Sports shoes, from running sneakers to gym trainers, endure sweat, dirt, and odors. Regular cleaning and sanitizing make them last longer and prevent germs, mold, and nasty odors from growing. This guide walks you through tried-and-true methods and environmentally friendly options for cleaning athletic footwear constructed from mesh, leather, or synthetic materials. Whether you have Nike Air Max, Adidas Ultraboost, or Under Armour cross-trainers, these tips work universally. Let’s dive in!

Why Clean and Sanitize Sports Shoes?
Sports shoes face unique challenges:
- Bacteria & Fungi: Moisture from sweat breeds microbes like Staphylococcus or Athlete’s Foot.
- Odors: Lingering smells from sweat or mildew.
- Material Damage: Dirt grinds into rubber soles, mesh uppers, or knit fabrics, causing wear.
- Aesthetic Value: Grass stains, mud, or discoloration ruin their look.
Regular maintenance protects your investment and health.
Tools & Materials Needed
Gather these non-toxic, affordable supplies:
- Cleaning Agents: Mild detergent, baking soda, white vinegar, hydrogen peroxide (3%), and oxygen bleach.
- Tools: Soft-bristle brush, microfiber cloth, old toothbrush, spray bottle.
- Sanitizers: Rubbing alcohol (70%), tea tree oil, UV shoe sanitizers.
- Odor Fighters: Activated charcoal bags, silica gel packets, cedar inserts.
- Drying Aids: Newspaper, silicone shoe trees.
Avoid harsh chemicals like chlorine bleach, which degrade materials like ethylene-vinyl acetate (EVA) midsoles.
Step-by-Step Cleaning Guide
1. Pre-Cleaning Prep
- Remove Laces & Insoles: Hand-wash laces with warm water + detergent. Soak insoles in a vinegar solution (1:1 water).
- Dry Brush: Knock off loose dirt with a soft-bristle brush.
2. Clean Based on Material
- Mesh or Knit Uppers (e.g., Nike Flyknit):
- Mix warm water + 1 tbsp mild detergent.
- Gently scrub with a toothbrush. For stains, use baking soda paste.
- Rinse with a damp cloth; air-dry away from sunlight.
- Leather or Synthetic (e.g., Adidas Stan Smith):
- Wipe with a vinegar-water mix (2:1).
- Condition leather with a pH-neutral cleaner.
- Rubber Soles: Scrub with an old toothbrush + hydrogen peroxide to whiten.
3. Machine Washing (If Safe)
- Check manufacturer guidelines (e.g., New Balance advises against machine washing for some models).
- Use a gentle cycle in a mesh laundry bag. Skip the dryer!
Sanitizing: Kill Germs Effectively
Cleaning removes dirt; sanitizing kills microbes. Try these methods:
- Rubbing Alcohol Spray: Spritz insides (test colorfastness first).
- Tea Tree Oil: Mix 10 drops with 1 cup of water for a natural antifungal.
- UV Shoe Sanitizers: Devices like SteriShoe eliminate 99.9% of bacteria.
- Freezing: Place shoes in a sealed bag overnight to kill odor-causing bacteria.
Note: Avoid steam cleaners on glue-heavy shoes—heat can loosen soles.
Odor Removal Hacks
- Baking Soda: Sprinkle inside overnight; vacuum out.
- Activated Charcoal: Place pouches in shoes for 24 hours.
- DIY Spray: 1 cup water + 2 tbsp vodka + 5 drops essential oil.
For stubborn smells, replace worn-out insoles with orthotic-friendly options.
Drying & Storage Tips
- Air-Dry Naturally: Stuff shoes with newspaper or silicone trees to retain shape.
- Avoid Heat: Dryers warp soles and shrink fabrics.
- Storage: Keep in a cool, dry place with cedar inserts to repel moths.
Seasonal Shoe Care
- Winter: Rinse salt stains immediately with a vinegar solution.
- Summer: Rotate shoes to reduce sweat buildup.
- Monsoon: Use waterproof sprays (e.g., Scotchgard) on synthetic uppers.
