How to Wash Knee Sleeves (Without Ruining Them)
Hand wash your knee sleeves in cold water with a small amount of mild soap, then air dry — never machine wash or put neoprene knee sleeves in the dryer. Heat and agitation are what break down neoprene over time, not regular use.
How to Wash Knee Sleeves, Step by Step
- Fill a sink or basin with cold water and a small amount of mild, unscented soap (dish soap or a gentle detergent both work)
- Submerge the sleeves and gently work the soap through the fabric with your hands — focus on the interior, where sweat builds up most
- Rinse thoroughly in cold water until no soap remains
- Squeeze out excess water gently — don't wring or twist the neoprene
- Lay flat or hang to air dry, away from direct heat or sunlight
Depending on training frequency, washing after every 3-5 uses is usually enough to prevent odor buildup without over-handling the material.
What Not to Do
- Never machine wash — the agitation breaks down the neoprene's internal structure over time
- Never put them in the dryer — heat is the fastest way to cause neoprene to crack, stiffen, or shrink
- Avoid bleach or harsh detergents — these degrade neoprene and can irritate skin on the next wear
- Don't leave them wet and balled up — this is the most common cause of lingering odor and mildew
Dealing With Odor Between Washes
If you train often and can't wash after every session, let the sleeves fully air dry between uses rather than stuffing them straight back in a gym bag. A light mist of fabric-safe odor spray can help, but proper air drying does most of the work.
The Bottom Line
Cold water, mild soap, hands only, air dry — that's the entire process. Skip the washing machine and dryer entirely, and a quality pair of 7mm neoprene knee sleeves will hold up for years of regular training.
