment is ideal for:

  • 🦠Bacteria growth (sweat residue on the soles and insoles)
  • 🌱Mold growth (leather shoes and cloth shoes are most prone to mold)
  • 💧Moisture accumulation (poor ventilation in shoe cabinets prevents moisture from dissipating easily)

In addition, Hong Kong people often walk and take the subway, and their feet sweat a lot in hot weather. The inside of their shoes is like a "warm and humid bacterial paradise", and odor is naturally endless.


⚠️ Health risks of shoe cabinet odor

Odors are not just a matter of "stink"; they are actually caused by a combination of microorganisms and chemicals:

  • Mold spores : can cause nasal allergies, asthma, and skin allergies
  • Bacterial metabolites : produce volatile organic compounds (VOCs), which may cause dizziness and throat discomfort if inhaled for a long time
  • Ammonia and fatty acids (produced from sweat): Irritation of the respiratory tract

💡Editor 's opinion : To deal with odor in shoe cabinets, you must "eliminate the root cause + prevent moisture + inhibit bacteria." Simply covering it up with fragrance will only have a temporary effect.


🛠️ Hong Kong's long-term moisture and deodorization solution

The following methods have been tested by the editor and sorted out from online materials. They are divided into three steps : source treatment, dehumidification and moisture prevention, and antibacterial purification .


1️⃣ Source treatment - starting with shoes

  1. Sole cleaning
    • Every time I come home, I first pat off the mud and sand at the door and wipe the bottom with a damp cloth to prevent mud and mold.
  2. Insole cleaning/replacement
    • It is recommended to clean cloth insoles weekly, and leather insoles can be disinfected with alcohol spray.
  3. Dry shoe habits
    • If your shoes get wet in the rain, first absorb the water with a paper towel, then use a fan or shoe dryer to dry them. Never put them directly into the shoe cabinet.
  4. Separate shoe storage
    • Place sneakers, leather shoes, and slippers separately to avoid odor contamination.

2️⃣ Dehumidification and moisture prevention - blocking the source of musty odor

  1. Shoe cabinet location selection
    • Avoid placing it near a damp wall, it is best to place it near a ventilated area.
  2. Use absorbent products
    • Activated carbon bag : absorbs moisture and odor, replace every 1-2 months.
    • Silicone desiccant : can be dried and reused repeatedly, which is environmentally friendly and saves money.
  3. Keep the air flowing
    • Do not keep the shoe cabinet door closed for a long time. Leave a gap or install ventilation holes.
  4. Electric dehumidification assist
    • During the rainy season, you can place a small dehumidifier or USB dehumidifier in the shoe cabinet, which consumes low power and is always on.

3️⃣ Antibacterial purification - completely eliminate the source of odor

  1. natural deodorant
    • Baking soda : absorbs acidic odors (such as sweat).
    • Coffee grounds : good odor absorption effect, and a light coffee aroma☕.
  2. Essential oils are antibacterial
    • Tea tree, eucalyptus, and lavender essential oils have natural antibacterial properties and can be dropped on cotton balls and placed in the shoe cabinet.
  3. Ultraviolet germicidal lamp
    • Turn it on for 10-15 minutes every week (make sure no one and no pets are watching directly) to effectively kill bacteria and prevent mildew.
  4. Ozone generator (low concentration)
    • Running for a short time can decompose odor molecules, but ventilation is required after use to prevent the human body from inhaling too much ozone.

📋 Editor's long-term odor removal solution (proven effective)

I live in an old building in Kowloon, and my shoe cabinet used to have a musty smell. I later implemented the following solution:

  1. After you get home, spray the inside of each pair of shoes with alcohol and put in a desiccant bag.
  2. Place activated carbon bags on the bottom layer of the shoe cabinet and baking soda cans on the top layer.
  3. Add a USB dehumidifier during the rainy season, which runs 24 hours a day with low power consumption.
  4. Sterilize with ultraviolet light once a month.

💡Result: The odor is almost gone, even my leather shoes are free of mold spots. The cost of replacing the desiccant and carbon bag is less than $150 a year, long-lasting and cost-saving💰.


✅ Editor's recommendations for purchasing deodorizing and moisture-proof products

  • Daily moisture protection : silica gel desiccant (reusable) + activated carbon bag
  • Quick odor removal : baking soda/coffee grounds
  • Deep sterilization : UV sterilization lamp (pay attention to safety)
  • A must-have for rainy season : a USB mini dehumidifier
