After every session is the honest answer. They're soaked with sweat, and sweat sitting in cotton breeds bacteria fast. Stretching it to two or three sessions is the realistic minimum if every-time isn't happening.
Once you go past that, the wraps stiffen, smell, and start growing things you don't want against your skin. They also start eating into your gloves from the inside, which is way more expensive to deal with than washing wraps.
Why Frequency Matters More Than People Realize
Hand wraps are the closest piece of gear to your skin during training. They sit on your knuckles, palms, and wrists for the entire session, soaking up everything your hands produce. Sweat by itself is mostly odorless, but the bacteria that feed on it multiply fast in warm damp fabric.
That's where the smell comes from, and it's also where the second problem starts. Your wraps sit inside your gloves. Whatever bacteria are living in your wraps are getting absorbed into the foam padding of your gloves with every session. Most of the deep glove smell people complain about isn't from the gloves themselves. It's from wraps that nobody washed.
The Simple Rule
If they came out of your gloves wet with sweat, wash them. The harder the session, the wetter they get, the sooner they need to be washed. That's basically the whole rule.
How to Wash Them So They Last
Close the velcro before washing so it doesn't shred the fabric. Drop the wraps into a mesh laundry bag so they don't tangle into a knot in the machine. Cold water, gentle cycle, mild detergent. Skip the dryer entirely. Heat destroys the elastic and warps the velcro backing fast.
Air dry only. Hang them fully unrolled so both sides get airflow. A door frame, a towel bar, the back of a chair. Folded over a flat surface means one side stays damp, and damp wraps start growing mold within hours.
The air drying step is where most people give up. Wraps tangle on hangers, fall off towel racks, or end up draped over something with one side staying damp. The Drago Roller clips over any door and holds both wraps fully unrolled and flat while they air dry. Both wraps get even airflow, dry properly, and stay ready to roll back up when the next session comes around. It also comes with a mesh laundry bag, so the wash side of the routine is covered too.
Own More Pairs
If you train more than twice a week, one pair isn't enough. Wraps need to fully dry before they go back on, and you don't want to be rushing a wash the night before a session. The simple rule: own one more pair than the number of days you train per week. Train three times a week, own four pairs. That way you've always got a clean dry pair ready and the rotation extends the life of every pair.
