Knee sleeves work hard. They absorb sweat, body heat, and bacteria every time you train. If you don’t wash them properly, they can start to smell bad, lose elasticity, or even crack over time.
Many people ruin their knee sleeves by throwing them in the washing machine or drying them in heat. In this guide, I’ll show you how to wash neoprene knee sleeves the right way, so they last longer and stay supportive.
Why Proper Washing Matters
Neoprene is strong, but it’s also sensitive to:
- High heat
- Strong detergents
- Rough washing cycles
Wrong washing can cause:
- Loose fit
- Reduced compression
- Bad odor that won’t go away
- Shorter lifespan
If you’ve invested in good knee sleeves, proper care is non-negotiable.
How Often Should You Wash Knee Sleeves?
- Light use (1–2 times/week): Wash every 3–4 workouts
- Heavy training or sweaty sessions: Wash after every workout
- Competition use: Always wash after use
Sweat left inside neoprene allows bacteria to grow, which causes odor and skin irritation.
Best Way to Wash Neoprene Knee Sleeves (Step-by-Step)
Step 1: Hand Wash Only (Best Method)
Hand washing is the safest way to clean knee sleeves.
You’ll need:
- Lukewarm water
- Mild detergent or gentle soap
- A bucket or sink
How to do it:
- Fill the sink with lukewarm water
- Add a small amount of mild detergent
- Submerge the knee sleeves
- Gently squeeze and rub them for 2–3 minutes
- Focus on the inside (this holds the most sweat)
Do NOT scrub hard or twist aggressively.
Step 2: Rinse Thoroughly
Rinse with clean water until all soap is gone.
Leftover detergent can damage neoprene and cause skin irritation.
Step 3: Remove Water Correctly
- Gently squeeze (do not wring)
- Press with a towel to absorb excess water
Never twist knee sleeves like clothes.
Step 4: Air Dry Only
- Hang or lay flat
- Dry in a shaded, well-ventilated area
Do NOT:
- Use a dryer
- Place in direct sunlight
- Put near heaters
Heat breaks down neoprene fibers.
Can You Machine Wash Knee Sleeves?
Not recommended, but if you must:
- Use cold water only
- Gentle cycle
- Place in a mesh laundry bag
- No fabric softener
- No spin cycle
Machine washing reduces the lifespan over time.
How to Remove Bad Smell from Knee Sleeves
If your knee sleeves already smell:
Option 1: Vinegar Soak (Once a Month)
- Mix 1 part white vinegar + 3 parts water
- Soak for 15–20 minutes
- Rinse thoroughly
Option 2: Baking Soda
- Sprinkle baking soda inside
- Leave overnight
- Rinse the next day
Both methods help kill odor-causing bacteria.
What NOT to Do (Common Mistakes)
Using bleach
Using fabric softener
Drying in sunlight
Ironing
Storing while damp
These mistakes permanently damage neoprene.
How to Store Knee Sleeves After Washing
- Make sure they are completely dry
- Store in a cool, dry place
- Avoid folding tightly
- Do not leave gym bags for days
Proper storage = longer life.
How Long Do Neoprene Knee Sleeves Last?
With proper care:
- 6–12 months for heavy lifters
- 1–2 years for moderate training
Poor washing habits can reduce life by half.
Final Thoughts
Washing neoprene knee sleeves correctly is simple, but most people do it wrong.
Hand wash, air dry, avoid heat — that’s it.
Take care of your knee sleeves, and they’ll take care of your knees.
