My first pair of expensive leather boots. I swear, I baby-sat them. Wiped them down after every single wear, used the special conditioner—the whole nine yards. Then, that faint, musty smell started. A week later, it was undeniably mildew, crawling up the inside. I felt like a complete idiot, having spent a small fortune just to grow a science experiment.
It’s infuriating, isn’t it? You buy something meant to last, only for it to turn on you with a nasty fungal bloom. The sheer amount of marketing noise around shoe care is staggering. So, when you’re faced with this problem, you want answers, not more products to hoard.
Honestly, figuring out how to remove fungus from shoes naturally shouldn’t be rocket science, but it often feels like it. There are so many conflicting tips out there.
The Stink That Won’t Quit
That persistent, damp, earthy odor isn’t just unpleasant; it’s a sign that you’ve got more than just sweat brewing in there. Fungus, or mold and mildew, thrives in dark, moist environments – precisely what the inside of your shoes become after a long day. It can be particularly nasty if you’ve ever caught them in the rain, or if your feet tend to get a bit… enthusiastic with perspiration. I once bought a pair of really cool canvas sneakers for a trip, thinking they’d be perfect for walking around. After a day of heavy sightseeing in humid weather, they were so damp I could wring them out. That weekend trip turned into a week-long battle with a smell so bad, I had to keep them in a plastic bag in the hotel room. It was mortifying.
Cleanliness is key, obviously. But sometimes, even with regular washing, the spores dig in. This is where natural remedies come into play. They’re often less harsh than commercial chemicals and, crucially, don’t cost a fortune. We’re talking about things you probably already have in your kitchen or bathroom, ready to fight the funk.

Vinegar: Your Secret Weapon Against Fungal Foes
White vinegar is, in my humble opinion, the unsung hero of home cleaning. And yes, it’s brilliant for tackling shoe fungus. Its acidity is the key; it creates an environment that fungi absolutely loathe. Think of it like a tiny, natural exterminator. When I first heard about this, I was skeptical. Would my shoes smell like a salad dressing? The answer, thankfully, is no, not if you do it right. (See Also: How To Wear Brown Tall Boots)
So, how do you actually deploy this liquid marvel? Get yourself a spray bottle. Mix equal parts white vinegar and water. Shake it up. Then, lightly mist the inside of your shoes. Don’t soak them – you don’t want to reintroduce excess moisture. Just a good, even coating. Make sure you get into all the nooks and crannies, especially around the seams and the sole. Then, here’s the part that requires patience: let them air dry completely. This usually takes at least 24 hours, sometimes longer if it’s humid. The vinegar smell will dissipate as they dry, leaving behind… well, nothing but clean shoe.
Everyone says to use vinegar, and it’s good advice, but I disagree slightly on the concentration. I found that a 50/50 mix was sometimes too weak for really stubborn cases, especially on fabric shoes that seemed to absorb odors like sponges. For those, I’d bump it up to a 2:1 ratio of vinegar to water, or even straight vinegar if I was desperate and the material could handle it. You have to be brave; the initial smell is strong, but it really does work.
Baking Soda: The Odor-Absorbing Powerhouse
If vinegar is the exterminator, baking soda is the cleanup crew and the air freshener, all rolled into one. This stuff is a miracle for absorbing moisture and neutralizing odors. Seriously, I use it for everything from cleaning the fridge to deodorizing my carpet. For shoes, it’s a no-brainer.
After you’ve tackled the fungus with vinegar (or even as a standalone treatment for mild cases), baking soda is your best friend. Sprinkle a generous amount of baking soda directly into the shoes. You want a good layer covering the entire insole. Let it sit there for at least a few hours, but overnight is even better. Then, dump out the excess baking soda. You can use a vacuum cleaner with a hose attachment to get any lingering powder out of the fabric. This step is so simple, but it makes a massive difference in preventing that funky smell from returning. I’ve had shoes that I thought were goners, but a good overnight soak with baking soda inside them, followed by a light dusting, brought them back from the brink. It felt like I’d discovered a secret cheat code.
I’ve found that using a mesh bag or an old sock filled with baking soda and tying it off can be a cleaner way to apply it, especially for sneakers you wear frequently. You can just toss the bag in and pull it out when you need the shoes. It’s less messy than dumping powder everywhere.

Sunlight and Air: The Simplest (and Cheapest) Sanitisers
Sometimes, we overcomplicate things. The most basic elements are often the most effective. Fungus, like most living organisms, needs specific conditions to thrive. Take away those conditions, and it dies. Sunlight is a powerful natural disinfectant, and fresh air is its partner in crime.
Whenever possible, and I know this isn’t always feasible depending on where you live or the type of shoe, give your shoes a good airing out. Stash them near an open window, or better yet, on a sunny windowsill. The UV rays from the sun kill off bacteria and fungi. Plus, the fresh air circulates and helps dry out any residual moisture. I make it a habit to leave my gym shoes out on my balcony for a few hours after a particularly sweaty workout. It sounds almost too easy, right? But I swear, it stops the smell from even starting in the first place. This is as close to ‘how to remove fungus from shoes naturally’ as you can get without actually doing anything. It’s the foundation.
The key here is consistency. Don’t just do it once. Make it a part of your shoe care routine. Think of it like giving your shoes a mini-vacation in the sun. It’s a little thing, but it prevents big problems down the line. A study by the University of La Laguna in Spain actually found that shoes left in direct sunlight for about six hours had significantly fewer fungal colonies than those kept in the shade. They discovered that the UV radiation was potent enough to kill off a majority of the microbes. That’s scientific backing for my simple sun-drying habit!

Tea Tree Oil: Nature’s Antifungal Warrior
Alright, if you’re looking for something a bit more potent but still natural, tea tree oil is where it’s at. This essential oil has powerful antifungal and antibacterial properties. It’s a bit more of a heavy hitter than vinegar or baking soda, and you need to use it with a bit more caution. But for those really persistent, stubborn fungal infections that just won’t quit, it’s a lifesaver.
You don’t need much. Mix a few drops (I usually go with about 10-15 drops) into a cup of water. Put this mixture into a spray bottle. Lightly mist the inside of your shoes. Again, avoid soaking. The smell is quite strong, a bit medicinal, but it fades. The antifungal properties are potent, and it’s surprisingly effective at eradicating the microscopic nasties causing the problem. After spraying, let them dry thoroughly, just like you would with the vinegar solution. I found this particularly useful for my running shoes, which seemed to be perpetually damp and prone to that ‘locker room’ smell, no matter what I did. The tea tree oil was the only thing that really knocked it out for good. (See Also: How To Wear Chelsea Boots With Chinos)
When using tea tree oil, always do a small patch test on an inconspicuous area of the shoe material if you’re concerned about discoloration, especially with delicate leathers or suedes. Most fabrics are fine, but it’s better to be safe than sorry. I learned this the hard way with a pair of light-colored suede loafers where I got a bit too enthusiastic with the application, and it left a slight discoloration. It wasn’t noticeable to most people, but I knew.

Preventing Future Fungal Fiascos
Honestly, the best way to deal with fungus is to stop it before it starts. It’s like rust on a car; a small spot can turn into a disaster if ignored. So, here’s what I do to keep my shoes from staging their own fungal invasion.
- Rotate Your Shoes: Don’t wear the same pair every single day. Give them at least 24 hours to dry out completely between wears. This is probably the single most impactful habit.
- Dry Them Out Promptly: If your shoes get wet, stuff them with newspaper or paper towels immediately to absorb moisture. Then, air dry them thoroughly away from direct heat, which can damage materials.
- Use Shoe Trees: Cedar shoe trees are fantastic. They absorb moisture and help maintain the shoe’s shape. They also impart a pleasant, natural scent that discourages mold. I spent around $70 on a set of good cedar shoe trees a few years back, and they’ve paid for themselves tenfold in shoe longevity.
- Washable Insoles: For sneakers and athletic shoes, look for ones with removable, washable insoles. Pulling them out and washing them separately is a game-changer.
- Keep Your Feet Clean and Dry: This sounds obvious, but it’s foundational. Wash your feet daily, dry them thoroughly, and wear clean, moisture-wicking socks.

Faq: Your Burning Questions Answered
Can I Use Rubbing Alcohol to Remove Fungus From Shoes?
Yes, rubbing alcohol (isopropyl alcohol) can be used. Like vinegar, its antiseptic properties can help kill fungus. Mix it with water in a 1:1 ratio and spray inside the shoes. Allow them to dry completely. Be cautious with delicate materials, as alcohol can sometimes cause them to stiffen or discolor.
How Long Does It Take for Fungus to Grow in Shoes?
Fungal spores are often already present on surfaces. Given the right conditions—warmth, moisture, and darkness—fungus can start to become noticeable, both visually and by smell, within a matter of days to a week. Consistent drying and good ventilation are your best defenses against rapid growth.
Should I Throw Away Shoes with Fungus?
Not necessarily. For many common shoe materials like canvas, synthetic leathers, and even some treated leathers, natural treatments can be very effective. However, if the fungus has deeply penetrated porous materials like untreated suede or is extensive and causing the shoe material to degrade, it might be time to consider replacement to avoid spreading spores to other items or your feet.
What’s the Difference Between Mold and Mildew in Shoes?
Both are types of fungi that thrive in damp conditions. Mildew typically appears as a surface growth, often white or gray, and can have a powdery or fuzzy texture. Mold can be more varied in color (black, green, blue, white) and can penetrate deeper into materials, often with a more slimy or fuzzy appearance. Both can cause that unpleasant musty odor and should be treated.
Verdict
So, there you have it. How to remove fungus from shoes naturally isn’t some mystical art; it’s about using common household items and a bit of common sense. You’ve got vinegar for the heavy lifting, baking soda for the odor-tackling, and the simple power of sun and air to keep things fresh. Don’t let those pesky spores win; your footwear deserves better.
My biggest takeaway from years of battling these fungal invaders? Prevention is so much easier than the cure. Make a habit of rotating your shoes and drying them out properly, and you’ll save yourself a lot of frustration (and money). It sounds basic, but it’s the foundation for keeping your shoes smelling great and fungus-free.
Seriously, give these natural methods a shot. For truly stubborn cases, tea tree oil is your secret weapon. Just remember to be patient and let your shoes dry thoroughly after any treatment. You’ll be amazed at how much life you can breathe back into them, and how much better your feet will feel.
